Description

The BUF420 and BUF420M are manufactured using High Voltage Multi Epitaxial Planar technology for high switching speeds and high voltage capacity. They use a Cellular Emitter structure with planar edge termination to enhance switching speeds while maintaining a wide RBSOA.

The BUF series BUF420 is designed for use in high-frequency power supplies and motor control applications.
