APPLICATION NOTE — ZENER VOLTAGE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL = θLAPD + TA.
θLA is the lead-to-ambient thermal resistance (°C/W) and PD is
the power dissipation. The value for θLA will vary and depends
on the device mounting method. θLA is generally 30 to 40°C/W
for the various clips and tie points in common use and for
printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by: TJ = TL + ∆TJL.
∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for dc power:
∆TJL = θJLPD.
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ(∆TJ) may be estimated. Changes in
voltage, VZ, can then be found from:
∆V = θVZTJ.
θVZ, the zener voltage temperature coefficient, is found from
Figures 4 and 5.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Surge limitations are given in Figure 7. They are lower than
would be expected by considering only junction temperature,
as current crowding effects cause temperatures to be ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 7 be exceeded.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance Designation
The type numbers shown have tolerance designations as follows:
1N4370A series: ±5% units, C for ±2%, D for ±1%.
1N746A series: ±5% units, C for ±2%, D for ±1%.
1N957B series: ±5% units, C for ±2%, D for ±1%.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead
temperature of 30°C ±1°C and 3/8″ lead length.
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)
Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage
(VZ) is known at the operating point, the maximum zener current may be increased and is
limited by the derating curve.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
The type numbers shown have a standard tolerance of ±5% on the nominal zener voltage.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal Zener Voltage is measured with the device junction in the thermal equilibrium with
ambient temperature of 25°C.
NOTE 3. ZENER IMPEDANCE (ZZT) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.
NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)
Maximum zener current ratings are based on maximum zener voltage of the individual units.
NOTE 5. REVERSE LEAKAGE CURRENT IR
Reverse leakage currents are guaranteed and are measured at VR as shown on the table.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
The “B” suffix type numbers listed are ±5% tolerance of nominal VZ.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambi-
ent temperature of 25°C.
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current
having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.
NOTE 4. REVERSE LEAKAGE CURRENT IR
Reverse leakage currents are guaranteed and are measured at VR as shown on the table.
NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)
The maximum current shown is based on the maximum voltage of a ±5% type unit, therefore,
it applies only to the “B” suffix device. The actual IZM for any device may not exceed the value
of 400 milliwatts divided by the actual VZ of the device.
NOTE 6. MAXIMUM REGULATION FACTOR (∆VZ)
∆VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device
junction in thermal equilibrium.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL = θLAPD + TA.
θLA is the lead-to-ambient thermal resistance (°C/W) and PD is
the power dissipation. The value for θLA will vary and depends
on the device mounting method. θLA is generally 30 to 40°C/W
for the various clips and tie points in common use and for
printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by: TJ = TL + ∆TJL.
∆TJL is the increase in junction temperature above the lead
temperature and may be found as follows:
∆TJL = θJLPD.
θJL may be determined from Figure 3 for dc power condi-
tions. For worst-case design, using expected limits of IZ, limits
of PD and the extremes of TJ(∆TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
∆V = θVZ ∆TJ.
θVZ, the zener voltage temperature coefficient, is found from
Figure 2.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Surge limitations are given in Figure 5. They are lower than
would be expected by considering only junction temperature,
as current crowding effects cause temperatures to be ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 5 be exceeded.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL = θLA PD + TA
θLA is the lead-to-ambient thermal resistance (°C/W) and
PD is the power dissipation. The value for θLA will vary and
depends on the device mounting method. θLA is generally
30–40°C/W for the various clips and tie points in common
use and for printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by: TJ = TL + ∆TJL
∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for a train of
power pulses (L = 3/8 inch) or from Figure 10 for dc power .
∆TJL = θJL PD
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ (∆TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
∆V = θVZ ∆TJ
θVZ, the zener voltage temperature coefficient, is found from
Figures 5 and 6.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Data of Figure 2 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 3. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 3 be exceeded.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance designation — Device tolerances of ±5% are indicated by a “B” suffix.
NOTE 2. SPECIAL SELECTIONS AVAILABLE INCLUDE:
Nominal zener voltages between those shown and ±1% and ±2% tight voltage tolerances.
Consult factory.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when meausred at 90 seconds while maintaining the
lead temperature (TL) at 30°C ±1°C, 3/8″ from the diode body.
NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.

NOTE 1. TOLERANCES
Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when measured at 40 ms ±10 ms 3/8″ from the diode
body, and an ambient temperature of 25°C (+8°C, –2°C)
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.
NOTE 4. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers shown indicate a tolerance of ±5%.
NOTE 2. ZENER VOLTAGE (VZ) AND IMPEDANCE (ZZT & ZZK)
T est conditions for zener voltage and impedance are as follows: IZ is applied 40 ± 10 ms prior
to reading. Mounting contacts are located 3/8″ to 1/2″ from the inside edge of mounting clips
to the body of the diode. (TA = 25°C +8, –2°C).
NOTE 3. SURGE CURRENT (ir)
Surge current is specified as the maximum allowable peak, non-recurrent square-wave cur-
rent with a pulse width, PW, of 8.3 ms. The data given in Figure 6 may be used to find the
maximum surge current for a square wave of any pulse width between 1ms and 1000 ms by
plotting the applicable points on logarithmic paper. Examples of this, using the 3.3 V and
200 V zeners, are shown in Figure 7. Mounting contact located as specified in Note 3. (TA =
25°C +8, –2°C.)
NOTE 4. VOLTAGE REGULATION (∆VZ)
T est conditions for voltage regulation are as follows: VZ measurements are made at 10% and
then at 50% of the IZ max value listed in the electrical characteristics table. The test current
time duration for each VZ measurement is 40 ± 10 ms. (TA = 25°C +8, –2°C). Mounting contact
located as specified in Note 2.
NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)
The maximum current shown is based on the maximum voltage of a 5% type unit, therefore,
it applies only to the B-suffix device. The actual IZM for any device may not exceed the value
of 5 watts divided by the actual VZ of the device. TL = 75°C at 3/8″ maximum from the device
body.
NOTE 6. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerance such as
±1% and ±2%. Consult factory.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL = θLA PD + TA
θLA is the lead-to-ambient thermal resistance and PD is the
power dissipation.
Junction Temperature, TJ, may be found from:
TJ = TL + ∆TJL
∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 4 for a train of
power pulses or from Figure 5 for dc power.
∆TJL = θJL PD
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ (∆TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
∆V = θVZ ∆TJ
θVZ, the zener voltage temperature coefficient, is found from
Figures 2 and 3.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Data of Figure 4 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 6. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 6 be exceeded.
