DESCRIPTION

APPEARANCE

This “standard recovery” rectifier diode is military qualified to MIL-PRF-19500/587 and

is ideal for high-reliability applications where a failure cannot be tolerated. These

industry-recognized 500 mA rated rectifiers for working peak reverse voltages from 225

to 600 volts are hermetically sealed with void-less-glass construction using an internal

“Category I” metallurgical bond. The surface mount MELF package configurations are

also available by adding a “US” suffix (see separate data sheet for 1N6661US thru

1N6663US). 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.
