| Market Reality | The IRF540N is the most famous TO-220 N-MOSFET in the world - the default choice of motor drivers, LED strips and hobby-class power switching, and still a production part in industrial boards. Three things make it the most-swapped MOSFET: the standard-drive specification (its low on-resistance is rated at a 10V gate, so a 5V microcontroller pin only half-drives it), a very common counterfeit problem at flea-market prices, and a suffix history (IRF540 versus the improved IRF540N die) that buyers confuse. The logic-level part of the same family, IRLZ44N, is the correct answer to most of these situations. | The IRF540N is the most famous TO-220 N-MOSFET in the world - the default choice of motor drivers, LED strips and hobby-class power switching, and still a production part in industrial boards.
