Checking for live stock

The Magnatec BD679 is a high-performance NPN darlington pair transistor designed for power switching and amplifier applications requiring substantial current gain. This robust discrete semiconductor offers a remarkable minimum DC current gain (HFE) of 750, enabling control of large loads from small input signals. Packaged in a compact 3-pin SOT-32 through-hole configuration, the BD679 is rated for a maximum continuous collector current of 4 A and a collector-emitter voltage of 80 V. It operates reliably over a broad temperature range, making it suitable for demanding industrial and consumer electronics applications.

Benefits of Using the Magnatec BD679 NPN Darlington Pair

Using the BD679 darlington pair dramatically simplifies drive circuitry by providing an exceptionally high current gain (HFE: 750). This feature enables microcontrollers or low-current logic circuits to directly switch substantial power loads directly, reducing the need for intermediate driver stages and saving valuable PCB space in power-control designs.
