Characteristics Values Units
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, free-wheeling diodes,
battery charging, and reverse battery protection.
125°C TJ operation (VR < 5V)
Optimized for OR-ing applications
Ultra low 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-Free ("PbF" suffix)
