Any available units are from distributor or broker inventory that was produced before the last-time-buy window closed. ## 100V / 36A / 44mOhm — the replacement spec window The gate threshold is 2 V max at 250 µA, and the device is specified with a drive voltage range of 4 V to 10 V for achieving the rated Rds(on). Total gate charge is 74 nC at 5 V, and input capacitance is 1800 pF at 25 V. These numbers define the switching and conduction performance that a replacement must meet or exceed. ## TO-262 through-hole — mechanical fit constraint The IRL540NL is packaged in a TO-262-3 with long leads, also known as I²Pak or TO-262AA. This is a through-hole mounting package, not surface-mount. Any pin-compatible alternative must share this same three-lead TO-262 footprint and lead form to drop into an existing PCB layout without board rework.","metaTitle":"IRL540NL HEXFET N-Channel MOSFET, 100V 36A TO-262","metaDescription":"Obsolete IRL540NL N-channel HEXFET MOSFET. 100V Vdss, 36A Id, 44mOhm Rds(on).
