TIP107 PNP Darlington POWER TRANS. 100V 8A

The TIP107 is a PNP Darlington power transistor designed for medium-power switching and linear amplification applications. Built into a robust TO-220 through-hole package , this transistor combines two cascaded transistors in a single device, delivering a very high current gain (hFE) of approximately 200 with minimal base drive — making it easy to control directly from a microcontroller or low-current logic circuit. With a collector-emitter breakdown voltage of 100V and a continuous collector current rating of 8A , the TIP107 is well suited for driving inductive and resistive loads such as DC motors, solenoids, relays, lamps, and high-power LEDs . The TO-220 package supports 80W of power dissipation when properly heatsinked, and tolerates junction temperatures up to 150°C , ensuring reliable operation in demanding industrial and consumer applications. The TIP107 is commonly paired with its NPN complement, the TIP102 , in complementary push-pull output stages for audio power amplifiers and H-bridge motor driver circuits. Its high gain also makes it an excellent choice for logic-level interfacing , where small signals from microcontrollers like Arduino or Raspberry Pi need to switch large loads.
