TIP127 PNP Darlington Transistor – 5A 100V

The TIP127 is a high-current PNP Darlington bipolar junction transistor designed for power switching and amplification applications. It integrates two PNP transistors in a Darlington configuration, providing very high DC current gain (hFE ? 1000) while requiring minimal base drive. With a collector current capability of up to 5A and collector-emitter voltage up to 100V, the TIP127 is ideal for motor drivers, relay control, solenoid drivers, and general-purpose low-voltage power switching. Its TO-220 package allows effective heat dissipation, making it suitable for medium- to high-power control systems.
