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
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 MILPRF-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.
