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 axial-leaded packages for thru-hole mounting (see separate
data sheet for 1N6626 thru 1N6631). 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.
Package “E”
or D-5B
