MOSFET IRFZ44N 49A 55V TO-220


MOSFET, or metal-oxide-semiconductor field-effect-transistor, is a four-terminal semiconductor device used for switching and amplifying signals. MOSFETs are voltage-controlled devices. This means in order to use them, you need first to overcome a threshold voltage. Beginners often stick to MOSFETS for this particular feature. Because compared to BJT (Bipolar Junction Transistor), which is current-controlled, you can directly drive a MOSFET using a microcontroller pin's voltage.

To demonstrate, to drive a BJT, you need to calculate first the value of the base resistor. Whereas in a MOSFET, just apply enough voltage to the gate and the switch triggers. If you wish to use a MOSFET with an Arduino, it is always a standard procedure to include at least a 220 ohms resistor to limit the current. It is because MOSFETs are highly capacitive. It can draw high instantaneous current when you turn it on, which can damage your board.
