DESCRIPTION
APPEARANCE
This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-
19500/585 and is ideal for high-reliability applications where a failure cannot be
tolerated. These industry-recognized 1.5 to 2.0 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 surface mount MELF package configurations by adding a “US”
suffix (see separate data sheet for 1N6620US thru 1N6625US). Microsemi also
offers numerous other rectifier products to meet higher and lower current ratings
with various recovery time speed requirements including standard, fast and ultrafast
device types in both through-hole and surface mount packages.

Average Rectified Forward Current (IO) at TL= +55oC
(L=.375 inch from body):
1N6620 thru 1N6622: 2.0 Amps
1N6623 thru 1N6625: 1.5 Amps
(Derate linearly at 0.833%/oC for TL> +55oC)
Average Rectified Forward Current (IO) at TA=25oC:
1N6620 thru 1N6622: 1.2 Amps
See package dimensions on last page
•
1N6623 thru 1N6625: 1.0 Amp
(Derate linearly at 0.67%/ oC for TA>+25oC. This IO
rating is typical for PC boards where thermal
resistance from mounting point to ambient is
sufficiently controlled where TJ(max) is not exceeded.)
