Product details
Overview
TPD4S010DQAR from Texas Instruments is a 10-pin USON-packaged four-channel TVS diode array designed for IEC 61000-4-2 Level 4 ESD protection (±8-kV contact) on high-speed differential interfaces. It delivers 0.8 pF typical I/O capacitance, 2.5 A IEC 61000-4-5 surge capability (8/20 µs), and supports >4 GHz bandwidth for HDMI 1.4 and USB 2.0 signal integrity preservation.
For engineers reviewing the TPD4S010DQAR datasheet, TPD4S010DQAR pinout, TPD4S010DQAR application, or TPD4S010DQAR equivalent, key selection criteria include low inter-pair capacitance matching, flow-through routing compatibility, absence of VCC pin (distinguishing it from TPD4S009), and USON-10 package footprint constraints for dense PCB layouts.
Technical Context
The TPD4S010DQAR implements passive bidirectional clamping using monolithic silicon TVS structures across four independent I/O channels - D1+, D1−, D2+, D2− - each referenced to GND. Its architecture omits a VCC supply pin, eliminating bias dependency and simplifying layout versus TPD4S009 variants.
During ±8-kV IEC 61000-4-2 contact discharge events, internal diodes trigger at 9 V breakdown (VBR) and clamp transient voltage to ≤12 V (VCLAMP) with 1.1 Ω dynamic resistance (RDYN), limiting stress on downstream HDMI or USB PHY receivers while maintaining <0.05 pF line-to-line capacitance mismatch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±8-kV contact / ±9-kV air per IEC 61000-4-2 Level 4 - ensures system-level robustness against human-hand ESD in consumer port interfaces. |
| Surge Rating | 2.5 A (8/20 µs) per IEC 61000-4-5 - handles induced lightning/surge transients on exposed cables without latch-up. |
| I/O Capacitance | 0.8 pF typical per pin to GND - preserves signal integrity up to 3.4 Gbps (HDMI 1.4) with minimal insertion loss. |
| Breakdown Voltage | 9 V minimum at 1 mA - sets precise clamping threshold above normal 3.3–5.5 V interface swing. |
| Dynamic Resistance | 1.1 Ω typical - minimizes clamping voltage overshoot during fast ESD pulses, reducing IC stress. |
| Leakage Current | 10 nA typical at 3.3 V IO / 5 V VCC - prevents signal degradation or false triggering in low-power standby states. |
| Operating Temperature | −40°C to +85°C - supports industrial and consumer equipment deployment without derating. |
Pinout & Package
TPD4S010DQAR uses a 10-pin USON (DQA) package measuring 2.50 mm × 1.00 mm with 0.5-mm pitch and 1.1-mm max height. The flow-through layout enables straight trace routing between connector and host IC, minimizing stubs and impedance discontinuities.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6 | D1+, D2+, D1−, D2− | Four protected high-speed differential signal terminals - symmetric placement allows flexible channel assignment for HDMI TMDS or USB D+/D− pairs. |
| 2, 5, 7, 8, 9, 10 | GND | Six dedicated ground terminals - low-inductance grounding path essential for effective ESD current shunting and noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through board layout | Enables direct routing through device without vias or layer changes - reduces signal skew and maintains controlled impedance on HDMI/USB traces. |
| Ultra-low line-to-line capacitance mismatch | ≤0.05 pF between D1+/D1− and D2+/D2− - critical for minimizing intra-pair jitter and preserving eye diagram integrity at 1.7 GHz fundamental frequency. |
| No VCC supply requirement | Operates passively without external bias - eliminates power rail dependency, simplifies BOM, and avoids startup sequencing conflicts. |
| Monolithic silicon construction | Ensures matched thermal and electrical characteristics across all four channels - guarantees consistent clamping behavior during multi-pin ESD events. |
Applications
| HDMI 1.4 Port Protection | USB 2.0 Host/Device Interface |

Use Value: Six GND pins provide low-inductance return path - critical for diverting >2.5 A surge currents without ground bounce. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4S009DGSR | 10-pin VSSOP package; includes VCC pin for Ioff functionality; 0.05 pF line-line capacitance confirmed only for DRY variant. | Required where live-signal handling during system power-off (e.g., HDMI hot-plug detection) is mandatory. | Select TPD4S009DGSR only if VCC-biased Ioff operation is needed; otherwise TPD4S010DQAR offers simpler layout and identical ESD specs. |
| TPD4E05U06DQAR | Lower 5.5 V VRWM; 0.5 pF typical capacitance; higher ±12-kV ESD rating; same USON-10 footprint. | Better suited for next-gen interfaces requiring tighter capacitance control and higher ESD margin, but may over-specify for HDMI 1.4. | Choose TPD4E05U06DQAR when upgrading to HDMI 2.0 or adding USB 3.0 support; TPD4S010DQAR remains optimal for cost-sensitive HDMI 1.4 designs. |
Compared with TPD4S009DGSR, TPD4S010DQAR removes VCC dependency for simpler integration, while versus TPD4E05U06DQAR it trades lower capacitance and higher ESD rating for proven HDMI 1.4 compatibility and broader design margin at lower cost.

FAQ
What is the primary function of the TPD4S010DQAR in a circuit?
The TPD4S010DQAR functions as a four-channel TVS diode array that provides IEC 61000-4-2 Level 4 ESD protection (±8-kV contact) for high-speed differential interfaces. It clamps transient voltages on D1+, D1−, D2+, and D2− lines to ground during ESD events, preserving signal integrity while limiting stress on downstream ICs. The TPD4S010DQAR operates passively without a VCC supply pin.
Does the TPD4S010DQAR require a power supply connection?
No, the TPD4S010DQAR does not require any power supply connection. It is a fully passive device with no VCC pin - unlike the TPD4S009 family - and relies solely on its internal TVS diode structure to respond to overvoltage transients. This eliminates power rail dependencies and simplifies layout for the TPD4S010DQAR in HDMI or USB applications.
How does the TPD4S010DQAR differ from the TPD4S009 series?
The TPD4S010DQAR differs from TPD4S009 variants by omitting the VCC supply pin, removing Ioff functionality, and using a USON-10 package instead of VSSOP or SON options. While both offer ±8-kV ESD protection and 0.8 pF I/O capacitance, the TPD4S010DQAR is optimized for flow-through routing and simplified integration where live-signal handling during power-off is not required.
What is the significance of the 0.8 pF I/O capacitance specification for the TPD4S010DQAR?
The 0.8 pF typical I/O capacitance per pin (to GND) ensures minimal loading on high-speed differential signals, enabling the TPD4S010DQAR to support HDMI 1.4 (3.4 Gbps) and USB 2.0 (480 Mbps) without significant insertion loss or eye diagram degradation. This low value directly contributes to the device's >4 GHz −3 dB bandwidth and makes it suitable for applications demanding strict signal integrity.
Can the TPD4S010DQAR be used for HDMI 2.0 or higher-speed interfaces?
The TPD4S010DQAR is characterized for HDMI 1.4 (3.4 Gbps) and USB 2.0, with a typical −3 dB bandwidth >4 GHz. While it may function in some HDMI 2.0 implementations, TI specifies TPD4E05U06DQAR - offering 0.5 pF capacitance and ±12-kV ESD - for HDMI 2.0 and beyond. For guaranteed performance at 6 Gbps+, the TPD4S010DQAR should be validated per design requirements rather than assumed compatible.
