IRFZ44 MOSFET

• IRFZ44N N-Channel Power MOSFET
• 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.
• Alternatives for IRFZ44NIRF2807, IRFB3207, IRFB4710
• 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.
• Unlike transistors MOSFET’s are voltage controlled devices. Meaning, they can be turned on or turned off by supplying the required Gate threshold voltage (VGS). IRFZ44N is an N-channel MOSFET, so the Drain and Source pins will be left open when there is no voltage applied to the gate pin. When a gate voltage is applied these pins gets closed.
• If it is required to be switched with Arduino, then a simple drive circuit using a transistor will work to provide the required gate voltage to trigger the MOSFET to open fully. For other switching and amplifying applications, a dedicated MOFET Driver IC is required.
