IRFZ44 N N-Channel Power MOSFET 49A, 55V, 3-Pin Transistor IRF Z 44

• Small signal N-Channel MOSFET
• Continuous Drain Current (ID) is 49A at 25°C
• It is commonly used with Arduino, due to its low threshold current.
• Maximum Drain-Source Voltage (VDS) is 55V
• Pulsed Drain Current (ID-peak) is 160A

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.
