FAST RECOVERY RECTIFIERS
Qualified per MIL-PRF-19500/304*
DESCRIPTION
This 1N3889 – 1N3891 and 1N3893 family of rectifier devices are suitable for applications in
DC power supplies, inverters, converters, choppers and ultrasonic systems as well as other
applications. It can also be used as a free-wheeling diode. They are military qualified up to a
JANTXV level on select part numbers and they are available in both standard and reverse
polarities. Microsemi also offers numerous other products to meet higher and lower power
voltage regulation applications.
