2N3772 Description

Short technical summary and product information.

The 2N3772 is a high-power NPN silicon transistor designed for linear amplifiers, series pass regulators, and inductive switching applications. It features a maximum collector-emitter voltage (VCEO) of 60V, with collector-emitter sustaining voltage (VCEO(sus)) also rated at 60V minimum. The device can handle continuous collector current up to 20A and peak currents up to 30A. Base current ratings are 5A continuous and 15A peak.

 

Power dissipation is 150W at a case temperature of 25°C, derating at 0.855W/°C above 25°C. The operating junction temperature range is -65°C to +200°C, with a thermal resistance junction-to-case of 1.17°C/W. DC current gain (hFE) is specified as 15-60 at IC=10A and VCE=4V, and minimum 5 at higher currents. Collector-emitter saturation voltage (VCE(sat)) is 4V maximum at IC=20A and IB=4A. The transition frequency (fT) is 200kHz.

 

The transistor is housed in a TO-204AA (TO-3) package and is intended for chassis mount installation. It is suitable for a variety of power control and switching circuits where high current and power handling are required.
