Maximum on-resistance is 1.4 mOhm at 40 A with 10 V gate drive. At 40 A, dissipation in the channel is manageable with good PCB copper area but not without it. ## Gate drive and switching considerations The drive voltage range is specified for both 4.5 V and 10 V. At 4.5 V the Rds(on) is higher than the 1.4 mOhm at 10 V, but the gate charge is lower — 39 nC at 4.5 V. It is RoHS3 compliant.","metaTitle":"CSD17556Q5B NexFET N-Channel MOSFET, 30V, 1.4mOhm, 8-VSON","metaDescription":"CSD17556Q5B N-channel NexFET MOSFET: 30V Vdss, 1.4mOhm Rds(on) at 40A, 10V. 34A (Ta) / 100A (Tc), -55 to 150°C.","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)":"±20V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Surface Mount","Package / Case":"8-PowerTDFN","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1.65V @ 250µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"1.4mOhm @ 40A, 10V","Power Dissipation (Max)":"3.1W (Ta), 191W (Tc)","Supplier Device Package":"8-VSON-CLIP (5x6)","Gate Charge (Qg) (Max) @ Vgs":"39 nC @ 4.5 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"7020 pF @ 15 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"34A (Ta), 100A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5","priceTiers":[{"qty":1,"price":"$2.50000","currency":"USD"},{"qty":10,"price":"$2.24300","currency":"USD"},{"qty":100,"price":"$1.80260","currency":"USD"},{"qty":500,"price":"$1.48102","currency":"USD"},{"qty":1000,"price":"$1.22714","currency":"USD"},{"qty":2500,"price":"$1.14250","currency":"USD"},{"qty":5000,"price":"$1.10019","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/47ebc85bdbd04a1d7ae9fe322d684351.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CSD17556Q5B/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for CSD17556Q5B?","answer":"No direct pin-compatible replacement is listed in the official records.
