VS-MBRB4045CTPbF, VS-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
• 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

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.
