IRF9540

The IRF9540 is a P channel mosfet able to support 23A and 100V from Source to Drain. The intensity able to pass through the mosfet is depending of the Gate-to-Source voltage. When Gate-to-Source is 0V (Gate connected to Source) the mosfet is open, the controlled circuit is disconnected from source. When the Gate is connected to GND, the mosfet is closing and the max intensity is defined by the voltage difference between Gate and Source. This is about 1A for 4.5V, 3A for 5V, 6A for 5.5V
