Glass Axial Switching Diode

Qualified per MIL-PRF-19500/116

Qualified Levels:

JAN, JANTX, and

JANTXV

DESCRIPTION

This popular 1N4148-1 JEDEC registered switching/signal diode features internal

metallurgical bonded construction for military grade products per MIL-PRF-19500/116. This

small low capacitance diode, with very fast switching speeds, is hermetically sealed and

bonded into a double-plug DO-35 package. It may be used in a variety of very high speed

applications including switchers, detectors, transient OR'ing, logic arrays, blocking, as well as

low-capacitance steering diodes, etc. Microsemi also offers a variety of other switching/signal

diodes.
