STL72

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)

Description TO-92 TO-92AP
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 Figure 1. Internal schematic diagram
termination to enhance switching speeds while
maintaining the wide RBSOA.
The STL series is designed for use in compact
fluorescent lamps.
