VOIDLESS HERMETICALLY SEALED STANDARD

RECOVERY GLASS RECTIFIERS

Qualified to MIL-PRF-19500/420

Qualified Levels:

JAN, JANTX, JANTXV

and JANS

DESCRIPTION

This “standard recovery” rectifier diode series is military qualified and is ideal for high-reliability

applications where a failure cannot be tolerated. These industry-recognized 5.0 amp rated

rectifiers for working peak reverse voltages from 200 to 1000 volts are hermetically sealed

with voidless-glass construction using an internal “Category 1” metallurgical bond. These

devices are also available in surface mount MELF package configurations. Microsemi also

offers numerous other rectifier products to meet higher and lower current ratings with various

recovery time speed requirements including fast and ultrafast device types in both through-

hole and surface mount packages.
