The logic-level threshold (2V max at 250µA) means a 5V logic output can turn it on hard enough for moderate loads, but for the full 36A rating you want the full 10V drive to keep the channel resistance at its minimum. Gate charge is 74nC at 5V, so a gate driver with 1A peak current will switch it in the tens of nanoseconds; the 1800pF input capacitance at 25V drain-source is moderate for a 100V device. ## Where it fits — switching and load-switch roles The 100V rating and 36A continuous current suit this part for 48V bus converters, battery-management disconnect switches, motor-drive half-bridges up to a few hundred watts, and DC-DC stages where the input rail is 24V to 72V. The logic-level gate threshold also makes it usable as a high-side load switch driven directly from a 5V microcontroller GPIO, as long as the load current stays within the Rds(on) at that gate voltage.","metaTitle":"IRL540NSPBF N-Channel MOSFET, 100V, 36A, 44mΩ D2PAK","metaDescription":"IRL540NSPBF HEXFET N-channel MOSFET: 100V Vdss, 36A Id, 44mΩ Rds(on) at 10V, logic-level gate, D2PAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"HEXFET®","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±16V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"2V @ 250µA","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"44mOhm @ 18A, 10V","Power Dissipation (Max)":"3.8W (Ta), 140W (Tc)","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","Drive Voltage (Max Rds On, Min Rds On)":"4V, 10V","Current - Continuous Drain (Id) @ 25°C":"36A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4bb7d8ab131cf2037a7f806b94d927d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of IRL540NSPBF?","answer":"The maximum on-resistance is 44mΩ at 18A drain current with a 10V gate drive.
