Datasheet 2STF2550

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.

Very low collector-emitter saturation voltage

Fast switching speed

High current gain characteristic

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
