1N3994 General 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.

1N3994 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 JANTXVprefixes 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
1N3994 Typical Application
• Regulates voltage over a broad operating current and temperature range
• Standard voltage tolerances are +/- 5% with 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 1020
• Inherently radiation hard as described in Microsemi MicroNote 050
