Description
The IRFZ44N N-Channel Power MOSFET is a voltage-controlled semiconductor used to switch and control current in electronic circuits. Its low on-state resistance helps reduce conduction losses when the gate receives an appropriate drive voltage.
The IRFZ44N is commonly used in DC motor controllers, battery-powered systems, switching power supplies, LED controllers, and other power-control applications. Its TO-220 package supports through-hole PCB mounting and heatsink installation, making it useful for electronics prototyping and repair.
Although the MOSFET may begin conducting at a relatively low gate voltage, the gate-threshold voltage does not indicate that the device is fully switched on. For high-current applications, use a suitable gate driver and verify the on-resistance at the intended gate voltage.
