Description
TIP147 PNP Darlington Transistor – 100V 10A TO-220
The TIP147 PNP Darlington Transistor is a high-power bipolar transistor designed for applications requiring high current gain and robust switching performance. With a collector-emitter voltage rating of 100V and a continuous collector current of 10A, the TIP147 is well suited for medium to high-power electronic circuits. Its Darlington configuration provides very high current gain, allowing efficient control of large loads with minimal base drive current. Supplied in a rugged TO-220 through-hole package, this transistor supports easy PCB mounting and effective heatsink attachment. The TIP147 is widely used in power amplifiers, motor control circuits, relay drivers, linear regulators, SMPS stages, and industrial power electronics where reliability and thermal stability are essential.
