It clamps incoming spikes by steering the surge current to the supply or ground rail, keeping the protected line within the IC's voltage tolerance. ## 11V breakdown — the actual clamp threshold The minimum breakdown voltage is 11V, meaning the device starts conducting at that level to shunt energy away from the protected line. The reverse standoff voltage is 5.5V max, so the part sits transparently on 3.3V or 5V signal lines without loading them. Peak pulse power handling is 100W, enough for the short-duration ESD strikes typical on Ethernet cable interfaces. ## Active and production-stable This is a standard Texas Instruments catalog part, available through independent distribution for BOM qualification or production replenishment.","metaTitle":"Texas Instruments TPD4E001DRLRG4 Steering (Rail to Rail) TVS","metaDescription":"Texas Instruments TPD4E001DRLRG4 steering (rail-to-rail) TVS diode array, 4 unidirectional channels, 11V breakdown, 100W peak pulse, SOT-5X3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Texas Instruments","Type":"Steering (Rail to Rail)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Ethernet","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","lifecycle_stage":"eol_hot","Power - Peak Pulse":"100W","Base Product Number":"TPD4E001","Operating Temperature":"-40°C~85°C(TA)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-5X3","Unidirectional Channels":"4","Voltage - Breakdown (Min)":"11V","Voltage - Clamping (Max) @ Ipp":"-","Voltage - Reverse Standoff (Typ)":"5.5V (Max)","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is TPD4E001DRLRG4 RoHS compliant?","answer":"The TPD4E001DRLRG4 is a lead-free, RoHS-compliant device as standard for Texas Instruments catalog parts in this package family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E001DRLRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E001DRLRG4 when reusing this data.
