Product details
Overview
TPD8S009DSMR from Texas Instruments is an 8-channel TVS diode array designed for system-level ESD protection of high-speed differential interfaces, featuring ±8kV IEC 61000-4-2 contact discharge rating, 0.8pF typical I/O capacitance, 2.5A IEC 61000-4-5 surge capability, –40°C to +85°C operating range, and support for HDMI 1.4 and DisplayPort 1.1 signal integrity up to 3.4Gbps.
For engineers reviewing the TPD8S009DSMR datasheet, TPD8S009DSMR pinout, TPD8S009DSMR application, or TPD8S009DSMR equivalent, this device delivers low-capacitance, flow-through routing ESD protection optimized for HDMI/DisplayPort connector-level placement with verified clamping performance and Ioff functionality for live-signal hot-plug scenarios.
Technical Context
The TPD8S009DSMR implements a passive diode-clamp architecture with matched differential pair paths, enabling symmetrical transient suppression without signal skew. Its internal structure includes bidirectional clamping diodes between each I/O pin and GND/VCC, with a blocking diode at VCC to enable Ioff operation when VCC = 0V.
Each of the eight channels operates independently with identical electrical characteristics: 5.5V reverse standoff voltage (VRWM), 9V breakdown voltage (VBR), 1.1Ω dynamic resistance (RDYN), and 10nA typical leakage at 3.3V IO bias - ensuring consistent protection across all TMDS lanes while preserving signal fidelity above 4GHz bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8kV contact / ±9kV air per IEC 61000-4-2 Level 4 - ensures compliance with end-equipment immunity requirements for consumer and industrial displays. |
| Surge Rating | 2.5A peak pulse current (8/20µs) - handles transient energy from lightning-induced surges on external cables without degradation. |
| I/O Capacitance | 0.8pF typical per channel - minimizes signal distortion and insertion loss for HDMI 1.4 (1.7GHz fundamental) and DisplayPort 1.1 links. |
| Bandwidth | >4GHz –3dB bandwidth - supports data rates up to 3.4Gbps with negligible eye closure in TMDS applications. |
| Leakage Current | 10nA typical at 3.3V IO / 5V VCC - prevents DC loading on source drivers and maintains signal integrity during idle states. |
| Operating Temp | –40°C to +85°C - validated for use in laptops, set-top boxes, and video surveillance equipment under real-world thermal conditions. |
| VRWM | 5.5V - safely isolates protected lines from system supply rails while allowing full HDMI signal swing (0–3.6V). |
Pinout & Package
The TPD8S009DSMR is housed in a 15-pin SON (DSM) package measuring 2.50mm × 6.50mm, optimized for straight-through routing adjacent to HDMI and DisplayPort connectors. Its layout aligns precisely with standard high-speed interface pinouts to minimize trace stubs and preserve impedance continuity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9, 10, 12 | D0+ / D0– / D1+ / D1– / D2+ / D2– / D3+ / D3– | Eight independent ESD clamp ports - each pair protects one differential TMDS lane; symmetric layout enables matched trace routing. |
| 2, 5, 8, 11, 14 | GND | Five dedicated ground terminals - provide low-inductance return paths for clamped ESD/surge current and reduce ground bounce. |
| 13, 15 | VCC | Optional supply pin with internal blocking diode - enables Ioff mode for hot-plug operation when VCC = 0V; no effect on ESD performance if left unconnected. |
| 14 | N.C. | No internal connection - electrically isolated pad; must be left floating or tied to GND per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Ioff Functionality | Enables safe live-signal handling on D+/D– pins when VCC = 0V - critical for HDMI hot-plug detection during system power-down. |
| Flow-Through Routing | Pin arrangement matches HDMI/DisplayPort connector layouts - eliminates need for vias or layer transitions, reducing signal path discontinuities. |
| Differential Pair Matching | Matched internal capacitance and clamping thresholds across D+/D– pairs - preserves common-mode rejection and minimizes skew & jitter. |
| Low Dynamic Resistance | 1.1Ω RDYN - ensures rapid clamping response and low clamping voltage (<12V at 2.5A), protecting downstream receivers from overstress. |
