Product details
Overview
TPD4S009DBVRG4 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 capacitance, 10-nA typical leakage current at 3.3 V, and support for >4 GHz bandwidth - deployed in USB 2.0, HDMI 1.4, and LVDS port protection.
For engineers reviewing the TPD4S009DBVRG4 datasheet, TPD4S009DBVRG4 pinout, TPD4S009DBVRG4 application, or TPD4S009DBVRG4 equivalent, this device delivers low-capacitance, matched-pair transient suppression with Ioff capability for live-signal hot-plug scenarios in industrial-grade (-40°C to 85°C) embedded video and connectivity systems.
Technical Context
The TPD4S009DBVRG4 implements a monolithic silicon TVS structure with four independent bidirectional clamping diodes per channel, each referenced to GND and optionally biased via VCC to enable Ioff functionality. Its internal architecture includes a central clamp network with blocking diodes at VCC to isolate supply during power-off states.
It operates passively without external bias but leverages the VCC pin (Pin 5) to stabilize internal node potentials during system startup - critical for HDMI hot-plug compliance. Triggering occurs at ≥9 V breakdown (VBR) and clamps transients to <12 V (VCLAMP) under 2.5-A IEC 61000-4-5 surge conditions, with dynamic resistance (RDYN) of 1.1 Ω ensuring minimal voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±8-kV contact / ±9-kV air per IEC 61000-4-2 Level 4 - ensures robust system-level ESD immunity at connector interface |
| I/O Capacitance | 0.8 pF typical per pin - preserves signal integrity up to 3.4 Gbps (HDMI 1.4) with <0.05-pF inter-pair mismatch |
| Breakdown Voltage (VBR) | 9 V minimum at 1 mA - defines safe operating margin above 5.5-V VRWM and enables reliable clamping onset |
| Leakage Current | 10 nA typical at 3.3-V IO / 5-V VCC - minimizes standby power loss and avoids signal distortion on high-impedance lines |
| Surge Rating | 2.5 A (8/20 µs), 25 W peak - handles IEC 61000-4-5 line-to-ground surges without degradation |
| Operating Temperature | –40°C to +85°C - supports industrial deployment in set-top boxes, DTVs, and laptop docking stations |
| Dynamic Resistance (RDYN) | 1.1 Ω - limits clamping voltage rise during fast transients, protecting downstream PHY receivers |
Pinout & Package
SOT-23 (DBV) package: 2.90 mm × 1.60 mm body, 1.1-mm max height, 6-pin surface-mount outline with gull-wing leads. Optimized for compact routing near USB/HDMI connectors.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D1+ | Positive input of first differential pair - clamped bidirectionally to GND and VCC for ESD path control |
| 2 | GND | Primary ground reference for all clamping diodes - must be low-inductance connection to system GND plane |
| 3 | D2+ | Positive input of second differential pair - matched capacitance and layout symmetry preserve TMDS signal skew |
| 4 | D2− | Negative input of second differential pair - paired with D2+ for balanced high-speed data protection |
| 5 | VCC | Optional bias supply pin - enables Ioff mode; allows live-signal operation during system power-down (e.g., HDMI hot-plug) |
| 6 | D1− | Negative input of first differential pair - maintains 0.05-pF inter-pair capacitance match with D1+ for <100-fs skew |
Key Features
| Feature | Design Value |
|---|---|
| Ioff Functionality | VCC-biased internal blocking diode enables safe live-signal handling on D+/D− when system supply is off - essential for HDMI CEC and HPD compliance |
| Differential Pair Matching | 0.05-pF line-to-line capacitance tolerance between D1+/D1− and D2+/D2− - minimizes intra-pair skew and jitter in 1.7-GHz TMDS links |
| Flow-Through Layout | Straight-through pin arrangement (D1+, D1−, GND, D2+, D2−, VCC) enables minimal trace detour - reduces PCB layer count and insertion loss |
| Industrial Temp Range | –40°C to +85°C operation - validated across temperature for stable clamping voltage and leakage in consumer electronics enclosures |
| Low Dynamic Resistance | 1.1 Ω RDYN - ensures clamping voltage stays below 12 V under 2.5-A surge, protecting 3.3-V logic interfaces |
Applications
| HDMI 1.4 Port Protection | USB 2.0 Connector 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 | No VCC pin; USON-10 package; identical 0.8-pF capacitance and ±8-kV ESD rating | Lacks Ioff functionality - unsuitable for hot-plug interfaces requiring live-signal operation during power-off | Select when board layout prioritizes flow-through routing over Ioff, and VCC bias is unavailable |
| TPD4E05U06DQAR | Lower 5.5-V VRWM; 0.5-pF capacitance; P2P compatible with TPD4S010DQAR but not TPD4S009DBVRG4 | Better suited for 3.3-V-only interfaces; higher ESD robustness (±12-kV contact) but reduced voltage margin | Choose for cost-sensitive 3.3-V designs needing enhanced ESD margin, accepting non-drop-in replacement effort |
Compared with TPD4S010DQAR and TPD4E05U06DQAR, the TPD4S009DBVRG4 uniquely combines SOT-23 compactness, Ioff-enabled hot-plug readiness, and industrial temperature support - making it optimal for space-constrained HDMI/USB ports where system power sequencing is variable.

FAQ
What is the primary function of the VCC pin on the TPD4S009DBVRG4?
The VCC pin on the TPD4S009DBVRG4 enables the Ioff feature: it biases internal clamping nodes to allow live-signal operation on D1+/D1− and D2+/D2− even when system power is off. This is critical for HDMI hot-plug detection and USB enumeration during suspend. The TPD4S009DBVRG4 remains fully functional without VCC connection, but Ioff requires it to be tied to the system supply rail.
Does the TPD4S009DBVRG4 meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, the TPD4S009DBVRG4 is rated for ±8-kV contact discharge and ±9-kV air-gap discharge per IEC 61000-4-2 Level 4. This rating is validated across its full operating temperature range (–40°C to +85°C) and applies to all four I/O channels (D1+, D1−, D2+, D2−), with clamping voltage maintained below 12 V under test conditions.
What is the typical I/O capacitance of the TPD4S009DBVRG4, and why does it matter?
The TPD4S009DBVRG4 has a typical I/O capacitance of 0.8 pF per pin to GND. This low value is essential for preserving signal integrity on high-speed differential interfaces like HDMI 1.4 (3.4 Gbps) and USB 2.0 (480 Mbps), minimizing insertion loss and maintaining >4 GHz –3 dB bandwidth - directly enabling clean eye diagrams and reliable bit-error-rate performance.
Can the TPD4S009DBVRG4 replace the TPD4S010DQAR in an existing design?
No - the TPD4S009DBVRG4 uses a 6-pin SOT-23 (DBV) package with VCC pin, while the TPD4S010DQAR uses a 10-pin USON (DQA) package without VCC. They are not pin-compatible or footprint-compatible. Migration requires PCB redesign, though both offer identical 0.8-pF capacitance and ±8-kV ESD rating for differential pair protection.
What is the maximum surge current the TPD4S009DBVRG4 can handle per IEC 61000-4-5?
The TPD4S009DBVRG4 is rated for 2.5 A peak pulse current under the 8/20 µs waveform defined in IEC 61000-4-5. It sustains this surge with a clamping voltage below 12 V and dissipates up to 25 W peak power, ensuring downstream PHY ICs remain within safe operating voltage limits during lightning-induced or inductive-switching transients.
