transistors
Features
■ Very low collector-emitter saturation voltage ■ High current gain characteristic ■ Fast switching speed
Applications
■ LED ■ Motherboard & hard disk drive ■ Mobile equipment ■ DC-DC converter
Description
The devices are
PNP transistors manufactured using new “PB-HDC” (power bipolar high density current) technology. The resulting
transistor shows exceptional high gain performances coupled with very low saturation voltage. The 2STF2340 complementary
PNP is the 2STF1340.
