onsemi Bipolar Transistor, Npn, 60V To-220; Transistor Polarity Onsemi TIP120G.

The TIP120G is an NPN silicon Darlington transistor in a TO-220AB package, designed for general-purpose amplifier and low-speed switching applications. It has a collector-emitter voltage rating of 60 Vdc, a continuous collector current of 5.0 Adc, and a total power dissipation of 65 W at 25°C case temperature. The device features a minimum DC current gain of 1000 at 3.0 Adc collector current, a collector-emitter saturation voltage of 2.0 Vdc maximum at 3.0 Adc, and a base-emitter on voltage of 2.5 Vdc maximum. It includes built-in base-emitter shunt resistors and is Pb-free. The thermal resistance from junction to case is 1.92 °C/W. The TO-220AB package has three pins: base, collector, and emitter, with the collector connected to both pin 2 and pin 4.
