Each of the four unidirectional channels clamps transients above a 6.1V breakdown minimum, with a 3V reverse standoff for normal signal levels. The array is rated for 35W peak pulse power, enough for IEC 61000-4-2 level 4 contact ESD strikes on general-purpose I/O lines. The 3V reverse standoff means the part clamps signals above 3V, so it is a natural fit for 3.3V logic families — think UART, SPI, or GPIO lines on a microcontroller. The 6.1V minimum breakdown gives a 3.1V window above the rail before the Zener conducts, which keeps leakage low during normal operation. No power-line protection here — the part is designed for signal lines only, so keep it off the power bus. The base product number TPD4E002 covers the family; the DRL2 suffix specifies the SOT-553 tape-and-reel variant. RoHS compliance is standard for this TI series, so it passes the usual environmental restrictions for commercial and industrial builds.","metaTitle":"TPD4E002DRL2 Zener ESD Protection Array, 4-Ch, 35W, SOT-553","metaDescription":"Texas Instruments TPD4E002DRL2 Zener ESD protection array, 4 unidirectional channels, 35W peak pulse, 3V reverse standoff, SOT-553.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Texas Instruments","Type":"Zener","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SOT-553","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"35W","Base Product Number":"TPD4E002","Operating Temperature":"-40°C~125°C(TA)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-5","Unidirectional Channels":"4","Voltage - Breakdown (Min)":"6.1V","Voltage - Clamping (Max) @ Ipp":"-","Voltage - Reverse Standoff (Typ)":"3V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1594","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/001ff3dd14649eedb6e312020c625924.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TPD4E002DRL2 support 5V or USB applications?","answer":"The reverse standoff voltage is 3V, so the part is not designed for 5V logic or USB VBUS lines. It is intended for 3.3V and lower signal rails. For 5V USB data lines, look at a TVS diode with a 5V or higher standoff rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E002DRL2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E002DRL2 when reusing this data.
