Quality Control: Learn More
The onsemi BD678AG is a PNP Darlington bipolar transistor designed for general-purpose amplification and switching applications. Featuring a 60V collector-emitter breakdown voltage and a continuous collector current capability of 4A, this component is engineered for robust performance. The BD678AG offers a high DC current gain (hFE) of at least 750 at 2A and 3V, ensuring efficient signal amplification. Its low saturation voltage of 2.8V at 40mA and 2A minimizes power loss during switching. With a maximum power dissipation of 40W and operating temperature range from -55°C to 150°C, it is suitable for demanding environments. The TO-126 package with through-hole mounting facilitates straightforward integration into printed circuit boards. This device finds application in power supply circuits, motor control, and relay driving within industrial and consumer electronics sectors.
