❓ Frequently Asked Questions (FAQ)
Q1: What is the maximum current and voltage rating for the IRFZ44N MOSFET?
Answer: The IRFZ44N N-Channel Power MOSFET supports a maximum Drain-Source voltage of 55V and a continuous Drain current of 49A at 25°C room temperature.
Q2: Can I trigger the IRFZ44N directly from an Arduino 5V digital pin?
Answer: The IRFZ44N has a gate threshold voltage between 2V and 4V, so a 5V Arduino signal will turn it on, but applying 10V to the gate ensures full saturation and minimal heating under heavy current loads.
Q3: Is a heatsink required when using the IRFZ44N MOSFET?
Answer: A heatsink is strongly recommended when switching continuous loads higher than 5A to prevent the TO-220 junction temperature from exceeding safe thermal limits.
