Product details
Overview
TPD4S009DBVR from Texas Instruments is a 4-channel TVS diode array for IEC 61000-4-2 Level 4 ESD protection of high-speed differential interfaces, featuring ±8-kV contact discharge rating, 0.8-pF typical I/O-to-GND capacitance, 10-nA typical leakage at 3.3 V, and support for >4 GHz bandwidth signals - deployed in USB 2.0, HDMI 1.4, and LVDS port protection.
For engineers reviewing the TPD4S009DBVR datasheet, TPD4S009DBVR pinout, TPD4S009DBVR application, or TPD4S009DBVR equivalent, this page delivers verified package mapping (SOT-23/DBV), confirmed pin functions (D1+/D1−/D2+/D2−/GND/VCC), real-world ESD clamping behavior (±8-kV contact, 2.5 A surge), and validated alternatives for HDMI/USB interface hardening.
Technical Context
The TPD4S009DBVR implements a monolithic 4-channel TVS architecture with bidirectional clamping diodes per channel, where each I/O pair (D1+, D1− and D2+, D2−) shares matched 0.8-pF capacitance to ground and <0.05-pF line-to-line capacitance mismatch - enabling minimal signal skew in HDMI TMDS and USB D+/D− lanes. Its internal VCC pin connects to a blocking diode that enables the Ioff feature, allowing live-signal tolerance during system power-off states.
It operates passively without supply bias but leverages the optional VCC pin (5 V max) to stabilize internal node potentials at startup; clamping triggers when I/O voltage exceeds ±9 V breakdown (VBR) or drops below −0.6 V forward conduction, diverting ESD current (<10 ns response) to GND while maintaining <1.1 Ω dynamic resistance (RDYN) under 1-A surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8-kV contact discharge - meets Level 4 system-level ESD immunity for USB/HDMI connectors exposed to user handling. |
| I/O Capacitance | 0.8 pF (typical, per pin to GND) - preserves signal integrity up to 3.4 Gbps data rates (e.g., HDMI 1.4 full-bandwidth operation). |
| Breakdown Voltage (VBR) | 9 V (min, at 1 mA) - ensures clamping activates before damage to downstream 3.3-V or 5-V interface ICs. |
| Dynamic Resistance (RDYN) | 1.1 Ω (typical, at 1 A) - limits clamping voltage (VCLAMP) to safe levels during transient events, reducing stress on protected ICs. |
| Leakage Current | 10 nA (typical, at 3.3 V IO, 5 V VCC) - avoids DC loading on high-impedance differential receivers (e.g., HDMI sink PHY). |
| Operating Temperature | −40°C to +85°C - supports industrial-grade deployment in set-top boxes, laptops, and EPOS terminals. |
| Surge Rating (IEC 61000-4-5) | 2.5 A (8/20 µs waveform) - provides secondary protection against longer-duration transients beyond ESD. |
Pinout & Package
SOT-23 (DBV) package: 6-pin, 2.90 mm × 1.60 mm body, 1.1 mm max height, JEDEC MO-178 compliant; optimized for compact routing near USB/HDMI connectors.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D1+ | Positive terminal of first differential channel - routes directly to USB D+ or HDMI TMDS D1+ trace. |
| 2 | GND | Common ground reference for all clamps - must connect to low-inductance system GND plane near connector. |
| 3 | D2+ | Positive terminal of second differential channel - used for USB D− or HDMI TMDS D2+ (depending on layout symmetry). |
| 4 | D2− | Negative terminal of second differential channel - paired with Pin 3 for matched impedance routing. |
| 5 | VCC | Optional bias pin for Ioff functionality - enables live-signal tolerance when pulled to 0 V during system power-down (e.g., HDMI hot-plug scenarios). |
| 6 | D1− | Negative terminal of first differential channel - paired with Pin 1 for differential signal integrity and skew control. |
Key Features
| Feature | Design Value |
|---|---|
| Ioff capability via VCC pin | Enables safe connection of live differential signals (e.g., HDMI D+/D−) while system VCC is off - critical for hot-plug compliance. |
| Ultra-low inter-pair capacitance mismatch | 0.05 pF line-to-line capacitance matching - minimizes intra-pair skew and preserves eye diagram integrity at 1.7 GHz HDMI clock rates. |
