BD140 Transistor  Description:

BD140 Transistor is a famous PNP type transistor.

It is used in many electronics circuits, this transistor can handle current upto 1.5A or 1500mA.

Due to which it can be used to drive loads upto 1.5A in electronic circuits, for example high power LEDs, relays, motors and more, with these features it has lots of other features like its high collector emitter and collector base voltage that is 80 volts.

make it an ideal transistor to use in  circuits using 80 volts DC or below 80 volts.

The collector dissipation of this transistor is around 12.5 watt due to which it’s a good transistor to use in audio amplifier circuits.

The minimum base voltage or saturation voltage of the transistor is -0.5V.

Where We Can Use it & How to Use:

Also used in industrial electronics.

The load this transistor can drive is 1.5A.

When using this transistor for load more than 200mA.

Use a suitable heatsink with it.

Applications:
