Schottky Rectifier, 2 x 40 A

80CPQ020PbF

Vishay High Power Products

FEATURES

• Center tap configuration

• Optimized for 3.3 V application

• Ultralow forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term

reliability

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Lead (Pb)-free (“PbF” suffix)

• Designed and qualified for industrial level

DESCRIPTION

This center tap Schottky rectifier has been optimized for

ultralow forward voltage drop specifically for 3.3 V output

power supplies. The proprietary barrier technology allows for

reliable operation up to 150 °C junction temperature. Typical

applications are in parallel switching power supplies,

converters, reverse battery protection, and redundant power

subsystems.
