It integrates four unidirectional channels, each rated for 100W peak pulse power, and presents a typical reverse standoff voltage of 5.5V (max), which keeps the signal lines clean during normal 5V Ethernet operation while shunting transients to the supply rails. ## 100W peak pulse — enough for port-level ESD protection The 100W peak pulse power rating (8/20 µs waveform) covers the typical IEC 61000-4-2 ESD stress at the connector. For a 5V Ethernet PHY, the 5.5V max reverse standoff ensures the TVS does not clip the signal during normal line swings. The rail-to-rail steering topology routes the transient current to the positive supply or ground, which keeps the clamping voltage low and predictable — important when the PHY's internal ESD structures are weak. ## Package and footprint — 6-USON, 1.6x1.6 mm The 6-USON (1.6x1.6 mm) package is a small, leadless surface-mount package with a 0.5 mm pitch. It is a good fit for space-constrained designs like Ethernet jacks, USB ports, or HDMI connectors. The supplier device package is 6-USON (1.6x1.6), so the PCB land pattern matches the standard USON-6 footprint. Mounting is surface mount only. The storage temperature range is wider, but the operating limit governs the board-level thermal design.","metaTitle":"TPD4E001DPKR Steering (Rail to Rail) TVS, 100W, 4-Ch, 5.5V","metaDescription":"Texas Instruments TPD4E001DPKR steering (rail-to-rail) TVS diode array. 100W peak pulse power, 4 unidirectional channels, 5.5V reverse standoff, 6-USON 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-UFDFN","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-USON (1.6x1.6)","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":"$0.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is TPD4E001DPKR compatible with 5V Ethernet?","answer":"Yes.
