1 / 4 page 10 WATT ZENER DIODES SCOTTSD A L E DIVISION 1N2970 thru 1N3015B and 1N3993 thru 1N4000A DESCRIPTION APPEARANCE 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) IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • 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 • Regulates voltage over a broad operating current and temperature range • Standard voltage tolerances are +/- 5% with B 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 MAXIMUM RATINGS MECHANICAL AND PACKAGING • Junction Temperatures: -65 oC to +175oC • Storage Temperatures: -65 oC to +200oC • DC Power Dissipation: 10 Watts • Power Derating: 80 mW/ oC above 50oC • Forward Voltage @ 2.0 A: 1.5 Volts • THERMAL RESISTANCE: 10 oC/W (typical) junction to case (stud) • Solder temperatures: 260 oC for 10 s (max) • CASE: Industry Standard DO-4, (DO-203AA), 7/16” Hex, stud with 10-32 threads, welded, hermetically sealed metal and glass • FINISH: All external surfaces are corrosion resistant and terminal solderable • POLARITY: 1N3993 – 1N4000: Std. Polarity is cathode to stud. Reverse polarity (anode to stud) indicated by suffix “R” 1N2970 – 1N3015: Std. Polarity is anode to stud. Reverse polarity indicated by suffix “R” • WEIGHT: 7.5 grams • MOUNTING HARDWARE: Consult factory for optional insulator, bushing solder terminal, washers, and nut • See package dimension on last page Microsemi Scottsdale Division 8700 E.
