3EZ3.9D5 thru 3EZ200D5
DESCRIPTION APPEARANCE
The 3EZ3.9D5 thru 3EZ200D5 series of axial-leaded 3.0 watt Zeners
provides voltage regulation selections with 5% tolerances from 3.9 to 200
volts in a DO-41 plastic package size. Other Zener voltage tolerances are
also available by changing the suffix number to the tolerance desired such
as 1, 2 3, or 4 for tighter tolerances or 10 for wider tolerance. These plastic
encapsulated Zeners have moisture classification of Level 1 with no dry
pack required and are also available in various military equivalent
screening levels by adding a prefix identifier as also described in the
Features section. They may be operated at high maximum dc currents or
full power rating with adequate heat. Microsemi also offers numerous other
Zener products to meet higher and lower power applications.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES APPLICATIONS / BENEFITS
• Zener voltage available 3.9 V to 200 V
• Standard voltage tolerances are plus/minus 5%
with a 5 suffix and 10 % with 10 suffix
identification
• Tight tolerances available in plus or minus 4%,
3%, 2% or 1% with 4, 3, 2, or 1 suffix respectively
• Options for screening in accordance with MIL-
PRF-19500 for JAN, JANTX, JANTXV, and JANS
are available by adding MQ, MX, MV, or MSP
prefixes respectively to part numbers.

NOTES: 1. Suffix 1 indicates +/-1% tolerance, suffix 2 indicates +/-2% tolerance, suffix 3 indicates +/-3% tolerance, suffix 4 indicates +/-4%
tolerance, suffix 5 indicates +/-5% tolerance. Suffix 10 indicates +/-10%, no suffix indicates +/-20%.
2. The VZ is measured by applying IZ 40 ms +/-10 ms prior to reading. Mounting contacts are located 3/8” to ½” from inside edge of
mounting clips. Ambient temperature, TA = 25oC (+8oC/-2oC).
3. The zener impedance is derived from the 60 cycle ac voltage resulting from an ac current having an rms value equal to 10%
of the dc zener current (IZT or IZK ) is superimposed on IZT or IZK.
4. Maximum Surge Current is a non-recurrent maximum peak reverse surge with a pulse width of 8.3 ms.
