The 175°C maximum junction allows derating headroom for high-current, high-ambient designs. ## Switching and drive characteristics Gate charge (Qg) is 74 nC at 5 V, and input capacitance (Ciss) is 1800 pF at 25 V drain-source. These numbers are moderate for a 100 V / 36 A device — the gate driver sees a manageable capacitive load, and switching losses at moderate frequencies (tens of kHz) are reasonable. The drive voltage range (4 V to 10 V for achieving rated Rds(on)) means a 5 V logic output can turn the device on, but the 10 V rating for minimum Rds(on) is typical for logic-level FETs; a 10 V gate supply will give the lowest conduction loss. Maximum gate-source voltage is ±16 V, so standard 12 V gate drive rails are safe. ## Obsolete — sourcing strategy New designs should not specify this part; for existing BOM lines, procurement must rely on the independent and surplus distribution channel. No official replacement part number is listed in the manufacturer's lifecycle record for this specific variant, so any substitution requires a full parametric and footprint review. ## Power dissipation and thermal design Maximum power dissipation is 3.8 W at ambient (Ta) and 140 W at case (Tc). In practice, the TO-262 package's tab is the primary heat path; a properly soldered through-hole joint to a copper plane or an external heatsink is essential for continuous operation above a few amps. The 36 A continuous drain current rating is also at Tc = 25°C; derate for real-world case temperatures.","metaTitle":"IRL540NLPBF HEXFET N-Channel MOSFET, 100V 36A TO-262","metaDescription":"Infineon IRL540NLPBF N-channel HEXFET MOSFET, 100V Vdss, 36A Id, 44mOhm Rds(on), TO-262 package, -55 to 175°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","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":"TO-262","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":"$1.5400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4bb7d8ab131cf2037a7f806b94d927d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is IRL540NLPBF obsolete?","answer":"Yes, the IRL540NLPBF is listed as Obsolete by Infineon.
