2STF2340
Low voltage fast-switching PNP power transistor
Features
■ Very low collector-emitter saturation voltage
■ High current gain characteristic
■ Fast switching speed
■ SOT-89 plastic package for surface mounting
circuits
Applications
■ LED

Description
The device in a PNP transistor 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 complementary NPN is the 2STF1340.
