20pcs Bd139 Bd140 ( 10pcs Bd139 + 10pcs Bd140 ) Amplifier Power Transistor

BD139 and BD 140 are popular NPN and PNP transistors used in wide variety of electronic circuits, due to its high collector current and low cost it is an ideal transistor to be used in educational electronic projects and also in commercial electronics.

It can drive loads upto 1.5A which is a good feature due to which you can drive many high current components such as high power LEDs, high current relays, motors etc.

The collector-emitter and collector-base voltage is also very high therefore it can easily survive in an electronic circuit that is operated under 80 volts.

The collector dissipation is 12.5W due to which it is also ideal to use it in audio amplifier circuits. The saturation voltage of the transistor is just 0.5V.
