Product details
Overview
TPD4S009DCKR 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, and support for >4-GHz bandwidth signals. It protects USB 2.0, HDMI 1.4, and LVDS signal paths in space-constrained consumer and industrial end equipment.
For engineers reviewing the TPD4S009DCKR datasheet, TPD4S009DCKR pinout, TPD4S009DCKR application, or TPD4S009DCKR equivalent, this device delivers low-capacitance, matched-pair transient suppression with optional VCC biasing for live-signal handling during system power-off - critical for HDMI hot-plug compliance and signal integrity preservation.
Technical Context
The TPD4S009DCKR implements monolithic silicon TVS clamping across four independent channels, each with bidirectional breakdown at 9 V (min) and dynamic resistance of 1.1 Ω. Its architecture includes internal central clamp circuitry biased via an optional VCC pin, enabling the Ioff feature that maintains safe operation when D+/D− lines are live while VCC = 0 V.
Designed for passive operation without supply dependency, it triggers on overvoltage events exceeding ±8 kV (IEC 61000-4-2) or 2.5 A surge (IEC 61000-4-5), diverting transients to GND with clamping voltage held below safe thresholds for downstream ICs. Capacitance matching between differential pairs (0.05 pF line-line) minimizes intra-pair skew in HDMI and USB 2.0 applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±8-kV contact discharge (IEC 61000-4-2 Level 4) - ensures robust system-level ESD immunity at connector interface |
| I/O Capacitance | 0.8 pF (typical) - enables signal integrity retention up to 3.4 Gbps data rates (e.g., HDMI 1.4) |
| Breakdown Voltage | 9 V (min) - defines minimum overvoltage threshold before clamping activation |
| Dynamic Resistance | 1.1 Ω - limits clamping voltage rise under 2.5-A surge (8/20 µs), protecting sensitive receivers |
| Leakage Current | 10 nA (typical at 3.3 V IO, 5 V VCC) - prevents DC loading of high-impedance signal lines |
| Operating Temperature | –40°C to +85°C - supports industrial and consumer ambient conditions without derating |
| VCC Pin Function | Optional supply bias for internal node stabilization and Ioff mode - allows live-signal protection during system power-down |
Pinout & Package
TPD4S009DCKR uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body, 0.65-mm pitch, 1.1-mm max height, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1+ | ESD port (Channel 1 positive) | Clamps high-speed differential signal line (e.g., HDMI TMDS D1+ or USB D+) |
| D1− | ESD port (Channel 1 negative) | Paired with D1+; matched capacitance preserves differential signal integrity |
| GND | Ground reference | Low-inductance return path for ESD/surge current; must connect directly to solid ground plane |
| D2+ | ESD port (Channel 2 positive) | Second differential pair clamp (e.g., HDMI TMDS D2+ or USB D−) |
| D2− | ESD port (Channel 2 negative) | Paired with D2+; identical electrical characteristics ensure inter-pair timing alignment |
| VCC | Optional bias supply | Enables Ioff functionality; connects to system 3.3 V or 5 V rail to stabilize internal nodes during startup |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low I/O capacitance | 0.8 pF typical per channel - preserves 3.4-Gbps HDMI 1.4 eye diagram integrity with <0.5-dB insertion loss at 1.7 GHz |
| Differential pair capacitance matching | 0.05 pF line-to-line mismatch - reduces intra-pair skew to <1 ps, critical for HDMI pixel clock alignment |
| Ioff capability | VCC-biased internal clamp allows live-signal protection when system is unpowered - required for HDMI hot-plug detection compliance |
| Flow-through routing layout | Linear pin arrangement (D1+, D1−, GND, D2+, D2−, VCC) enables straight PCB trace routing - minimizes impedance discontinuities and crosstalk |
| Industrial temperature range | –40°C to +85°C operation - validated across full range with no parameter drift beyond spec limits |

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 separate biasing for live-signal scenarios like HDMI hot-plug | Select when board layout prioritizes flow-through routing without VCC connection and Ioff is not required |
| TPD4E05U06DQAR | Lower 0.5-pF capacitance; higher 12-V breakdown; P2P compatible with TPD4S010DQAR but not TPD4S009DCKR | Better suited for 5-Gbps USB 3.0 or DisplayPort 1.2 where lower capacitance outweighs need for Ioff | Choose for next-gen interfaces requiring <0.6-pF loading; verify pin compatibility and VCC absence in schematic |
Compared with TPD4S010DQAR and TPD4E05U06DQAR, TPD4S009DCKR uniquely combines SC70-6 footprint efficiency, Ioff-enabled live-signal protection, and HDMI-optimized capacitance matching - making it the preferred choice for compact, hot-plug–compliant HDMI 1.4 designs.

FAQ
What is the primary function of the VCC pin on the TPD4S009DCKR?
The VCC pin on the TPD4S009DCKR provides optional biasing for internal clamp circuitry, enabling the Ioff feature. When connected to the system supply (3.3 V or 5 V), it stabilizes internal node voltages during power-up sequences. Critically, it allows the TPD4S009DCKR to safely protect live D+/D− signals even when the host system is powered off - a requirement for HDMI hot-plug detection compliance. The TPD4S009DCKR remains fully functional without VCC connection, as it operates passively.
Does the TPD4S009DCKR support HDMI 1.4 data rates?
Yes, the TPD4S009DCKR supports HDMI 1.4 data rates up to 3.4 Gbps. Its 0.8-pF typical I/O capacitance and >4-GHz 3-dB bandwidth ensure minimal signal degradation, while its 0.05-pF differential pair capacitance matching reduces intra-pair skew to <1 ps - both verified in TI's HDMI eye diagram testing. The device is explicitly referenced in the datasheet for HDMI 1.4 applications and maintains >80% eye opening at 1.7 GHz fundamental frequency.
How does the TPD4S009DCKR differ from the TPD4S010DQAR in terms of ESD protection capability?
The TPD4S009DCKR and TPD4S010DQAR share identical core ESD specifications: both provide ±8-kV contact discharge (IEC 61000-4-2 Level 4), 0.8-pF I/O capacitance, and 2.5-A surge current (IEC 61000-4-5). Their key difference lies in architecture - the TPD4S009DCKR includes a VCC pin enabling Ioff mode for live-signal protection, whereas the TPD4S010DQAR omits VCC and cannot support hot-plug scenarios without external biasing. Both meet the same ESD performance standards.
What is the recommended PCB layout practice for the TPD4S009DCKR?
TI recommends placing the TPD4S009DCKR as close as possible to the protected connector - ideally within 5 mm - to minimize trace inductance and prevent EMI coupling during ESD events. Use straight, impedance-controlled traces between connector and device with rounded corners (≥0.5-mm radius) to avoid field concentration. Connect the GND pin directly to a solid ground plane using multiple vias, and route the VCC pin (if used) with low-inductance path to the system supply. Avoid routing unprotected signals near the protected D1+/D1−/D2+/D2− paths.
Is the TPD4S009DCKR RoHS compliant and what is its moisture sensitivity level?
Yes, the TPD4S009DCKR is RoHS compliant (lead-free, NiPdAu finish) and rated MSL Level-1 at 260°C peak reflow temperature, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. This MSL rating eliminates moisture-related popcorning risk during standard SMT reflow processes and simplifies manufacturing logistics for high-volume production.
