2STF1550 - STMicroelectronics

2STF1550 Low voltage fast-switching NPN power bipolar transistors

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.
