MBRB20...CTPbF, MBR20...CT-1PbF
Vishay High Power Products
FEATURES
• 150 °C TJ operation
• Low forward voltage drop
• High frequency operation
• Center tap 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
• Compliant to RoHS directive 2002/95/EC
• Halogen-free according to IEC 61249-2-21 definition

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.
