The part is explicitly listed for Ethernet port protection, where it clamps transients on the differential pairs to the supply rails rather than to ground. ## 6-USON rework — lift the part, not the pad The 1.6x1.6 mm USON package (6-USON) is a small no-lead package with a centre pad. The exposed pad under the package is the primary thermal and electrical connection — it needs a solid solder joint to the PCB ground plane. Reworking this by hand is possible with a hot-air station set to 300-320 °C, but the small body means the part heats up fast; keep the nozzle off the adjacent passives. The 0.50 mm pitch between the edge pads is tight for manual soldering — use a fine-tip iron and flux.","metaTitle":"Texas Instruments TPD4E001DPKT TVS Diode, 100W Rail-to-Rail","metaDescription":"Texas Instruments TPD4E001DPKT steering (rail-to-rail) TVS diode array, 100W peak pulse power, 4 unidirectional channels, 5.5V reverse standoff, 6-USON","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":"$1.2600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power of TPD4E001DPKT?","answer":"The TPD4E001DPKT is rated for 100 W peak pulse power. This is the maximum power the device can dissipate during an ESD or surge event, typically measured with an 8/20 µs waveform. For Ethernet port protection, this is sufficient for IEC 61000-4-2 level 4 ESD strikes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E001DPKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E001DPKT when reusing this data.
