2STF2340

2STF2340 2STN2340 Low voltage fast-switching PNP power transistors Features ■ Very low collector-emitter saturation voltage ■ High current gain characteristic ■ Fast switching speed Applications ■ LED ■ Motherboard & hard disk drive ■ Mobile equipment ■ DC-DC converter Description The devices are PNP transistors 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 2STF2340 complementary PNP is the 2STF1340. 4 4 3 2 1 3 2 1 SOT-89 SOT-223 Figure 1.
