STPS15SM80C

Power Schottky rectifier

Features

■ High junction temperature capability

■ Optimized trade-off between leakage current

and forward voltage drop

■ Low leakage current

■ Avalanche capability specified

■ Insulated package TO-220FPAB

– insulated voltage: 2000 V
– package capacitance: 45 pF

Description

This dual diode Schottky rectifier is suited for high
frequency switch mode power supply.

Packaged in TO-220AB, I
220FPAB, this device is particularly suited for use
in notebook, game station, LCD TV and desktop
adapters, providing these applications with a
good efficiency at both low and high load.
