IRFZ44N N-Channel Power MOSFET


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.
