DESCRIPTION
These high power 10 W Zener diodes represented by the JEDEC registered
1N2970 thru 1N3015B and 1N3993 thru 1N4000A series provide voltage
regulation in a selection over a 3.9 V to 200 V broad range of voltages. They may
be operated up to 10 W with adequate mounting and heat sinking with their low
thermal resistance. These Zeners are also available in JAN, JANTX, JANTXV
military qualifications. Microsemi also offers numerous other Zener products to
meet higher and lower power applications.
DO-4 (DO-203AA)
FEATURES
¾ JEDEC registered 1N2970 thru 1N3015B and 1N3993 thru 1N4000A
¾ Internal solder bond construction
¾ Hermetically sealed (welded)
¾ Zener Voltage 3.9V to 200V.
¾ Also available in JAN, JANTX, and JANTXV qualifications per MIL-
PRF-19500/124 by adding the JAN, JANTX, or JANTXV prefixes to part
numbers for desired level of screening; (e.g. JANTX1N2970B,
JANTXV1N3996A, etc.
¾ Standard polarity is anode to case (stud) for 1N2970 thru 1N3015B and
cathode to case for 1N3993 thru 1N4000A
¾ Reverse polarity is cathode to case for 1N2970 thru 1N3015B and anode to
case for 1N3993 thru 1N4000A by designating R suffix, e.g. 1N2970RB,
1N3993RA, etc.
¾ Consult factory for surface mount equivalents

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.
