The BD136 is a medium power PNP transistor. It can be used to control heavy loads since it has a high collector current value of 1.5A. Another peculiar fact about this transistor is that it comes in plastic package, while most medium power transistor are available only in metal can package. This reduces the cost of the Transistor and also since the package is not conductive it will not be affected by other noise in the circuit. Due to this feature this transistor is widely used in amplifier applications.

So if you are looking for a medium power PNP transistor in Plastic package then this Transistor might be the right choice for you.
