TIP102 Darlington Transistor (100V, 8A)

Overview

The TIP102 is a high-gain NPN Darlington transistor designed for demanding power-switching applications. With a collector-emitter breakdown voltage of 100V and a continuous collector current rating of 8A, it provides robust performance for controlling high-power loads. Its Darlington configuration delivers exceptionally high current gain, allowing low-current control signals to switch substantial loads, making it a staple component for motor drivers, solenoid actuators, and power supply circuits.
