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
