2STR1215 Low voltage fast-switching NPN power transistor Features Very low collector-emitter saturation voltage High current gain characteristic 3 Fast switching speed Miniature SOT-23 plastic package for surface 2 mounting circuits 1 Applications SOT-23 LED Battery charger Voltage and relay driver Voltage regulation Figure 1. Internal schematic diagram Description The 2STR1215 is a NPN transistor 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. The complementary PNP is the 2STR2215. Table 1.
