DESCRIPTION These “standard recovery” high voltage rectifier diode series are military qualified to MIL-PRF-19500/279 for the 1N3644 thru 1N3647. Others such as the 1N5181 thru 1N5184 meet or exceed requirements of MIL-PRF-19500/389. They are ideal for high-reliability where a failure cannot be tolerated for high voltage applications. FEATURES • JEDEC registered 1N3643 thru 1N3647, 1N4254 thru 1N4257, and 1N5181 thru 1N5187 series • Voidless Hermetically Sealed Glass Package • Triple Layer Passivation • Internal “Category I” Metallurgical bonds • Lowest Reverse Leakage Available • Lowest Thermal Resistance Available • Absolute High Voltage / High Temperature Stability • 1N5181 thru 1N5184 meet or exceed requirements of MIL-S-19500/389 • 1N3644 thru 1N3647 JAN, JANTX types available per MIL-S19500/279 • Surface mount equivalents also available in a square end-cap MELF configuration with “SM” suffix APPLICATIONS / BENEFITS • High voltage standard recovery rectifiers 1000 to 10,000 V • Military and other high-reliability applications • Applications include bridges, half-bridges, catch diodes, voltage multipliers, X-ray machines, power supplies, transmitters, and radar equipment • High forward surge current capability • Extremely robust construction • Low thermal resistance • Inherently radiation hard as described in Microsemi MicroNote 050
