Description

The 2STF2550 and 2STN2550 are PNP

transistors 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.

Features

■ Very low collector-emitter saturation voltage

■ High current gain characteristic

■ Fast switching speed

■ Surface mounting devices in medium power

SOT-89 and SOT-223 packages

Applications

■ Emergency lighting

■ LED

■ Motherboard and hard disk drive

■ Mobile equipment

■ Battery charger

■ Voltage regulation
