The NTE274 is an NPN silicon Darlington transistor in a TO66 case, designed for general-purpose amplifier and switching applications. It has a continuous collector current rating of 4 A and a collector-emitter sustaining voltage of 80 V minimum. The device features a typical DC current gain of 3000 at 2 A collector current and a maximum collector-emitter saturation voltage of 2 V at 2 A. Power dissipation is rated at 50 W at 25°C, derating at 0.286 W/°C above 25°C. The operating junction and storage temperature range is -65°C to +200°C. Thermal resistance junction-to-case is 3.5°C/W. The case dimensions are 24.3 mm in length, with a base diameter of 9.14 mm and collector/emitter terminal spacing of 5.08 mm. Built-in base-emitter shunt resistors are incorporated in monolithic construction.