| Industrial Temp Range | Validated operation from –40°C to +85°C - supports deployment in uncontrolled environments like digital signage and outdoor surveillance systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD8S010DSMR | Same 15-pin SON package but with integrated 5V VCC regulator and enhanced 12kV ESD rating; higher VRWM (6.5V); 1.0pF capacitance. | Better suited for newer HDMI 2.0 designs requiring tighter clamping voltage and regulated supply rail; less optimal for legacy 3.3V-only systems. | Select TPD8S010DSMR only if system requires active VCC regulation and higher ESD margin; otherwise TPD8S009DSMR offers lower capacitance and simpler implementation. |
| SZP8S009T1G | ON Semiconductor equivalent in 15-pin WSON; identical pinout and 0.8pF capacitance; ±8kV ESD; slightly higher leakage (20nA typ) and lower surge rating (2.0A). | Drop-in replacement for cost-sensitive designs where minor leakage increase and reduced surge margin are acceptable. | Choose SZP8S009T1G for dual-sourcing flexibility in production; verify layout compatibility and validate surge performance in final system testing. |
Compared with TPD8S009DSMR, TPD8S010DSMR adds regulated VCC functionality at the cost of higher capacitance and complexity, while SZP8S009T1G provides second-source availability with trade-offs in leakage and surge robustness - making TPD8S009DSMR the optimal balance of performance, simplicity, and proven interoperability with HDMI/DP connectors.

FAQ
What is the primary function of the TPD8S009DSMR in HDMI and DisplayPort designs?
The TPD8S009DSMR serves as an 8-channel ESD protection device placed at the connector interface to safeguard high-speed differential TMDS and main link signals from electrostatic discharge events. It uses low-capacitance TVS diodes to clamp transients to ground or VCC without degrading signal integrity, and its pinout matches HDMI and DisplayPort connectors to simplify PCB layout. The TPD8S009DSMR is not a signal conditioner or repeater - it operates passively and only activates during overvoltage events.
Can the TPD8S009DSMR be used without connecting the VCC pin?
Yes, the TPD8S009DSMR functions correctly with VCC unconnected or tied to ground, thanks to its Ioff feature enabled by an internal blocking diode. This allows the device to protect live signals on D+/D– pins even when the host system is powered off - a key requirement for HDMI hot-plug detection. Leaving VCC unconnected does not affect ESD performance, as clamping occurs directly to GND through the diode network.
What is the maximum data rate supported by the TPD8S009DSMR?
The TPD8S009DSMR supports differential data rates up to 3.4Gbps, corresponding to HDMI 1.4 and DisplayPort 1.1 specifications. This is enabled by its 0.8pF typical I/O capacitance and >4GHz –3dB bandwidth, which limit insertion loss to less than 0.5dB at 1.7GHz (the fundamental frequency of a 3.4Gbps NRZ signal). Eye diagram testing confirms minimal distortion at 2.5Gbps, validating margin for full-rate operation.
How does the TPD8S009DSMR differ from general-purpose TVS diodes?
Unlike discrete TVS diodes, the TPD8S009DSMR integrates eight matched, low-capacitance clamps in a single 15-pin SON package with pin assignments aligned to HDMI/DisplayPort differential pairs. Its 0.8pF capacitance, differential pair matching, and flow-through routing eliminate crosstalk and skew issues common with discrete solutions. The TPD8S009DSMR also includes Ioff functionality and is characterized for system-level IEC 61000-4-2/4-5 compliance - features absent in generic TVS arrays.
Is the TPD8S009DSMR compatible with HDMI 2.0 or DisplayPort 1.2+ interfaces?
The TPD8S009DSMR is specified and validated for HDMI 1.4 (3.4Gbps) and DisplayPort 1.1 (2.7Gbps), with measured bandwidth >4GHz providing margin for these standards. While it may function at higher data rates, TI does not characterize or guarantee performance beyond those specifications - especially for HDMI 2.0 (6Gbps) or DP 1.2+ (5.4Gbps+), where tighter capacitance control and lower clamping voltage become critical. For those interfaces, TI recommends TPD8S010DSMR or similar next-generation variants.
