It is housed in a surface-mount D2PAK (TO-263-3) package, making it a fit for high-current power switching on a PCB — motor drives, battery management, DC-DC conversion, and low-voltage power distribution where board space is tight and conduction loss matters. The 6 mOhm maximum on-resistance at 10 V gate drive with 71 A drain current governs I²R loss in the steady-state conduction path. ## Gate drive and switching — 4.5 V threshold, 140 nC gate charge Drive voltage range is 4.5 V to 10 V for achieving the rated on-resistance. Maximum gate threshold is 1 V at 250 µA. ## Temperature range and environment — -55°C to 175°C junction Junction temperature range spans -55°C to 175°C. ## Package and mounting — D2PAK (TO-263-3) Surface-mount D2PAK, three leads plus the tab. The tab is the drain — common to the centre lead in the TO-263 footprint. ## Lifecycle and compliance The IRL3803STRLPBF is listed as Active in production. ROHS3 compliant, so it meets the current exemption framework for EU and global BOMs.","metaTitle":"IRL3803STRLPBF HEXFET N-Ch MOSFET, 30V 140A D2PAK","metaDescription":"IRL3803STRLPBF N-channel 30V 140A HEXFET MOSFET in D2PAK. 6 mOhm Rds(on) at 10V, 175°C Tj, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"HEXFET®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"HEXFET®","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±16V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1V @ 250µA","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"6mOhm @ 71A, 10V","Power Dissipation (Max)":"3.8W (Ta), 200W (Tc)","Supplier Device Package":"D2PAK","Gate Charge (Qg) (Max) @ Vgs":"140 nC @ 4.5 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"5000 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"140A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.54000","currency":"USD"},{"qty":10,"price":"$2.28500","currency":"USD"},{"qty":100,"price":"$1.83700","currency":"USD"},{"qty":800,"price":"$1.50928","currency":"USD"},{"qty":1600,"price":"$1.25773","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f7f01698709319f83977071ba2e1125d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is IRL3803STRLPBF RoHS compliant?","answer":"Yes, the IRL3803STRLPBF is ROHS3 compliant, meeting the current RoHS exemption rules."},{"question":"What is the difference between IRL3803STRLPBF and IRL3803PBF?","answer":"The IRL3803STRLPBF and IRL3803PBF are electrically identical — same 30 V / 140 A / 6 mOhm ratings and same D2PAK package. The difference is the packaging format: the STRLPBF suffix indicates Tape & Reel (TR) for automated assembly, while the PBF suffix typically indicates tube or bulk packaging.

If a pin-compatible alternative is needed for dual-sourcing, a part in the same 30 V, 140 A, D2PAK class with similar gate charge and Rds(on) would be the closest cross-shop candidate — verify the specific gate-drive and thermal requirements against the datasheet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRL3803STRLPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRL3803STRLPBF when reusing this data.
