2STF1525

Low voltage high performance NPN power transistor

Features

■ Very low collector-emitter saturation voltage

■ High current gain characteristic

■ Fast switching speed

Applications

■ Emergency lighting

■ LED drive

■ Motherboard and hard disk drive

■ Mobile equipment

■ DC-DC converter, voltage regulation

Description

The device is a NPN transistor manufactured

using new “PB-HCD” (power bipolar high current

density) technology. The resulting transistor

shows exceptional high gain performances

coupled with very low saturation voltage.
