BULD742C Datasheet, PDF (1/12 Pages) STMicroelectronics – High voltage fast-switching

BULD742C
High voltage fast-switching
NPN power transistor
Features
■ Low spread of dynamic parameters
■ High voltage capability
■ Minimum lot-to-lot spread for reliable operation
■ Very high switching speed
Applications
■ Electronic ballast for fluorescent lighting
■ Switch mode power supplies
Description
The device is manufactured using high voltage
Multi-Epitaxial Planar technology for high
switching speeds and high voltage capability.
Thanks to an increased intermediate layer, it has
an intrinsic ruggedness which enables the
transistor to withstand an high collector current
level during breakdown condition, without using
the transil protection usually necessary in typical
converters for lamp ballast.
