STL73D

High voltage fast-switching NPN power transistor

Features

Application

Description

The device is manufactured using high voltage

multi-epitaxial planar technology for high

switching speeds and high voltage capability.

It uses a cellular emitter structure with planar

edge termination to enhance switching speeds

while maintaining the wide RBSOA.

The STL series is designed for use in compact

fluorescent lamps.
