onsemi BD678G is a PNP Darlington bipolar transistor designed for robust power applications. This through-hole component, housed in a TO-126 package, offers a 60V collector-emitter breakdown voltage and a continuous collector current capability of 4A. The device exhibits a high DC current gain (hFE) of 750 minimum at 1.5A and 3V, indicative of its suitability for amplification and switching tasks requiring significant current gain. With a maximum power dissipation of 40W and a saturation voltage of 2.5V at 30mA base current and 1.5A collector current, the BD678G is engineered for efficient operation. Its operating temperature range of -55°C to 150°C (TJ) ensures reliability across diverse environmental conditions. This component finds application in power supply circuits, motor control, and general-purpose amplification within industrial and consumer electronics.
