The 44 mOhm Rds(on) at 10 V gate drive sets the conduction loss: at 18 A, that is about 14 W dissipation in the channel, which the D2PAK tab must sink to a thermal plane. The 74 nC gate charge at 5 V is moderate — a 10 V gate drive with a 1 A source/sink driver switches it in roughly 74 ns, but the input capacitance of 1800 pF at 25 V drain-source means the driver sees a capacitive load that rises with drain voltage. The 2 V gate threshold ensures the device is fully enhanced with 3.3 V logic, but the Rds(on) at 4.5 V gate drive will be higher than the 44 mOhm figure — the datasheet curve (not reproduced here) typically shows a 1.5x to 2x increase below 5 V. For designs running from a 5 V rail, the logic-level threshold is a real advantage; for 3.3 V systems, verify the on-resistance at the actual gate voltage against the thermal budget.","metaTitle":"IRL540NSTRL N-Channel MOSFET, 100 V, 44 mOhm, D2PAK","metaDescription":"IRL540NSTRL N-Channel MOSFET, 100 Vdss, 36 A continuous, 44 mOhm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Cut Tape (CT)","FET Type":"N-Channel","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"2V @ 250µA","Rds On (Max) @ Id, Vgs":"44mOhm @ 18A, 10V","Supplier Device Package":"D2PAK","Gate Charge (Qg) (Max) @ Vgs":"74 nC @ 5 V","Drain to Source Voltage (Vdss)":"100 V","Input Capacitance (Ciss) (Max) @ Vds":"1800 pF @ 25 V","Current - Continuous Drain (Id) @ 25°C":"36A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8358","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4bb7d8ab131cf2037a7f806b94d927d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for IRL540NSTRL?","answer":"The IRL540N (in D2PAK) is the same die in a different packaging variant and may be a candidate, but pin compatibility and thermal performance must be verified against the original design.
