onsemi Single Bipolar Transistors TIP127

The TIP127 is a PNP epitaxial Darlington transistor in a TO-220 3-lead package, designed for medium power linear switching applications. It has a collector-emitter voltage rating of -100 V, a collector current rating of -5 A (DC) and -8 A (pulse), and a collector dissipation of 65 W at 25°C. The device features a minimum DC current gain of 1000 at -3 A collector current and a collector-emitter saturation voltage of -4 V at -5 A collector current and -20 mA base current. The base-emitter on-voltage is -2.5 V at -3 A collector current. The package is compliant with JEDEC variation AB, and the transistor is not designed for use in life support systems.
