Compliant Switching Diode
Qualified per MIL-PRF-19500/116
JAN, JANTX, and
JANTXV
This 1N4148UB switc h ing/signal dio de features ceramic bodied construction for military grade
products per MIL-PRF-19500/116. This small low capacitance diode, with very fast switching
speeds, is featur ed in a sur f ac e mount UB package with various polarities available.
Microsemi also offers a variety of other switching/signal diodes.
