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.
