The onsemi TIP121TU is an NPN Darlington bipolar transistor designed for power switching applications. This through-hole component, housed in a TO-220-3 package, features a continuous collector current capability of 5A and a maximum collector-emitter breakdown voltage of 80V. With a minimum DC current gain (hFE) of 1000 at 3A and 3V, it offers significant amplification for driving loads. The device is rated for a maximum power dissipation of 2W and operates at temperatures up to 150°C (TJ). Its high saturation voltage (Vce Sat) of 4V at 20mA and 5A is characteristic of Darlington configurations. This component is commonly employed in power supply regulation, motor control, and general-purpose amplification circuits across various industrial and consumer electronics sectors.
