DESCRIPTION
APPEARANCE
This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-
19500/590 and is ideal for high-reliability applications where a failure cannot be
tolerated. These industry-recognized 2.0 to 4.0 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 1N6626US thru 1N6631US). 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= +75oC
(L=.375 inch from body):
1N6626 thru 1N6628
1N6629 thru 1N6631
2.3 A
1.8 A
See package dimensions on last page
(Derate IO linearly at 1.0%/oC for TL> +75oC)
•
Average Rectified Forward Current (IO) at TA=25oC:
1N6626 thru 1N6628
1N6629 thru 1N6631
1.75 A
1.40 A
(Derate IO linearly at 0.80%/ 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. See MIL-PRF-19500/590)
