BULK128_08 Datasheet, PDF (1/11 Pages) STMicroelectronics – High voltage fast-switching NPN power transistor

BULK128
High voltage fast-switching
NPN power transistor
Features
■ High voltage capability
■ Minimum lot-to-lot spread for reliable operation
■ Very high switching speed
Applications
■ Electronic ballast for fluorescent lighting
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.
