Description/Features
The 30BQ015 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
