Schottky Rectifier, 2 x 10 A

MBRB20..CT/MBR20..CT-1

Vishay High Power Products

FEATURES

• 150 °C TJ operation

• Center tap D2PAK and TO-262 packages

• 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

• Designed and qualified for Q101 level

DESCRIPTION

This center tap Schottky rectifier has been optimized for low

reverse leakage at high temperature. 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.
