Description:
This series of Schottky barrier power rectifiers is ideally suited for
output rectifiers and catch diodes in low voltage power supplies. The
Microsemi high conductivity design, using a heavy copper top post
and 4 point crimp, ensures cool thermal operation and low dynamic
impedance. Rugged design absorbs stress that can damage glass-
to-metal seal during installation and use.
