STL128DN Datasheet, PDF (1/14 Pages) STMicroelectronics – High voltage fast-switching NPN power transistor

STL128DN
High voltage fast-switching NPN power transistor
Features
■ High voltage capability
■ Low spread of dynamic parameters
■ Very high switching speed
■ Large RBSOA
■ Integrated antiparallel collector-emitter diode
Applications
■ Electronic ballast for fluorescent lighting
■ Flyback and forward single transistor low
power converters
Description
The device is manufactured using high voltage
multi epitaxial planar technology for high switching
speeds and medium voltage capability. It uses a
cellular emitter structure with planar edge
termination to enhance switching speeds while
maintaining the wide RBSOA. The device is
designed for use in lighting applications and low
cost switch-mode power supplies.
