Quality Control: Learn More
The onsemi BD679ASTU is an NPN Darlington bipolar transistor designed for high-current switching and amplification applications. This component offers a continuous collector current (Ic) of up to 4A and a collector-emitter breakdown voltage (Vce) of 80V. Featuring a minimum DC current gain (hFE) of 750 at 2A and 3V, and a saturation voltage (Vce Sat) of 2.8V at 40mA and 2A, it ensures efficient operation. With a maximum power dissipation of 40W and an operating junction temperature of 150°C, it is suitable for demanding environments. The transistor is housed in a TO-126-3 package, facilitating through-hole mounting. This device is commonly utilized in power supply circuits, motor control, and general-purpose amplification within industrial and consumer electronics.
