Its two unidirectional channels map directly to the transmit and receive pairs of a single 10/100 Ethernet port, with a reverse standoff voltage of 5.5V (max) that sits above a 3.3V supply rail yet below the typical PHY absolute maximum rating. The 11V minimum breakdown gives headroom for the clamping action without loading the signal during normal operation. ## Package and rework — 6-SON with exposed pad Housed in a 6-WDFN with exposed pad (also listed as 6-SON, 3x3 mm body), this part is surface-mount only. The pad pitch is fine enough that solder paste volume matters more than reflow profile. For a BOM line protecting Ethernet ports on a multi-year production run, this part does not introduce obsolescence risk today.","metaTitle":"TPD2E001DRST-NM Steering TVS Diode, 2-Ch, 5.5V, 6-SON","metaDescription":"Texas Instruments TPD2E001DRST-NM steering (rail-to-rail) TVS diode array, 2 unidirectional channels, 5.5V reverse standoff, 6-SON (3x3) 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":"-","Base Product Number":"TPD2E001","Operating Temperature":"-40°C~85°C(TA)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"6-SON (3x3)","Unidirectional Channels":"2","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":"$0.9365","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/835388424c1b3d9a57c0dfc0e5a4de23.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPD2E001DRST-NM/alternatives.json"},"ai":{"faq":[{"question":"Is TPD2E001DRST-NM suitable for 10/100 Ethernet protection?","answer":"Yes. The two unidirectional channels cover the TX and RX differential pairs of a single 10/100 Ethernet port. The steering (rail-to-rail) topology clamps transients to the supply rails, which is the standard approach for PHY-side protection on 3.3V or 5V biased lines. The 5.5V reverse standoff keeps the diode out of conduction during normal signal swings."},{"question":"What is the difference between TPD2E001DRST-NM and TPD2E001DRLR?","answer":"The two parts share the same TPD2E001 die and electrical specs — both are 2-channel steering TVS arrays. The difference is the package: TPD2E001DRST-NM comes in a 6-SON (3x3) with exposed pad, while TPD2E001DRLR is in a smaller SOT-5X3 (1.6x1.6 mm) package. The SON variant offers better thermal dissipation through the pad, which matters if the application sees repetitive surge events; the SOT variant saves board area for space-constrained designs. Pinout differs between the two packages, so a direct PCB swap is not possible without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD2E001DRST-NM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD2E001DRST-NM when reusing this data.
