High voltage fast-switching NPN Power Transistor

General features

■

NPN Transistor

■

High voltage capability

■

Low spread of dynamic parameters

■

Minimum lot-to-lot spread for reliable operation

■

Very high switching speed

■

In compliance with the 2002/93/EC European

Directive

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.

Applications

■

Electronic ballast for fluorescent lighting

■

Dedicated for PFC solution in HF ballast half-

bridge voltage fed
