Product details
Overview
TPD4S009DGSR from Texas Instruments is a 10-pin VSSOP-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, 10 nA typical leakage current at 3.3 V, 2.5 A IEC 61000-4-5 surge rating (8/20 µs), and supports >4 GHz bandwidth-enabling robust protection for HDMI 1.4 and USB 2.0 data lines without signal integrity degradation.
For engineers reviewing the TPD4S009DGSR datasheet, TPD4S009DGSR pinout, TPD4S009DGSR application, or TPD4S009DGSR equivalent, key selection criteria include its flow-through routing capability, ultra-low differential pair capacitance matching (0.05 pF line-line), Ioff functionality enabled by the VCC pin, industrial temperature range (–40°C to 85°C), and compatibility with high-speed differential layouts requiring minimal trace length mismatch.
Technical Context
The TPD4S009DGSR integrates four matched bidirectional TVS clamps in a monolithic silicon structure, each protecting one differential signal pair (D1+/D1−, D2+/D2−). Its internal architecture includes a central clamp biased via the optional VCC pin, enabling the Ioff feature that maintains protection during system power-off states-critical for HDMI hot-plug compliance.
It operates passively without supply power but leverages the VCC pin to stabilize internal node potentials during startup; this does not affect ESD performance. Triggering occurs when I/O voltage exceeds ±9 V breakdown (VBR) or drops below –0.6 V forward conduction, diverting ESD current to GND within nanoseconds while clamping voltage to safe levels for downstream ICs.
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 immunity against human-body ESD events at connector interfaces. |
| Surge Rating | 2.5 A peak pulse (8/20 µs) per IEC 61000-4-5-handles transient surges from cable coupling or lightning-induced transients. |
| I/O Capacitance | 0.8 pF typical per pin to GND-minimizes signal distortion and insertion loss for 3.4 Gbps HDMI 1.4 and USB 2.0 data rates. |
| Line-to-Line Matching | 0.05 pF capacitance mismatch between D1+/D1− and D2+/D2−-preserves differential skew and common-mode rejection in high-speed links. |
| Breakdown Voltage | 9 V minimum (IIO = 1 mA)-provides margin above 5.5 V maximum signal swing while ensuring reliable clamping onset. |
| Leakage Current | 10 nA typical at 3.3 V IO bias-prevents DC loading of sensitive receiver inputs and avoids false triggering in low-power modes. |
| Operating Temperature | –40°C to +85°C-supports deployment in industrial, consumer, and embedded computing environments without derating. |
Pinout & Package
VSSOP (DGS) package: 10-pin, 3.00 mm × 3.00 mm body size, 1.1 mm max height, gull-wing leads, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D1+ | Positive terminal of first differential channel-connects to high-speed signal line (e.g., HDMI TMDS D1+ or USB D+). |
| 2 | GND | Primary ground reference for ESD current return path-must be low-inductance connection to system GND plane. |
| 3 | D1− | Negative terminal of first differential channel-paired with Pin 1 to maintain impedance and timing symmetry. |
| 4 | D2+ | Positive terminal of second differential channel-used for parallel interface protection (e.g., HDMI TMDS D2+ or USB D−). |
| 5 | GND | Secondary ground pin-enhances current distribution and reduces ground bounce during multi-pin ESD events. |
| 6 | D2− | Negative terminal of second differential channel-mirrors Pin 4 to preserve differential pair integrity and capacitance matching. |
| 7 | VCC | Optional supply bias pin-enables Ioff functionality; connects to system VCC (0.9–5.5 V) to stabilize internal clamp nodes during power sequencing. |
| 8 | GND | Third ground pin-further lowers thermal and electrical impedance for high-current ESD dissipation. |
| 9 | N.C. | No internal connection-left unconnected; no routing or soldering required. |
| 10 | N.C. | No internal connection-left unconnected; no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Ioff functionality with VCC pin | Enables live-signal protection during system power-off-critical for HDMI hot-plug detection where D+/D− may be active before VCC ramps. |
