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.
