1 / 4 page 50 Watt Zener Diodes SCOTTSD A L E DIVISION 1N2804 thru 1N2846B and 1N4557 thru 1N4564B DESCRIPTION APPEARANCE These high power 50 W Zener diodes represented by the JEDEC registered 1N2804 thru 1N2846B and 1N4557 thru 1N4564B 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 50 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. TO-3 (TO-204AD) IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • JEDEC registered 1N2804 thru 1N2846B and 1N4557 thru 1N4564B • Internal solder bond construction • Hermetically sealed (welded) • Zener Voltage 3.9V to 200V. • Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/114 by adding the JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening; (e.g. JANTX1N2804B, etc. • Standard polarity is anode to case • Reverse polarity with cathode to case by designating R suffix in part number, e.g. 1N2804RB, 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% 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: 50 watts at TC < 75 oC • Power Derating: 0.5W/ oC above 75oC • Forward Voltage @ 10 A: 1.5 Volts • THERMAL RESISTANCE: 2.0 oC/W maximum junction to base (1.5 oC/W typical) • Solder temperatures: 260 oC for 10 s (max) • CASE: Industry Standard TO-3 (TO-204AD), hermetically sealed, 0.052 inch diameter pins. • FINISH: All external surfaces are corrosion resistant and terminal solderable. • POLARITY: Standard Polarity units are connected anode to case.
