When an ESD event exceeds the 6.5 V minimum breakdown voltage, the steering diodes clamp the line to the supply rails at 15 V typical. For a 3.3 V HDMI receiver rated at 5 V absolute maximum, the 15 V clamp is above the device limit — the protection relies on the system's own supply clamping (TVS or bulk capacitance) to absorb the remaining energy. This is standard for rail-to-rail steering arrays; the trade-off is lower capacitance versus a standalone TVS diode. ## Four unidirectional channels in one SOT-23-6 Four unidirectional channels in a six-pin SOT-23-6 package — the pin count is tight, so the pinout is fixed: two channels share a common ground pin, and the supply rail connects to the remaining pin. Surface-mount assembly is straightforward with standard reflow profiles for SOT-23-6.","metaTitle":"TPD4E1U06DBVR ESD Protection Diode, 4-Ch Rail-to-Rail","metaDescription":"Texas Instruments TPD4E1U06DBVR 4-channel steering (rail-to-rail) ESD protection diode. 45W peak pulse, 5.5V standoff, SOT-23-6, -40 to 125°C.

The 5.5 V standoff and low capacitance (typical for rail-to-rail steering diodes) do not degrade signal integrity at the 6 Gbps data rate of HDMI 2.0, but the 15 V clamp means the downstream HDMI receiver must tolerate that voltage during an ESD event — standard practice for rail-to-rail steering arrays."},{"question":"What are the differences between TPD4E1U06DBVR and TPD4E05U06?","answer":"Both are four-channel rail-to-rail steering ESD protection arrays from Texas Instruments in SOT-23-6. The TPD4E1U06DBVR has a 5.5 V reverse standoff and 6.5 V breakdown, while the TPD4E05U06 has a 5 V standoff and 6 V breakdown. The TPD4E1U06DBVR offers a slightly higher standoff voltage, making it a better fit for 5 V logic lines; the TPD4E05U06 is optimized for 3.3 V systems with a tighter protection window. Pinout and package are identical."},{"question":"What is the peak pulse power of TPD4E1U06DBVR?","answer":"The peak pulse power rating is 45 W, measured with an 8/20 µs current waveform. This is sufficient for IEC 61000-4-2 ESD strikes at ±8 kV contact and ±15 kV air discharge, but not for high-energy surges like lightning — use a separate TVS diode for surge protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E1U06DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E1U06DBVR when reusing this data.
