STPS61L60C
Power Schottky rectifier
Features
■High current capability
■Avalanche rated
■Low forward voltage drop current
■High frequency operation
Description
This dual center tap schottky rectifier is suited for
high frequency switch mode power supplies.
Packaged in TO-247 and TO-220AB, this device
provides desktop SMPS designers with a low
forward voltage drop device, and reduced leakage
current, with the objective of making the
application compliant with environmental care
standards, or suitable for 80+ requirements.
