APPEARANCE
DESCRIPTION
This series of 75 Amp rated average forward current series of Schottky
barrier power rectifiers in 20 through 50 volt selections 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
with applicable heat sinking for peak repetitive forward currents up to 150
Amps at 50% duty cycle. This rugged DO-5 hermetically sealed design
absorbs stress that can otherwise damage glass-to-metal seals during
installation and operation. It is also available in a flexible top lead as
described herein.
