Product details
Overview
ESD224DQAR from Texas Instruments is a 4-channel bidirectional TVS diode array designed for HDMI 2.0 interface protection, featuring ±12-kV contact / ±15-kV air IEC 61000-4-2 ESD rating, 0.5-pF typical IO-to-GND capacitance, 8-V system-side clamping at 16-A TLP, and industrial –40°C to +125°C operation. It protects TMDS differential pairs (D0+/–, D1+/–, D2+/–, CLK+/–) in high-speed video interfaces.
For engineers reviewing the ESD224DQAR datasheet, ESD224DQAR pinout, ESD224DQAR application, or ESD224DQAR equivalent, this device serves as a low-capacitance, high-bandwidth ESD suppressor optimized for 6-Gbps HDMI 2.0 signal integrity, system-side clamping validation, and compact USON-10 layout integration near connectors.
Technical Context
The ESD224DQAR employs on-chip differentially matched series elements to maintain signal fidelity while enhancing downstream clamping performance. Its symmetrical pinout-pairing connector-side (IOx_C) and system-side (IOx_S) terminals with internal GND shorts-enables direct placement between HDMI connector and SoC without trace splitting.
It operates passively: triggering above ±5.5-V DC breakdown (VBRF/VBRR), clamping transients to ≤14 V (TLP, 16 A), and sustaining ≤0.1-nA leakage at ±3.6 V. The ultra-low 0.5-pF line capacitance and <0.3-dB DC insertion loss preserve HDMI 2.0 eye diagrams up to 3 GHz fundamental frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±12-kV contact / ±15-kV air discharge - meets Level 4 immunity for consumer/industrial HDMI ports |
| Clamping Voltage (TLP) | 8 V at 16-A (system side) - limits voltage seen by downstream HDMI driver during ESD strike |
| IO-to-GND Capacitance | 0.5 pF (typical) - enables 6-Gbps data rates without signal degradation or jitter increase |
| DC Breakdown Voltage | ±5.5 V minimum - ensures protection activation before HDMI signal rails (±3.6 V) are exceeded |
| Leakage Current | 0.1 nA (typical) at ±3.6 V - prevents DC loading of high-impedance TMDS receivers |
| Operating Temperature | –40°C to +125°C - supports deployment in set-top boxes, monitors, and automotive infotainment |
| Surge Rating (IEC 61000-4-5) | 2 A (8/20 µs) - provides secondary protection against lightning-induced surges on cable-connected interfaces |
Pinout & Package
ESD224DQAR is housed in a 2.50 mm × 1.00 mm USON-10 (DQA) package with 0.5-mm pitch, no leads, and exposed thermal pad (not electrically connected). Pin 1 index is marked via laser etch in quadrant Q1; pins 3 and 8 are internally shorted GND terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IO1_C) | Connector-side I/O channel 1 | Connects to HDMI TMDS D0+ or D1+; paired with pin 10 (IO1_S) for differential path |
| 2 (IO2_C) | Connector-side I/O channel 2 | Connects to HDMI TMDS D0– or D1–; paired with pin 9 (IO2_S) for differential path |
| 3 (GND) | Ground reference | Primary GND terminal; internally shorted to pin 8; must be low-inductance PCB connection |
| 4 (IO3_C) | Connector-side I/O channel 3 | Connects to HDMI TMDS D2+ or CLK+; paired with pin 7 (IO3_S) |
| 5 (IO4_C) | Connector-side I/O channel 4 | Connects to HDMI TMDS D2– or CLK–; paired with pin 6 (IO4_S) |
| 6 (IO4_S) | System-side I/O channel 4 | Routes protected signal to HDMI SoC; requires direct trace to IC pin, no stubs |
| 7 (IO3_S) | System-side I/O channel 3 | Routes protected signal to HDMI SoC; maintains symmetry with pin 4 for differential balance |
| 8 (GND) | Ground reference | Secondary GND terminal; internally shorted to pin 3; improves ground return path for all channels |
| 9 (IO2_S) | System-side I/O channel 2 | Routes protected signal to HDMI SoC; mirrors pin 2 for matched length routing |
| 10 (IO1_S) | System-side I/O channel 1 | Routes protected signal to HDMI SoC; completes differential pair with pin 1 |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06 | 4-channel, 0.5-pF, ±5.5-V VBR, but rated only to 3-Gbps; lacks HDMI 2.0 validation | Targeted at USB 2.0, LVDS, or lower-speed HDMI 1.4 interfaces | Select when cost sensitivity outweighs 6-Gbps margin and HDMI 2.0 certification is not required |
| ESD401DQAR | 4-channel, 0.35-pF, ±12-kV ESD, but 10.5-V clamping at 16-A TLP - 31% higher than ESD224DQAR | Used in PCIe Gen3 or MIPI D-PHY where lower capacitance offsets higher clamping | Select only if system-level testing confirms 10.5-V clamping is acceptable for HDMI receiver absolute max ratings |
Compared with TPD4E05U06 and ESD401DQAR, ESD224DQAR uniquely delivers HDMI 2.0–validated 6-Gbps operation with the lowest clamping voltage (8 V) among USON-10 4-channel protectors, making it optimal for next-generation display interfaces where signal integrity and robustness are co-constrained.

FAQ
What is the maximum data rate supported by ESD224DQAR?
ESD224DQAR supports data rates up to 6 Gbps, as validated in HDMI 2.0 compliance testing. Its 0.5-pF typical IO-to-GND capacitance and <0.3-dB DC insertion loss ensure minimal signal degradation at 3 GHz fundamental frequency, preserving eye diagram integrity in real-world layouts. This capability is confirmed in TI's SLVSEB4A datasheet Figure 9 and Application Report SLLA307.
Does ESD224DQAR require external bias or power supply?
No, ESD224DQAR is a passive TVS diode array and requires no external power or bias circuitry. It operates solely on transient voltage thresholds: triggering above ±5.5 V (VBRF/VBRR) and clamping ESD energy to GND. Per Section 10 of the SLVSEB4A datasheet, users must only ensure signal voltages remain within the recommended –3.6 V to +3.6 V operating range.
How does the pinout of ESD224DQAR support differential HDMI signaling?
ESD224DQAR uses a symmetrical pinout with dedicated IOx_C (pins 1,2,4,5) and IOx_S (pins 6,7,9,10) terminals, plus dual GND pins (3 and 8) placed between differential pairs. This allows direct routing of each TMDS lane (e.g., D0+ → pin 1 → pin 10 → SoC) without trace splitting, maintaining impedance control and minimizing skew - a key requirement for HDMI 2.0 timing budgets.
Can ESD224DQAR be used for USB 3.0 protection?
Yes, ESD224DQAR is explicitly listed in its datasheet Applications section for USB 3.0 interfaces. Its 0.5-pF capacitance, ±12-kV/±15-kV ESD rating, and 6-Gbps capability align with SuperSpeed USB requirements. However, USB 3.0 implementations must verify layout adherence to TI's guidance on avoiding through-routing (Section 9.1) to maintain clamping performance.
What is the thermal resistance profile of ESD224DQAR in its USON-10 package?
ESD224DQAR in the DQA package has RθJB = 77.6°C/W (junction-to-board) and RθJA = 173.4°C/W (junction-to-ambient), per Section 6.5 of SLVSEB4A. These values assume standard JEDEC 2-layer board construction; actual thermal performance improves with enhanced copper pour under the exposed pad area, though the pad is not electrically connected.
