IRF9540 P-CHANNEL MOSFET 100V 23A transistor TO-220 power MOSFET


IRF9540 is a P channel MOSFET transistor that can be used for switching and amplification purposes. The transistor is capable to drive max load of -19A with the load voltage of -100V and the max load in pulse mode can be upto -76A.


The transistor possesses high switching speed and low drain to source resistance. The high switching speed of the transistor can be useful in applications where the designer requires to switch the system or load in nano seconds so the derived circuit will face no disconnection. On the other hand the low drain to source resistance reduces power loss and makes the transistor power efficient.

When using an Arduino, we often need to control more voltage/current than can be handled directly from the Arduino pins. Most Arduino pins can handle 5VDC and 20ma of continuous current. However, other sources suggest an Arduino I/O pin can handle 40ma as an absolute maximum (without damage to the Arduino).  To control devices, such as motors, lamps, etc. that require more voltage/current than can be handled directly by the Arduino pins, we need to place a circuitry in between the Arduino and those higher I/V requirement devices such as a high voltage driver circuit. In this project, we are going to design a simple Arduino high voltage driver circuit using IRF9540 Power MOSFET.


The IRF9540N is a P-Channel Power Mosfet. The MOSFET can switch loads that consume up to 23A continuous current and operate below 100V. It also has a decent on-state resistance of 0.117O which increases the efficiency of the MOSFET since it will dissipate less heat as a loss.
