Each of the four unidirectional channels routes an overvoltage event to the supply rail or ground, keeping the PHY or magnetics side safe. The 100 W peak pulse power rating (8/20 µs waveform) tells you the single-pulse surge capability per channel. For a typical 10/100BASE-T Ethernet port, this is enough to survive ESD strikes (IEC 61000-4-2) and the lower-energy coupled surges from cable discharge events. It will not handle a direct lightning surge without additional series resistance or a higher-energy primary protector — the 100 W figure sets the expectation for secondary-side, board-level clamping. The small footprint keeps the trace length short between the connector and the diode — critical for maintaining low clamping inductance on fast edges.","metaTitle":"TPD4E001DRSR Steering TVS Diode Array, 4-Ch, 100 W, 6-SON","metaDescription":"Texas Instruments TPD4E001DRSR rail-to-rail steering diode array. 4 unidirectional channels, 5.5 V standoff, 100 W peak pulse, 6-SON 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":"6-WDFN Exposed Pad","Product Status":"Active","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":"6-SON (3x3)","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":"$0.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power of TPD4E001DRSR?","answer":"The TPD4E001DRSR is rated for 100 W peak pulse power per channel (8/20 µs waveform), suitable for secondary-side ESD and coupled surge protection on Ethernet ports."},{"question":"How many channels does TPD4E001DRSR have?","answer":"It has four unidirectional channels, matching the four differential pairs in a 10/100BASE-T Ethernet interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E001DRSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E001DRSR when reusing this data.
