Description
The 2STF1550 and 2STN1550 are NPN 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.

General 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
■ In compliance with the 2002/93/EC European Directive

APPLICATIONs
■ Emergency lighting
■ LED
■ Motherboard & Hard Disk drive
■ Mobile equipment
■ Battery charger
■ Voltage regulation
