FEATURES

• Small foot print, surface mountable

• Low forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term
reliability

• Compliant to RoHS directive 2002/95/EC

• Designed and qualified for industrial level

DESCRIPTION

The 10BQ040PbF surface mount Schottky rectifier has
been designed for applications requiring low forward drop
and very small foot prints on PC boards. Typical applications
are in disk drives, switching power supplies, converters,
freewheeling diodes, battery charging, and reverse battery
protection.
