TECHNICAL DATA SHEET
50 WATT ZENER DIODES
Qualified per MIL-PRF-19500/114
APPLICATIONS / BENEFITS
¾ Regulates voltage over a broad operating current and temperature range
¾ Standard voltage tolerances are +/- 5% with B suffix
¾ Consult factory for +/-10% with an A suffix, +/-20% with no suffix, +/-2% with a C suffix and +/-1% with a D
suffix respectively
¾ Reverse polarity available
¾ Nonsensitive to ESD per MIL-STD-750 Method 1020
¾ Inherently radiation hard as described in Microsemi MicroNote 050
MAXIMUM RATINGS
¾ Junction Temperatures: -65°C to +175°C
¾ Storage Temperatures: -65°C to +200°C
¾ DC Power Dissipation: 50 watts at TC < 75°C
¾ Power Derating: 0.5W/°C above 75°C
¾ Forward Voltage @ 10A: 1.5 Volts
¾ THERMAL RESISTANCE: 2.0°C/W maximum junction to base (1.5°C/W typical)
¾ Solder temperatures: 260°C for 10 s (max)
MECHANICAL AND PACKAGING
¾ CASE: Industry Standard TO-3 (TO-204AD), hermetically sealed, 0.052 inch diameter pins.
¾ FINISH: All external surfaces are corrosion resistant and terminal solderable.
¾ POLARITY: Standard Polarity units are connected anode to case. Reverse polarity (cathode to case) is
indicated by suffix R. In either example, both pins are common with one another as anode or cathode (see
circuit on last page).
¾ WEIGHT: 15 grams.
¾ MOUNTING HARDWARE: Consult factory for optional insulator and sheet metal screws
¾ See package dimensions on last page
