The 5.5V max reverse standoff voltage means this part will not conduct leakage current on signal lines operating up to 5.5V — suitable for 3.3V and 5V logic families, including automotive CAN, LIN, and 10/100 Ethernet PHY interfaces. The 11V minimum breakdown voltage provides a predictable trigger point, and the 16V typical clamping voltage limits the voltage seen by the protected IC during an ESD event. With 5.5A peak pulse current capability (8/20 µs), it can absorb the energy from IEC 61000-4-2 level 4 ESD strikes without damage. ## Four channels, one package — board area efficiency Four unidirectional channels in a single SOT-23-6 package saves board space compared to using four discrete TVS diodes. Each channel can protect one signal line (e.g., four data lines of an Ethernet PHY or four GPIOs). The rail-to-rail architecture steers the transient to the supply or ground rail, which means the protected IC sees only the clamping voltage above the rail. Power line protection is built in (yes), so the device can also clamp transients on the supply rail itself.","metaTitle":"TPD4E001QDBVRQ1 Steering (Rail to Rail) TVS, AEC-Q100","metaDescription":"Texas Instruments TPD4E001QDBVRQ1 is an automotive AEC-Q100 qualified steering (rail-to-rail) TVS 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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive, Ethernet","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"100W","Base Product Number":"TPD4E001","Operating Temperature":"-40°C~125°C(TA)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-23-6","Unidirectional Channels":"4","Voltage - Breakdown (Min)":"11V","Voltage - Clamping (Max) @ Ipp":"16V (Typ)","Voltage - Reverse Standoff (Typ)":"5.5V (Max)","Current - Peak Pulse (10/1000µs)":"5.5A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1afb0e961a8d8a8ae4584a238353716.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TPD4E001QDBVRQ1 have AEC-Q100 qualification?","answer":"Yes, the TPD4E001QDBVRQ1 is part of the Automotive, AEC-Q100 series, meaning it is qualified for automotive-grade applications including under-hood and chassis-domain electronics."},{"question":"Can TPD4E001QDBVRQ1 be used for 10/100 Ethernet protection?","answer":"Yes, the device is explicitly listed for Automotive and Ethernet applications.
