FEATURES

• 150 °C TJ operation

• 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

DESCRIPTION

The VS-20TQ... Schottky rectifier series has been optimized
for very low forward voltage drop, with moderate leakage.
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.
