te PDESCRIPTION
The BUF420M is manufactured using High
leVoltage Multi Epitaxial Planar technology for high
soswitching speeds and high voltage capacity. It
buses a Cellular Emitter structure with planar edge
Otermination to enhance switching speeds while
-maintaining a wide RBSOA.
)The BUF series is designed for use in
t(shigh-frequency power supplies and motor control
capplications.
