2N3773 Description

Short technical summary and product information.

The 2N3773 is a high-power NPN bipolar junction transistor designed for linear and switching applications. It features a maximum collector-emitter voltage (VCEO) of 140V, a continuous collector current rating of 16A, and a peak current capability of 30A under pulse conditions. The device offers a minimum DC current gain (hFE) of 15 at 8A collector current and 4V VCE, with a low collector-emitter saturation voltage of 1.4V maximum at 8A.

 

Power dissipation is rated at 150W at 25°C case temperature, with a derating factor of 0.855 W/°C above 25°C. The operating junction temperature range is from -65°C to 200°C, and the thermal resistance junction-to-case is 1.17°C/W. The transistor is supplied in a TO-204AA (TO-3) through-hole metal package, suitable for mounting on heatsinks.

 

Typical applications include high-power audio amplifiers, disk head positioners, linear power supplies, and power switching circuits such as relay or solenoid drivers, DC-DC converters, and inverters. The datasheet indicates the part is Pb-Free and RoHS3 compliant (unverified).
