Introducción

Electronics is an intriguing world where tiny components wield immense power! Today, we will explore one of these powerhouses – the IRF540N MOSFET.

Imagine this: an energy-saving transistor designed by International Rectifier that can efficiently handle high currents while switching in nanoseconds. This is the IRF540N MOSFET, an N-channel power MOSFET (Metal Oxide Semiconductor Field Effect Transistor). Let’s move on to discussing the three terminals that comprise this MOSFET. Imagine three friends, each playing an essential part in this powerful device:
