Pinout

The BD135 is a NPN bipolar junction transistor (BJT) commonly used for general-purpose amplification and switching applications. It has a total of 3 pins with the following functions:
1. Pin 1 (Emitter): This pin is used for the emitter terminal, where current flows out of the transistor. It is typically connected to the ground or negative voltage in a circuit.
2. Pin 2 (Base): This is the base terminal, which controls the transistor's operation. A small current applied to this pin allows a larger current to flow from collector to emitter, thus facilitating amplification.
3. Pin 3 (Collector): The collector pin receives the current coming into the transistor from the load. This is where the output current is taken.
The BD135 is suited for applications requiring moderate current handling and is widely used in amplifier circuits, switch applications, and as a driver for other components.
