Bd679 Datasheet Site

For precise and detailed technical information, including electrical characteristics, performance curves, and application circuits, refer to the specific datasheet provided by the manufacturer.

Technically, this creates an incredibly high current gain (often denoted as $h_{FE}$). While a standard transistor might offer a gain of 100, the BD679 offers a gain of . This means a microscopic amount of current at the input can control a massive load at the output.
