Each unidirectional channel clamps incoming transients to the supply rails, keeping the protected IC's I/O pins within a safe voltage window. The 14.5 V typical clamping voltage at 3 A (8/20 µs) tells you the maximum voltage the protected IC will see during a transient. Four unidirectional channels in a single SOT-5X3 package let you protect four independent signal lines — or two differential pairs — using one component, saving board area and placement cost compared to discrete TVS diodes. The 5.5 V max reverse standoff voltage means the diode does not conduct during normal signal swings up to 5.5 V, so it does not load the line. Housed in the ultra-compact SOT-5X3 package (also listed as SOT-563 or SOT-666), this part is a surface-mount device suited for high-density PCB layouts where every square millimeter counts. No power line protection is offered — this is a signal-line ESD clamp, not a power rail suppressor. For volume commitments or dual-source planning, the base product number TPD4E1B06 covers the family; verify the exact package and reel suffix (DRLR indicates tape-and-reel) when ordering.","metaTitle":"TPD4E1B06DRLR TI ESD Protection Diode, 4-Ch Rail-to-Rail","metaDescription":"Texas Instruments TPD4E1B06DRLR steering (rail-to-rail) TVS diode array, 4 unidirectional channels, 5.5V standoff, 14.5V clamping, SOT-5X3 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":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"45W","Base Product Number":"TPD4E1B06","Operating Temperature":"-40°C~125°C(TA)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-5X3","Unidirectional Channels":"4","Voltage - Breakdown (Min)":"7V","Voltage - Clamping (Max) @ Ipp":"14.5V (Typ)","Voltage - Reverse Standoff (Typ)":"5.5V (Max)","Current - Peak Pulse (10/1000µs)":"3A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99c3528daa4f1ac96479852a3b016b72.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can TPD4E1B06DRLR be used for RS-232 protection?","answer":"Yes, the 5.5 V max reverse standoff voltage and rail-to-rail clamping architecture make it suitable for protecting RS-232 transceiver I/O lines, provided the signal swings stay within the 0 V to 5.5 V range relative to the supply rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E1B06DRLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E1B06DRLR when reusing this data.
