Schottky Rectifier, 2 A
VS-20BQ030PbF
Vishay High Power Products
FEATURES
• Small foot print, surface mountable
• Very low forward voltage drop
• High frequency operation
• Guard ring for enhanced ruggedness and long term
reliability
• Meets MSL level 1, per J-STD-020, LF maximum peak of
260 °C
• Compliant to RoHS directive 2002/95/EC
• Designed and qualified for industrial level
DESCRIPTION
The VS-20BQ030PbF surface mount Schottky rectifier has
been designed for applications requiring low forward drop
and small foot prints on PC boards. Typical applications are
in disk drives, switching power supplies, converters,
freewheeling diodes, battery charging, and reverse battery
protection.
