What is TIP142 used for?
The TIP142 is well suited for high-current switching and driving applications such as DC motor control, relay and solenoid drivers, and power amplifier output stages. Its integrated base-emitter resistor and protection diode simplify inductive load switching in industrial control and power supply circuits. The 10 A, 100 V rating makes it a good fit for medium-power linear and switching regulator designs.
