DESCRIPTION
APPEARANCE
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 APPLICATIONS / BENEFITS
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
current and temperature range
Standard voltage tolerances are +/- 5% with B
suffix, +/-10% with an A suffix, and +/-20% with
no suffix
Consult factory for +/-2% or +/-1% voltage
tolerance with a C or D suffix respectively
Reverse polarity available
Nonsensitive to ESD per MIL-STD-750 Method
