10 WATT ZENER DIODES

Qualified per MIL-PRF-19500/124

* JEDEC Registered Data.

** Not JEDEC Data.

† Have JAN and JANTX Qualifications to MIL-PRF-19500/124.

See further notes on following page.

NOTES:

1. 1N3993 - 1N4000 series: suffix A indicates +/-5% tolerance, no suffix indicates +/-10% tolerance. 1N2970

– 1N3015 series: suffix B indicates +/- 5% tolerance, suffix A indicates +/-10%, no suffix indicates +/-20%

tolerance. If tighter tolerance is required, consult factory.

2. The electrical characteristics are measured after allowing the device to stabilize for 90 seconds with 30oC

Base temperature.

3. The zener impedance (ZZT) 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 or IZK) is superimposed on IZT or IZK. When making

zener impedance measurements at the IZK test point, it may be necessary to insert a 60 Hz band pass filter

between the diode and voltmeter to avoid errors resulting from low level noise signals. A curve showing the

variation of zener impedance vs. zener current for three representative types is shown in Figures 2 and 3.

Also see Microsemi MicroNote 202.

4. These values of IZM may be exceeded in the case of individual diodes. The values shown are calculated for

the worst case that is a unit of +/-5% tolerance at the high voltage end of its tolerance range. Allowance has

also been made for the rise in zener voltage above VZT, which results from zener impedance and the increase

in junction temperature as power dissipation approaches 10 watts.
