Quality Control: Learn More
The onsemi BD442 is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. This component features a collector-emitter breakdown voltage (Vce) of 80V and a maximum continuous collector current (Ic) of 4A. With a maximum power dissipation of 36W, it is suitable for moderate power handling. The BD442 offers a minimum DC current gain (hFE) of 40 at 500mA and 1V, with a transition frequency of 3MHz. It is provided in a TO-126 package for through-hole mounting. Typical applications for this device include power supply circuits, audio amplifiers, and general switching in industrial and consumer electronics.
