Schottky Rectifier, 1.0 A

10BQ015PbF

Vishay High Power Products

FEATURES

• 125 °C TJ operation (VR < 5 V)

• Optimized for OR-ing applications

• Ultralow forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term

reliability

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Lead (Pb)-free (“PbF” suffix)

• Designed and qualified for industrial level

DESCRIPTION

The 10BQ015PbF surface mount Schottky rectifier has

been designed for applications requiring low forward drop

and very small foot prints on PC boards. The proprietary

barrier technology allows for reliable operation up to 125 °C

junction temperature. Typical applications are in disk drives,

switching power supplies, converters, freewheeling diodes,

battery charging, and reverse battery protection.
