The DirectFET package uses a can-style top-side cooling that pulls heat up through the board, so the thermal path depends on the via pattern under the die, not a traditional tab. ## Gate charge at 4.5 V — switching-loss reality check Total gate charge is 17 nC at 4.5 V, which is the figure a designer uses to size the gate driver. For a 500 kHz switching regulator, the gate-drive current needed is Qg × f = 17 nC × 500 kHz = 8.5 mA average, plus the peak current to charge the gate capacitance quickly — a standard 1 A driver handles that easily. The threshold voltage is 2.4 V max at 25 µA, so a 5 V logic-level gate drive fully enhances the channel; a 3.3 V GPIO may leave it in the linear region, increasing conduction loss.","metaTitle":"IRF6721STRPBF N-Channel MOSFET, 30V, 7.3 mOhm Rds(on)","metaDescription":"IRF6721STRPBF N-Channel MOSFET, 30 V drain-source, 7.3 mOhm Rds(on) at 14 A, 17 nC gate charge.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Vgs":"±20 V","series":"DirectFET™","power_w":"2.2","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Surface Mount","capacitance_uf":"0.0014","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"30.0","Vgs(Th) (Max) @ Id":"2.4 V @ 25µA","switching_current_a":"14.0","Rds On (Max) @ Id, Vgs":"7.3mOhm @ 14 A, 10 V","Operating Temperature High":"-40°C to 150°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"17 nC @ 4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.44","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06fcc378f14149456eca486a2ab597f7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the gate charge of IRF6721STRPBF?","answer":"Total gate charge is 17 nC at 4.5 V gate-source voltage."},{"question":"What is IRF6721STRPBF's Vgs rating?","answer":"The maximum gate-source voltage is ±20 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRF6721STRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRF6721STRPBF when reusing this data.
