Rectron Semiconductor Inc. MOSFET TTIP125

The TTIP125 is a PNP Darlington power transistor in a TO-220 package with a maximum collector-emitter voltage of 60 V, a continuous collector current of 4 A, and a total power dissipation of 2 W at 25°C ambient temperature. The device has a minimum DC current gain of 1000 at 2 A collector current and 2 V collector-emitter voltage, and a maximum collector-emitter saturation voltage of 2 V at 2 A collector current and 21 mA base current. The junction temperature rating is 150°C, and it features a thermal resistance from junction to case of 1.781 °C/W. Storage temperature ranges from -55°C to 150°C.
