The TIP102G is an NPN Darlington power transistor designed for general-purpose amplification and low-speed switching. It features a collector-emitter voltage of 100 Vdc and a continuous collector current rating of 8.0 A, with a peak current of 15 A. The device is characterized by a high DC current gain, typically 2500 at a collector current of 4.0 A, and a low collector-emitter saturation voltage of 2.5 V at 8.0 A. With a total power dissipation of 80 W and a wide operating temperature range, this transistor is well-suited for power regulation, driver circuits, and audio amplifiers.
