2STF2340

2STN2340

Low voltage fast-switching PNP power 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.
