TO-220AB

Features

• ST patented rectifier process

• Stable leakage current over reverse voltage

• Low forward voltage drop

• High frequency operation

•ECOPACK®2 compliant

Applications

• Adapter

• Gaming console power supply

• Battery charger

• DC / DC converter

Description

This single rectifier is based on a proprietary technology, enabling to achieve the best

in class VF/IR for a given silicon surface.

Packaged in TO-220AB, TO-220FPAB and D2PAK, the FERD40H100S is optimized

for use in confined applications where both efficiency and thermal performance are

key. With a lower dependency of leakage current (IR) and forward voltage (VF) in

function of temperature, the thermal runaway risk is reduced. It is highly

recommended to be used in adapters and chargers.
