1N2970 thru 1N3015B
and 1N3993 thru 1N4000A
10 WATT ZENER DIODES
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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
APPEARANCE
DO-4
(DO-203AA)
FEATURES
JEDEC registered 1N2970 thru 1N3015B and
1N3993 thru 1N4000A
Internal solder bond construction
Hermetically sealed (welded)
Zener Voltage 3.9V to 200V.
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.
Standard polarity is anode to case (stud) for
1N2970 thru 1N3015B and cathode to case for
1N3993 thru 1N4000A
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.
Consult factory for surface mount equivalents

NOTES: 1.

4.
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.
The electrical characteristics are measured after allowing the device to stabilize for 90 seconds with 30oC Base temperature.
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.
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.
