Each of the 8 unidirectional channels shunts transients to the supply rails, clamping at a 9V breakdown threshold while the signal lines ride on a 5.5V reverse standoff. The 25W peak pulse rating handles the energy from IEC 61000-4-2 level 4 strikes without latching or degradation. ## HDMI signal integrity — why 8 channels and 9V breakdown matter A standard HDMI port carries four differential pairs (three data, one clock) plus the DDC and CEC lines — eight signal lines total. The TPD8S009DSMR covers one full HDMI port with a single 15-SON package, saving board area versus discrete TVS diodes. The 9V breakdown sits well above the 3.3V HDMI signal swing, so the diode capacitance stays low and the eye diagram does not close. The 5.5V reverse standoff means the part does not conduct during normal 5V DDC bus operation.","metaTitle":"TI TPD8S009DSMR HDMI Steering Diode Array, 8-Ch, 25W, 15-SON","metaDescription":"Texas Instruments TPD8S009DSMR rail-to-rail steering diode array for HDMI, 8 unidirectional channels, 25W peak pulse, 9V breakdown, -40°C to 85°C, 15-SON.","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":"HDMI","Mounting Type":"Surface Mount","Package / Case":"15-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"25W","Base Product Number":"TPD8S009","Operating Temperature":"-40°C~85°C(TA)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"15-SON","Unidirectional Channels":"8","Voltage - Breakdown (Min)":"9V","Voltage - Clamping (Max) @ Ipp":"-","Voltage - Reverse Standoff (Typ)":"5.5V (Max)","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4da7ae4e8ce1f60d6732d001c7a41a6c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPD8S009DSMR/alternatives.json"},"ai":{"faq":[{"question":"Does TPD8S009DSMR support HDMI 2.1 or 4K resolutions?","answer":"The listed application is HDMI, and the 8-channel count matches one HDMI port. The 9V breakdown and 5.5V reverse standoff are compatible with HDMI 2.0 signal levels. Whether it supports HDMI 2.1 data rates depends on the total line capacitance — the datasheet capacitance figures (not in this listing) determine the maximum TMDS clock rate. For 4K at 60 Hz (HDMI 2.0), the part is a typical fit; for 48 Gbps HDMI 2.1, verify the insertion loss budget with the full datasheet."},{"question":"Is TPD8S009DSMR RoHS compliant?","answer":"No explicit RoHS statement is in this listing; confirm the specific date-code compliance certificate with your order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD8S009DSMR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD8S009DSMR when reusing this data.
