DESCRIPTION
APPEARANCE
This “standard recovery” surface mount rectifier diode series is military qualified to
MIL-PRF-19500/420 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 I” metallurgical bond. These devices are
also available in axial-leaded packages for thru-hole mounting (see separate data
sheet for 1N5550 thru 1N5554).
Microsemi also offers numerous other rectifier
products to meet higher and lower current ratings with various recovery time speeds.

NOTE 1: Derate linearly at 66.6 mA/C above TEC = 100C. An IO of up to 6 Amps is allowable provided that appropriate heat sinking or
forced air cooling maintains the junction temperature at or below +200C.
NOTE 2: Derate linearly at 25 mA/C above TA = 55C. This rating is typical for PC boards where thermal resistance from mounting point to
ambient is sufficient controlled where TJ(MAX) rating is not exceeded.
