At 100 kHz, the average gate-drive current is 14.5 mA — well within a standard driver's capability — but the peak current needed to charge the 11340 pF input capacitance in a few tens of nanoseconds calls for a driver with at least 2 A peak output. The ±20 V Vgs max gives headroom for a 12 V or 15 V gate drive rail without clamping. ## Temperature grade and what it buys you For industrial designs that see high ambient or frequent thermal cycling, that qualification is a reliability shortcut.","metaTitle":"BUK751R8-40E127 N-Channel MOSFET, 1.8 mOhm, 40 V, TO-220","metaDescription":"NXP BUK751R8-40E127 automotive AEC-Q101 N-channel TrenchMOS MOSFET, 1.8 mOhm Rds(on) at 10 V, 120 A continuous, TO-220AB.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101, TrenchMOS™","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Series":"Automotive, AEC-Q101, TrenchMOS™","Package":"Bulk","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Through Hole","Package / Case":"TO-220-3","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 1mA","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"1.8mOhm @ 25A, 10V","Power Dissipation (Max)":"349W (Tc)","Supplier Device Package":"TO-220AB","Gate Charge (Qg) (Max) @ Vgs":"145 nC @ 10 V","Drain to Source Voltage (Vdss)":"40 V","Input Capacitance (Ciss) (Max) @ Vds":"11340 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"120A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.88","stockQuantity":0,"priceTiers":[{"qty":340,"price":"$0.88000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/16a8935a77c4f79b6d82043c2d88e274.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the BUK751R8-40E127 RoHS compliant?","answer":"The part is listed with a Bulk package and is from NXP's TrenchMOS automotive series, which is typically RoHS-compliant.
