Datasheet stl72 Datasheet

High voltage fast-switching NPN power transistor

Features

■ High voltage capability

■ Low spread of dynamic parameters

■ Very high switching speed

Application

■ Compact fluorescent lamps (CFLs)

STL72

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.
