STPS30L45C

Low drop power Schottky rectifier

Features

■ low forward voltage drop meaning very small

conduction losses

■ low switching losses allowing high frequency

operation

■ low thermal resistance

■ avalanche rated

■ insulated package TO-220FPAB:

– insulating voltage = 2000 V DC
– capacitance = 45 pF

■ avalanche capability specified

Description

Dual center tap Schottky rectifier suited for
switched mode power supplies and high
frequency DC to DC converters.

Packaged in TO-247, TO-220AB, TO-220FPAB,
