IRF540 MOSFET - 100V 33A N-Channel HEXFET Power MOSFET (TO-220)

Where the IRFZ44N is tuned for 12V-class systems, the IRF540 steps up to a 100V rating while still switching a hefty 33A, making it the better fit for 24V battery banks, higher-voltage motor control projects, and power-supply switching stages that would push a 55V-rated MOSFET too close to its limit. It has been in continuous production and wide use for long enough that it, too, shows up constantly in published DIY power electronics projects, making it a practical second power MOSFET to keep alongside the IRFZ44N for jobs that specifically need the extra voltage headroom.
