This is a high voltage fast switching NPN power transistor manufactured in multi epitaxial planar technology. It uses a cellular emitter structure with planar edge termination to enhance switching speeds while maintaining a wide RBSOA.
Thanks to an increased intermediate layer, it has an intrinsic ruggedness which enables the transistor to withstand a high collector current level during breakdown condition, without using the Transil™ protection usually necessary in typical converters for lamp ballast.

High voltage capability
Very high switching speed
Applications
Four lamp electronic ballast for:
120 V mains in push-pull configuration
277 V mains in half bridge current feed configuration
