With a reverse standoff voltage of 3.6V (max) and a clamping voltage of 8V at 1A peak pulse current (8/20µs waveform), it protects downstream ICs on USB 2.0, USB 3.0, HDMI, and other high-speed differential interfaces. ## Clamping voltage and signal integrity The 8V clamping voltage at 1A is the key parameter for design margin: it defines the maximum voltage the protected IC's I/O pins will see during an ESD event. For a USB 3.0 PHY with a 3.6V absolute maximum rating, the 8V clamp leaves 4.4V of headroom — adequate for IEC 61000-4-2 level 4 (±8 kV contact, ±15 kV air) when the diode array is placed close to the connector. The low capacitance typical of steering diodes (not specified here, but inherent to the topology) preserves signal edge rates on 5 Gbps USB 3.0 lanes. ## Package and footprint for high-speed layout Housed in a 3-pin SOT-23-3 variant (SOT-3), this surface-mount device occupies minimal board area and places the protection diodes close to the connector pins — a critical practice for minimizing loop inductance and achieving the rated clamping performance. The small footprint suits space-constrained designs in mobile devices, dongles, and compact I/O modules.","metaTitle":"TPD2EUSB30ADRTR Steering Rail-to-Rail ESD Protection","metaDescription":"Texas Instruments TPD2EUSB30ADRTR steering (rail-to-rail) ESD protection diode array.","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":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"3-SMD, SOT-23-3 Variant","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"45W","Base Product Number":"TPD2EUSB30","Operating Temperature":"-40°C~85°C(TA)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-3","Unidirectional Channels":"2","Voltage - Breakdown (Min)":"4.5V","Voltage - Clamping (Max) @ Ipp":"8V","Voltage - Reverse Standoff (Typ)":"3.6V (Max)","Current - Peak Pulse (10/1000µs)":"1A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/36a5b23a75f16b689eac7a1314efff17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPD2EUSB30ADRTR/alternatives.json"},"ai":{"faq":[{"question":"Is TPD2EUSB30ADRTR compatible with USB 3.0?","answer":"Yes.
