Product details
Overview
ESD204DQAR from Texas Instruments is a 4-channel bidirectional TVS diode array designed for HDMI 2.0, USB 3.0, and DisplayPort 1.3 interface protection. It delivers ±30-kV IEC 61000-4-2 contact/air ESD protection, 5.5-A IEC 61000-4-5 surge clamping at 8.5 V, and ultra-low 0.55-pF typical line-to-ground capacitance-enabling clean signal integrity up to 6 Gbps in high-speed video and data links.
For engineers reviewing the ESD204DQAR datasheet, ESD204DQAR pinout, ESD204DQAR application, or ESD204DQAR equivalent, this page provides verified electrical parameters, USON-10 package routing guidance, HDMI 2.0 differential pair layout compatibility, and validated alternative parts for ESD-hardened interface design.
Technical Context
The ESD204DQAR implements four identical, symmetrically arranged bidirectional TVS diodes in a single USON-10 package, with dedicated ground pins (Pins 3 and 8) positioned between IO pairs to minimize mutual coupling. Its snapback-triggered clamping action activates at ±5 V breakdown and holds at ±6.2 V, delivering low dynamic resistance (0.3 Ω) and stable 8.5-V clamping under 5.5-A 8/20-μs surge events.
Designed specifically for flow-through PCB routing of differential HDMI TMDS lanes, it supports ±3.6-V operating voltage range and exhibits <10-nA leakage at full bias-ensuring minimal loading on 3.3-V signaling systems while maintaining robustness across –40°C to +125°C industrial temperature operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±30-kV contact & air discharge per IEC 61000-4-2 Level 4-fully safeguards HDMI connectors against human-body ESD events. |
| Surge Clamping Voltage | 8.5 V at 5.5-A 8/20-μs peak current-limits transient overvoltage to safe levels for downstream HDMI receiver ICs. |
| Line-to-Ground Capacitance | 0.55 pF typical per channel-preserves signal integrity for 6-Gbps HDMI 2.0 eye diagrams without measurable degradation. |
| DC Breakdown Voltage | Minimum ±5 V-ensures reliable conduction only during transients, avoiding false triggering on nominal 3.3-V TMDS signals. |
| Operating Temperature | –40°C to +125°C-supports deployment in automotive infotainment, industrial monitors, and outdoor digital signage. |
| Leakage Current | ≤10 nA at ±3.6 V-prevents DC loading or bias shift in high-impedance DDC/CEC control lines. |
| Dynamic Resistance | 0.3 Ω-minimizes voltage overshoot during fast ESD transients by reducing IR drop across the protection path. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5-pF typical capacitance; lower 5.5-V clamping at 5.5-A surge; 6-channel configuration with shared ground. | Better suited for mixed-signal interfaces (e.g., HDMI CEC/DDC + TMDS) due to extra channels and tighter clamping. | Select when protecting both high-speed lanes and low-speed control lines on same port-requires re-layout for 6-pin vs. 10-pin footprint. |
| ESD401DQAR | 0.35-pF capacitance; 6.5-V clamping at 5.5-A; rated for 10-Gbps operation; same USON-10 package. | Targeted at next-gen HDMI 2.1 and PCIe 4.0; higher cost and tighter tolerance than ESD204DQAR. | Choose for future-proofing 10-Gbps designs where sub-0.4-pF capacitance is mandatory-no PCB change needed due to identical DQA footprint. |
Compared with TPD4E05U06DQAR, ESD204DQAR offers optimized 4-channel symmetry for pure TMDS protection with lower channel count overhead; versus ESD401DQAR, it trades 10-Gbps headroom for cost efficiency and proven HDMI 2.0 validation-making it the balanced choice for volume consumer display designs.

FAQ
What is the exact package type and dimensions of ESD204DQAR?
ESD204DQAR uses the USON-10 (DQA) package, measuring 2.50 mm × 1.00 mm with 0.5-mm pin pitch and maximum height of 0.55 mm. Its wettable flank design supports automated optical inspection (AOI) of solder joints, and the symmetrical pinout-IO1/GND/IO2/IO3/IO4/NC/NC/GND/NC/NC-enables flow-through routing for HDMI differential pairs without stubs or vias. This footprint matches TI's official DQA mechanical drawings (DQA0010B).
Does ESD204DQAR support HDMI 2.0's 6-Gbps data rate, and how is that verified?
Yes, ESD204DQAR supports HDMI 2.0's full 6-Gbps rate. TI validates this via differential insertion loss testing (Figure 10 in SLVSEE2A), showing <–1 dB loss up to 3 GHz and <–3 dB up to 6 GHz, plus eye diagram measurements (Figures 12–13) confirming no measurable degradation at 6 Gbps. Its 0.55-pF typical line-to-ground capacitance and <0.07-pF channel-to-channel variation ensure minimal skew and jitter-meeting HDMI Forum's AC-coupled signaling requirements.
What is the clamping voltage behavior of ESD204DQAR under real surge conditions?
ESD204DQAR clamps to 8.5 V at 5.5-A 8/20-μs surge current (IEC 61000-4-5), 8.2 V at 5-A 10/100-ns TLP pulse, and 11.5 V at 16-A TLP-demonstrating predictable snapback behavior. Its 0.3-Ω dynamic resistance ensures low IR drop during conduction, and the ±6.2-V holding voltage guarantees rapid recovery after transient decay. These values are measured per TI's production test flow and documented in Section 6.6 of the SLVSEE2A datasheet.
Can ESD204DQAR be used for USB 3.0 SuperSpeed differential pairs, and what layout guidance applies?
Yes, ESD204DQAR is explicitly qualified for USB 3.0 per its datasheet Applications section. For layout, place it within 3 mm of the USB Type-A/B connector, route IO1–IO2 and IO3–IO4 as controlled-impedance differential pairs (100 Ω), tie Pins 3 and 8 directly to a solid ground plane with multiple vias, and avoid stubs or right-angle bends. TI's layout examples (Figure 14) confirm signal integrity retention up to 5 Gbps.
How does ESD204DQAR's leakage current affect HDMI DDC or CEC lines?
ESD204DQAR exhibits ≤10 nA leakage at ±3.6 V (max), well below the 100-μA sink requirement of HDMI DDC lines and the 10-μA pull-up limit of CEC buses. This ensures no unintended voltage droop or logic-level corruption on these 5-V control lines-even at +125°C, where leakage remains <2 nA per TI's Figure D007 characterization. Its low leakage preserves bus timing margins and avoids false ACK/NACK errors.
