The 4.7 mOhm max on-resistance at 20 A with 8 V gate drive sets the conduction-loss floor in a synchronous buck or load switch — at 20 A the dissipation is under 2 W in the channel alone. The 7.1 nC gate charge at 4.5 V drive keeps switching losses manageable for 300–500 kHz converters without oversizing the gate driver. ## 8-VSONP package and thermal budget The 3 W power dissipation at 25°C ambient (Ta) is the board-level limit — the actual headroom depends on the copper area and airflow. For a 12 V input, 1.2 V output buck at 20 A, the junction rise stays inside the -55°C to 150°C rating if the thermal pad is connected to a 1 oz inner-layer plane. ## Active production, no obsolescence pressure No NRND or last-time-buy notice is in effect. The BOM line is stable for current and new designs — no need to qualify a substitute or stockpile for an EOL window.","metaTitle":"CSD16342Q5A NexFET N-Channel MOSFET, 25V 100A","metaDescription":"Texas Instruments CSD16342Q5A NexFET N-Channel MOSFET, 25V drain-source, 100A continuous drain, 4.7 mOhm Rds(on) max at 20A, 8V.","metaKeywords":null},"attributes":{"series":"NexFET™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"NexFET™","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"+10V, -8V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Surface Mount","Package / Case":"8-PowerTDFN","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1.1V @ 250µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"4.7mOhm @ 20A, 8V","Power Dissipation (Max)":"3W (Ta)","Supplier Device Package":"8-VSONP (5x6)","Gate Charge (Qg) (Max) @ Vgs":"7.1 nC @ 4.5 V","Drain to Source Voltage (Vdss)":"25 V","Input Capacitance (Ciss) (Max) @ Vds":"1350 pF @ 12.5 V","Drive Voltage (Max Rds On, Min Rds On)":"2.5V, 8V","Current - Continuous Drain (Id) @ 25°C":"100A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.16000","currency":"USD"},{"qty":10,"price":"$1.03800","currency":"USD"},{"qty":100,"price":"$0.80900","currency":"USD"},{"qty":500,"price":"$0.66832","currency":"USD"},{"qty":1000,"price":"$0.52762","currency":"USD"},{"qty":2500,"price":"$0.49245","currency":"USD"},{"qty":5000,"price":"$0.46783","currency":"USD"},{"qty":12500,"price":"$0.45024","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1350c3627c74d3bb702ca44174ffa165.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CSD16342Q5A obsolete?","answer":"No — the product status is Active."},{"question":"What is the Rds(on) of CSD16342Q5A?","answer":"Maximum on-resistance is 4.7 mOhm at 20 A drain current with 8 V gate-source drive."},{"question":"What is the gate charge of CSD16342Q5A?","answer":"Maximum total gate charge is 7.1 nC at 4.5 V gate-source voltage."},{"question":"Is CSD16342Q5A RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CSD16342Q5A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CSD16342Q5A when reusing this data.
