The BD140 is a medium power bipolar junction PNP transistor that is mainly used for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. It is made up of silicon and comes in the TO-126 package. The PNP types are the BD136 and BD140, and the complementary NPN types are the BD135 and BD139.
The BD140 can handle current up to 1.5A, so it can drive loads up to 1.5A in electronic circuits like high power LEDs, relays, motors, etc. The BD140 also has a high collector-emitter and collector-base voltage of 80 V. Its minimum saturation voltage is -0.5V. Moreover, the collector dissipation of BD140 is around 12.5 W hence it is ideal to be used in audio amplifier circuits.
