TIP142 Transistor NPN Power Darlington Transistor TO-247 100V 10A ST TIP142

Product Overview:

A through-hole NPN silicon Darlington power transistor housed in a robust TO-247 plastic package. Featuring a monolithic Darlington configuration with integrated base-emitter shunt resistors and an anti-parallel collector-emitter diode, it delivers exceptionally high current gain ($h_{FE}$). This makes it exceptionally well-suited for high-current applications demanding direct control from low-power circuitry, such as linear audio amplifiers, motor controllers, solenoids, and switching regulators. It frequently serves as the complementary NPN pair to the TIP147 PNP Darlington transistor.
