DESCRIPTION

The BUF420M is manufactured using High

Voltage Multi Epitaxial 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.
