How to Safely Long Run in a Circuit:

To get long term performance with IRFZ44N it is suggested to not use this transistor on its maximum ratings. Using any components on its maximum rating can cause stress on the component and may damage or weak it’s inside circuitry which result in weaker performance. We always suggest use any component atleat 20% below from maximum capacity or specifications. The same rule will be applied for IRFZ44N. The maximum drain current is 49 amperes therefore do not drive load of more than 39 amperes. The maximum load voltage is 55V and for safety do not drive load of more than 44V. The Gate to source voltage should be under ±20V and always store or operate the transistor in temperature above -55 centigrade and below +175 centigrade.
