STL128D Datasheet, PDF (1/12 Pages) STMicroelectronics – Low spread of dynamic parameters

STL128D
High voltage fast-switching NPN power transistor
Features
■ High voltage capability
■ Low spread of dynamic parameters
■ Very high switching speed
■ Integrated antiparallel collector-emitter diode
Applications
■ Electronic ballast for fluorescent lighting
■ Flyback and forward single transistor low
power converters
Description
These devices are high voltage fast-switching
NPN power transistors. They are manufactured
using high voltage multi epitaxial planar
technology for high switching speeds and medium
voltage capability.
They use a cellular emitter structure with planar
edge termination to enhance switching speeds
while maintaining the wide RBSOA. The devices
are designed for use in lighting applications and
low cost switch-mode power supplies.
