Product details

The IRF540NL is an N-channel enhancement-mode MOSFET from Infineon's HEXFET series, built with planar stripe DMOS technology. The TO-262 (I²Pak) through-hole package handles 130 W power dissipation at the case, making it a fit for medium-voltage DC-DC converters, motor drives, battery management, and primary-side switching in 48 V telecom supplies.

Obsolete — sourcing this part in the end-of-life cycle

Buyers filling a BOM line for this part will need to source through independent distribution or surplus inventory channels.

Gate drive and switching — the 10 V drive requirement

The IRF540NL specifies a drive voltage of 10 V for achieving the rated on-resistance. A gate driver capable of sourcing and sinking that charge quickly is needed for efficient switching above 50 kHz.

Package and mounting — TO-262 through-hole

The part comes in a TO-262-3 long-lead I²Pak package, also designated TO-262AA, with through-hole mounting. The supplier device package is TO-262.

Frequently asked questions

What is the equivalent of IRF540NL?

The IRF540NL has no official successor listed. A close functional equivalent would be another 100 V N-channel MOSFET in a TO-220 or TO-262 package with similar Rds(on) and current rating, such as the IRF540N (TO-220) or IRF540NPBF (TO-220). The IRF540N shares the same die but comes in a different package — verify pin compatibility and thermal performance for your board.
