BD140 Transistor Pinout, Equivalent
BD140 is a very famous PNP transistor used in various electronic circuits. BD140 transistor can handle current up to 1500mA or 1.5A due to this feature. It can control high-power LEDs, motors, relays, etc because it can control loads up to 1.5A. This Transistor has many other ideal features like a high collector-emitter and collector base voltage that is 80 volts. Moreover, the collector dissipation of BD140 is around 12.5 watts which is the way it is a good transistor to use in audio amplifier circuits. The minimum saturation voltage of the transistor is -0.5V.
