Schottky Rectifier, 20 A

20L15TS

Vishay High Power Products

FEATURES

• Single diode configuration

• Optimized for OR-ing applications

• Ultra low forward voltage drop

• Guard ring for enhanced ruggedness and long term

reliability

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Designed and qualified for Q101 level

DESCRIPTION

The Schottky rectifier module has been optimized for ultra

low forward voltage drop specifically for the OR-ing of

parallel power supplies. The proprietary barrier technology

allows for reliable operation up to 125 °C junction

temperature. Typical applications are in parallel switching

power supplies, converters, reverse battery protection, and

redundant power subsystems.