| Flow-through PCB routing | Pin 1–6 layout allows straight trace routing through device - reduces stubs, reflections, and layout redesign effort in existing designs. |
| Industrial temperature range | Validated operation from −40°C to +85°C - suitable for uncontrolled ambient environments in consumer and commercial electronics. |
| Low dynamic resistance | 1.1 Ω RDYN ensures clamping voltage stays low (<5 V) during 2.5-A surges - protects sensitive 3.3-V interface receivers. |
Applications
| USB 2.0 Port Protection | HDMI 1.4 Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4S010DQAR | 10-pin USON package, no VCC pin, identical 0.8-pF capacitance and ±8-kV ESD rating. | Lacks Ioff functionality; requires external pull-down if live-signal tolerance needed; better suited for space-constrained layouts with flow-through routing. | Select when VCC bias is unnecessary and smaller footprint (2.5 mm × 1.0 mm) is prioritized over hot-plug robustness. |
| TPD4E05U06DQAR | Lower capacitance (0.5 pF), higher ESD rating (±12-kV contact), lower clamping voltage (VCLAMP ≈ 7 V), same 10-pin USON footprint. | Better suited for next-gen HDMI 2.0/USB 3.0 interfaces requiring tighter signal integrity; not pin-compatible with TPD4S009DBVR. | Choose for future-proofing high-speed designs where sub-0.6-pF loading and enhanced surge margin justify re-layout. |
Compared with TPD4S009DBVR, TPD4S010DQAR removes the VCC pin and shrinks the package but sacrifices Ioff capability, while TPD4E05U06DQAR improves capacitance and clamping performance at the cost of non-drop-in replacement - making TPD4S009DBVR optimal for legacy USB/HDMI systems needing live-signal tolerance in SOT-23 form factor.

FAQ
What is the primary function of the VCC pin on the TPD4S009DBVR?
The VCC pin on the TPD4S009DBVR enables the Ioff feature: when pulled to 0 V, it allows live differential signals (e.g., HDMI D+/D−) to be present on the I/O pins even while the host system is powered down. This supports hot-plug compliance and prevents false triggering during power sequencing. The TPD4S009DBVR remains fully functional without VCC bias, as it is a passive TVS device.
Does the TPD4S009DBVR require external power to operate?
No, the TPD4S009DBVR is a passive TVS diode array and requires no external power to provide ESD protection. Its clamping action is purely voltage-triggered (at ±9 V breakdown). The VCC pin is optional and used only to enable the Ioff feature - connecting or omitting VCC has no effect on basic ESD performance or clamping behavior of the TPD4S009DBVR.
Can the TPD4S009DBVR be used for HDMI 2.0 or USB 3.0 interfaces?
The TPD4S009DBVR is validated for HDMI 1.4 (3.4 Gbps, 1.7 GHz) and USB 2.0 (480 Mbps). While its 0.8-pF capacitance and >4 GHz bandwidth suggest theoretical compatibility, HDMI 2.0 (6 Gbps) and USB 3.0 (5 Gbps) demand tighter capacitance matching and lower clamping voltages - TI recommends TPD4E05U06DQAR for those applications. The TPD4S009DBVR is not characterized for those speeds.
What is the maximum recommended trace length between the TPD4S009DBVR and the protected connector?
Texas Instruments recommends placing the TPD4S009DBVR within 5 mm of the USB or HDMI connector to minimize inductance in the ESD current path. Longer traces increase impedance, raising clamping voltage and risking coupling into adjacent nets. Layout guidelines also specify rounded corners and avoidance of vias between the TPD4S009DBVR and connector to preserve signal integrity and ESD effectiveness.
How does the TPD4S009DBVR compare to discrete diode-based ESD solutions?
The TPD4S009DBVR integrates four matched TVS channels in a single SOT-23 package, ensuring consistent capacitance (<0.05 pF mismatch), low leakage (10 nA), and precise VBR (9 V min) - unlike discrete diodes which suffer from parameter spread and layout-induced imbalance. This monolithic design eliminates manual matching, reduces PCB area by >60%, and guarantees differential pair skew control essential for HDMI/USB timing budgets.
