TOLERANCE AND VOLTAGE DESIGNATION (VZ) Reverse leakage currents are guaranteed and measured at VR as shown on the table. The type numbers shown have a standard tolerance of 5% on the nominal Zener voltage, C for 2%, D for 1%. NOTE 4. MAXIMUM VOLTAGE CHANGE (VZ) NOTE 2. MAXIMUM ZENER CURRENT RATINGS (IZM) NOTE 5. ZENER VOLTAGE (VZ) MEASUREMENT Maximum Zener current ratings are based on maximum Zener voltage of the individual units and JEDEC 250 mW rating. Voltage change is equal to the difference between VZ at 100 A and VZ at 10 A. Nominal Zener voltage is measured with the device junction in thermal equilibrium at the lead temperature at 30C 1C and 3/8 lead length. NOTE 3. REVERSE LEAKAGE CURRENT (IR) 500 mW DO-35 Glass Data Sheet 6-2 Motorola TVS/Zener Device Data APPLICATION NOTE -- ZENER VOLTAGE Since the actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junction temperature under any set of operating conditions in order to calculate its value. The following procedure is recommended: Lead Temperature, TL, should be determined from: TL = LAPD + TA. LA is the lead-to-ambient thermal resistance (C/W) and PD is the power dissipation. The value for LA will vary and depends on the device mounting method. LA is generally 30 to 40C/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 measured value of TL, the junction temperature may be determined by: JL , JUNCTION-TO-LEAD THERMAL RESISTANCE (C/W) GENERAL DATA -- 500 mW DO-35 GLASS VZ, 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 extremely high in small spots, resulting in device degradation should the limits of Figure 7 be exceeded.

Typical Thermal Resistance 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 = JLPD. For worst-case design, using expected limits of IZ, limits of PD and the extremes of TJ(TJ) may be estimated.
