BD135 BD-135 BD 135 NPN Transistor 45V 1.5A NPN Power Transistor TO-126 Bipolar Transistor IC Medium Power Silicon NPN Triode Transistor
BD135 is one of the transistors of the popular BD series in which you will also find other widely used transistor such as BD131, BD137, BD139 and their PNP compliments. BD135 is also a widely used transistor due to its variety of useful features. The collector current of upto 1.5A and max collector dissipation 12.5 Watt makes this transistor a very useful device to use in wide variety of switching and amplification purposes.
When used as a switch it will be able to drive loads upto 1.5A that means we can control a variety of components with this transistor in our electronic circuits. For example you can drive high power LEDs, relays, high power transistors and many other components in an electronic circuit. As mentioned above it can also be used as an amplifier for audio and other types of signal amplification.
Moreover it is also an ideal transistor to be used at the output of microcontrollers and other ICs which has low current at their outputs.
