• Center tap TO-220 package
• 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

DESCRIPTION
The VS-MBR(B)15... 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.
