1N4446-1 – 1N4449-1
Available
Computer Switching Diode
DESCRIPTION
These popular 1N4149, 1N4151, 1N4154 and 1N4446 – 1N4449 series of JEDEC registered
switching/signal diodes are available with internal metallurgical bonded construction. These
small low capacitance diodes, with very fast switching speeds, are hermetically sealed and
bonded into a double-plug DO-35 package. They may be used in a variety of fast switching
applications including computers and peripheral equipment such as magnetic cores, thin-film
memories, plated-wire memories, as well as decoding or encoding applications, etc.
Microsemi also offers a variety of other switching/signal diodes.
