USD545 [Microchip]

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 Microchip 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.