| Flow-through board layout | Pin 1→3→4→6 signal path allows straight trace routing across device-reduces stubs, impedance discontinuities, and inter-pair skew in differential layouts. |
| Ultra-low differential capacitance matching | 0.05 pF line-to-line capacitance mismatch ensures <0.1 ps intra-pair skew-maintains eye diagram integrity at 1.7 GHz HDMI clock frequencies. |
| Passive operation without supply | Functions fully without VCC connection-simplifies design in systems where supply rail is unavailable or noisy during ESD events. |
| Industrial temperature range | Validated operation from –40°C to +85°C-eliminates need for thermal derating in set-top boxes, DTAs, and industrial displays. |
Applications

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-but lacks Ioff functionality and uses different pinout (no dedicated VCC/GND redundancy). | Suitable for USB 2.0 or HDMI where system always powers VCC before signal assertion; not viable for hot-plug-critical HDMI sinks. | Select when board layout prioritizes smallest footprint (2.50 mm × 1.00 mm) and Ioff is unnecessary. |
| TPD4E05U06DQAR | 10-pin USON, P2P compatible with TPD4S010DQAR, higher ±12-kV contact ESD rating, lower 0.5 pF capacitance, lower clamping voltage (VD = 0.55 V typ), but no VCC pin or Ioff. | Better suited for next-gen USB 3.0 or MIPI D-PHY interfaces demanding tighter capacitance and lower clamping-requires redesign if replacing TPD4S009DGSR directly. | Select when upgrading ESD robustness beyond IEC Level 4 or extending bandwidth margin for future interfaces. |
Compared with TPD4S010DQAR and TPD4E05U06DQAR, the TPD4S009DGSR uniquely provides Ioff-enabled hot-plug protection in a VSSOP package with triple-GND pins for superior thermal and ESD current handling-making it optimal for HDMI 1.4 sink applications where power sequencing is uncontrolled.

FAQ
What is the primary function of the VCC pin on the TPD4S009DGSR?
The VCC pin on the TPD4S009DGSR enables the Ioff feature, allowing the device to protect live signals on D1+/D1− and D2+/D2− even when system power is off. When connected to a valid supply (0.9–5.5 V), it biases internal clamp nodes to known potentials during power-up sequencing-ensuring predictable ESD response without affecting the TPD4S009DGSR's core protection performance.
Does the TPD4S009DGSR require external power to operate?
No-the TPD4S009DGSR functions as a passive TVS diode array and requires no external power to provide ESD protection. The VCC pin is optional and used only to activate the Ioff feature; leaving it unconnected does not impair the TPD4S009DGSR's ability to clamp ±8-kV ESD strikes or 2.5 A surges.
How does the TPD4S009DGSR differ from the TPD4S010DQAR in terms of pin configuration?
The TPD4S009DGSR (VSSOP-10) includes a dedicated VCC pin (Pin 7) and three GND pins (Pins 2, 5, 8), supporting Ioff and enhanced current handling. The TPD4S010DQAR (USON-10) has no VCC pin and uses a different pinout-making them not pin-compatible. Both protect two differential pairs but differ in biasing architecture and thermal design.
Can the TPD4S009DGSR be used for HDMI 2.0 or higher interfaces?
The TPD4S009DGSR is specified for >4 GHz bandwidth and 3.4 Gbps data rates, aligning with HDMI 1.4. While its 0.8 pF capacitance and low skew support marginal HDMI 2.0 (6 Gbps) operation in short-reach applications, TI does not characterize or guarantee performance beyond HDMI 1.4-so the TPD4S009DGSR should not be assumed compliant for full HDMI 2.0/2.1 use cases without system-level validation.
What is the significance of the 0.05 pF line-to-line capacitance matching in the TPD4S009DGSR?
The 0.05 pF line-to-line capacitance matching between D1+/D1− and D2+/D2− minimizes intra-pair and inter-pair skew-critical for maintaining differential signal integrity in HDMI 1.4. This tight matching ensures consistent propagation delay across both channels, preserving eye diagram opening and reducing jitter-induced bit errors during ESD transients.
