BD139 is a popular NPN transistor ,it is 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.

BD139 is a good transistor to use in hobby and educational electronics projects for example in analog circuits, arduino projects and other microcontroller projects. This transistor can drive loads upto 1500mA therefore you can drive and control many electronic equipment’s through it. It can also be used in commercial electronics. When driving load above 200mA the transistor will dissipate heat due to which using a suitable heatsink is necessary.
