DESCRIPTION

These highpower10 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 beoperated 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.

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
