The BD442 is a PNP power transistor manufactured by On Semiconductor, designed for linear and switching industrial equipment. It offers a collector-emitter breakdown voltage of 80V, continuous collector current of 4A, and peak collector current of 7A. Power dissipation is 36W at case temperature 25°C. The transistor features a DC current gain (hFE) of 40 minimum at 500mA, 1V, and a typical gain of 140 at the same condition. Vce saturation is 0.8V maximum at 2A collector current and 0.2A base current. The device is available in a TO-126 through-hole package (also referred to as TO-225AA or SOT-32) and is supplied in tube packaging. The operating junction temperature range is -55°C to 150°C. This transistor is suitable for applications requiring medium power amplification and switching.
