IRFZ44N MOSFET N-channel

The IRFZ44N is a N-channel MOSFET with a high drain current of 49A and low Rds value of 17.5 mΩ. It also has a low threshold voltage of 4V at which the MOSFET will start conducting. Hence it is commonly used with microcontrollers to drive with 5V. However, a driver circuit is needed if the MOSFET has to be switched in completely. The IRFZ44N is known for its high drain current and fast switching speed. Adding to that it also has a low Rds value which will help in increasing the efficiency of switching circuits. The MOSFET will start turning on with a small gate voltage of 4V, but the drain current will be maximum only when a gate voltage of 10V is applied. If the mosfet has to be driven directly from a microcontroller like Arduino then try the logic level version IRLZ44N mosfet.
