BD140 PNP Transistor

The BD140 is a PNP bipolar junction transistor (BJT) designed for medium-power switching and amplification applications. With a collector-emitter voltage of -80V and a maximum continuous collector current of -1.5A, it is ideal for audio amplifiers, voltage regulators, motor drivers, and general-purpose switching circuits.
