The BD679AS is an NPN Darlington transistor manufactured by ON Semiconductor. It is designed for medium-power switching and amplification applications. Key electrical specifications include a collector-emitter voltage (Vceo) of 80V, a continuous collector current (Ic) of 4A, and a power dissipation (Pd) of 40W. The device offers a minimum DC current gain (hFE) of 750 when tested at Ic=2A and Vce=3V, with a maximum collector-emitter saturation voltage (Vce(sat)) of 2.8V at Ib=40mA and Ic=2A. The transistor is housed in a through-hole TO-126-3 package (also compatible with TO-225AA), making it suitable for PCB mounting. The operating junction temperature is rated up to 150°C. This Darlington configuration provides high current gain, reducing the base drive requirement in switching and linear circuits. Typical applications include relay drivers, solenoid drivers, motor controllers, and audio output stages. The part is listed as RoHS3 compliant and has an MSL of 1 (unlimited).
