Schottky Rectifier, 2 x 20 A

MBRB4045CTPbF/MBR4045CT-1PbF

Vishay High Power Products

FEATURES

• 150 °C TJ operation

• Low forward voltage drop

• High frequency operation

• Center tap TO-220, D2PAK and TO-262

packages

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Guard ring for enhanced ruggedness and long term

reliability

• Lead (Pb)-free (“PbF” suffix)

• Designed and qualified for Q101 level

DESCRIPTION

The 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.
