Product Description

The BUF420AW is a 450V High Voltage Fast Switching NPN Power Transistor manufactured using high voltage Multiepitaxial planar technology for high switching speeds and high voltage capacity. It uses a cellular emitter structure with planar edge termination to enhance switching speeds while maintaining a wide RBSOA. The BUF series is designed for use in high frequency power supplies and motor control applications. Fast switching times and very low saturation voltage resulting in reduced switching and conduction losses.
High voltage capability
Very high switching speed
Minimum lot-to-lot spread for reliable operation
Low base drive requirements
Well-controlled hFE parameter for increased reliability
