Schottky Rectifier, 2 x 20 A

VS-40CTQ045SPbF, VS-40CTQ045-1PbF

Vishay High Power Products

FEATURES

• 150 °C T

operation

• Center tap configuration

• Very low forward voltage drop

• High frequency operation

• High purity, high temperature epoxy

encapsulation for enhanced mechanical

strength and moisture resistance

• Guard ring for enhanced ruggedness and long

term reliability

• Meets MSL level 1, per J-STD-020, LF maximum peak of

260 °C

• Halogen-free according to IEC 61249-2-21 definition

• Compliant to RoHS directive 2002/95/EC

• AEC-Q101 qualified

DESCRIPTION

This center tap Schottky rectifier has been optimized for

very low forward voltage drop, with moderate leakage. The

proprietary barrier technology allows for reliable operation

up to 150 °C junction temperature. Typical applications are

in switching power supplies, converters, freewheeling

diodes, and reverse battery protection.
