IMPORTANT: For the most current data, consult MICROSEMI’s website:

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.
