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.

• Internal solder bond construction
• Hermetically sealed (welded)
• Zener Voltage 3.9V to 200V.
• Also available in JAN, JANTX, and JANTXV
• Standard polarity is anode to case (stud) for
• Reverse polarity is cathode to case for 1N2970
• Consult factory for surface mount equivalents
• Junction Temperatures: -65
• Storage Temperatures: -65
• DC Power Dissipation: 10 Watts
• Power Derating: 80 mW/
• Forward Voltage @ 2.0 A: 1.5 Volts
• THERMAL RESISTANCE: 10
• Solder temperatures: 260

MICROSEMI’s
FEATURES
1N3993 thru 1N4000A
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.
