BULD741 Datasheet, PDF (1/11 Pages) STMicroelectronics – High voltage fast-switching NPN power transistor

BULD741
High voltage fast-switching NPN power transistor
Features
■ High voltage capability
■ Low spread of dynamic parameters
■ Minimum lot-to-lot spread for reliable operation
■ Very high switching speed
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.
Applications
■ Electronic ballast for fluorescent lighting
■ Switch mode power supplies.
