■ Very low collector to emitter saturation voltage
■ DC current gain, h
FE
> 100
■ 3 A continuous collector current
■ 40 V breakdown voltage V
(BR)CER
Applications
■ Power management in portable equipment

Description
The devices are manufactured in low voltage PNP
planar technology by using a “Base Island” layout.
The resulting transistor shows exceptional high
gain performance coupled with very low
saturation voltage. The STX790AG-AP is supplied
using halogen-free molding compound.
