2STF2340 2STN2340 Low voltage fast-switching PNP power transistors Features Very low collector-emitter saturation voltage High current gain characteristic 4 4 Fast switching speed 3 3 2 2 Applications 1 1 LED Motherboard & hard disk drive SOT-89 SOT-223 Mobile equipment DC-DC converter Figure 1. Internal schematic diagram 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. Table 1.
