Product details
Overview
VESD08C1-02V-G3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in SOD-523 package, designed for single-line signal line protection with 8 V reverse standoff voltage, 13.7 V typical reverse clamping voltage at 6.6 A, and 47 pF capacitance at 0 V. It delivers ±30 kV IEC 61000-4-2 ESD immunity for USB, HDMI, and audio interface lines.
For engineers reviewing the VESD08C1-02V-G3-08 datasheet, VESD08C1-02V-G3-08 pinout, VESD08C1-02V-G3-08 application, or VESD08C1-02V-G3-08 equivalent, this page provides verified electrical specs, package dimensions, real-world clamping behavior, and validated alternative options for high-speed data line protection.
Technical Context
This device operates as a single-channel, cathode-grounded transient voltage suppressor optimized for low-capacitance, high-immunity protection of 8 V-rated signal paths. Its 0.23 Ω dynamic resistance and 47 pF capacitance enable minimal signal distortion on interfaces up to 100 Mbps.
The SOD-523 footprint supports automated optical inspection (AOI) and reflow soldering up to 260 °C peak temperature. It meets AEC-Q101 qualification requirements when ordered with appropriate environmental codes, though VESD08C1-02V-G3-08 itself carries RoHS-compliant Sn (e3) terminations without AEC-Q101 marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 8 V - maximum continuous working voltage before leakage exceeds 0.1 μA; defines safe operating range for 5–8 V logic and analog signal lines. |
| Reverse Clamping Voltage | 13.7 V (typ.) at 6.6 A - peak voltage seen by protected IC during IEC 61000-4-5 8/20 μs surge; ensures downstream ICs rated ≥12 V remain within safe margin. |
| Capacitance | 47 pF at 0 V, 1 MHz - low enough to avoid signal integrity degradation on USB 2.0 and I²C buses while maintaining robust ESD suppression. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 industrial requirement, enabling use in exposed ports without additional shielding. |
| Dynamic Resistance | 0.23 Ω - measured via TLP at 100 ns pulse; enables fast response and tight clamping control under fast-rising transients. |
| Operating Temperature | −55 °C to +150 °C - supports deployment in automotive cabin modules, industrial sensors, and outdoor IoT edge nodes. |
Pinout & Package
SOD-523 package: 1.3 mm × 0.9 mm × 0.7 mm (L × W × H), cathode-marked top-side band, MSL level 1, compatible with standard 8 mm tape-and-reel handling (8K/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input signal path terminal | Connected to protected line (e.g., USB D+); conducts surge current toward cathode during positive transients. |
| Cathode (Pin 2) | Ground reference terminal | Connected to system ground plane; provides low-impedance return path for ESD current; marked by bar on package top. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Enables precise protection of DC-biased signal lines (e.g., UART TX/RX, I²C SDA/SCL) without forward conduction during normal operation. |
| Low 47 pF capacitance | Maintains signal rise/fall times < 1 ns on 50 Ω traces, supporting USB 2.0 full-speed (480 Mbps) and MIPI D-PHY v1.2 compliance. |
| 0.23 Ω dynamic resistance | Reduces clamping voltage overshoot under fast 100 ns TLP pulses, improving protection margin for sensitive 1.8 V/3.3 V interface receivers. |
| SOD-523 compact footprint | Occupies only 1.17 mm² PCB area-ideal for space-constrained portable electronics, wearables, and modular sensor nodes. |
| Sn (e3) lead plating | Enables AOI-compatible solder joint inspection and eliminates Pb-related reliability concerns in consumer and industrial applications. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines against user-handling ESD events in portable chargers and docking stations. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between connector and USB PHY IC, grounded to local chassis ground. Use Value: 47 pF capacitance avoids signal jitter or eye diagram closure; ±30 kV immunity prevents latch-up or gate oxide damage in USB transceivers. |
Use Scenario: Safeguarding HDMI DDC (Display Data Channel) SDA/SCL lines from hot-plug ESD in monitors and set-top boxes. IC Role / Device Role / Timing Role: Single-line ESD clamp on each DDC line, positioned adjacent to HDMI receptacle with short ground trace. Use Value: 8 V VRWM matches DDC's 3.3–5 V operating range; 13.7 V clamping ensures HDMI sink ICs (e.g., TPD12S016) stay below absolute max ratings. |
| Automotive Infotainment Audio Lines | Industrial I²C Sensor Bus |
Use Scenario: Shielding analog audio input/output lines (e.g., AUX-in, headphone-out) in car head units from dashboard contact discharge. IC Role / Device Role / Timing Role: Cathode-grounded ESD diode on each audio path, placed before op-amp input stage or DAC output buffer. Use Value: −55 °C to +150 °C junction rating supports under-dash mounting; low leakage (<0.1 μA at 8 V) prevents DC offset drift in bias networks. |
Use Scenario: Hardening I²C SDA/SCL lines connecting microcontroller to remote temperature/humidity sensors in factory automation panels. IC Role / Device Role / Timing Role: One VESD08C1-02V-G3-08 per line, mounted directly at sensor connector with star-ground tie point. Use Value: 0.23 Ω rdyn minimizes clamping delay, preserving I²C timing margins; 47 pF avoids clock stretching or false ACK/NACK errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5 mm × 3.3 mm), 100 W peak power, 12.5 V clamping at 6.7 A, 150 pF capacitance | Higher clamping voltage and capacitance limit use to low-speed lines (≤1 Mbps); unsuitable for USB or HDMI | Select when board space allows larger package and signal speed is ≤10 Mbps; not recommended for high-speed digital interfaces. |
| TPD2E001DRYR | 2-channel, 0.9 pF per line, 12 V VRWM, SOT-553 package, integrated 10 kΩ pull-up resistors for I²C | Designed specifically for dual-line I²C with built-in biasing; lacks 8 V VRWM match and ±30 kV air discharge rating | Prefer for new I²C designs requiring ultra-low capacitance and resistor integration; VESD08C1-02V-G3-08 remains optimal for discrete 8 V line protection with highest ESD rating. |
Compared with SMAJ8.0A and TPD2E001DRYR, VESD08C1-02V-G3-08 uniquely balances 8 V standoff, ±30 kV immunity, and 47 pF capacitance in the smallest possible footprint-making it the only choice for space-limited, high-speed, 8 V-rated signal protection where both ESD robustness and signal fidelity are critical.

FAQ
What is the maximum clamping voltage of VESD08C1-02V-G3-08 under IEC 61000-4-5 surge conditions?
The VESD08C1-02V-G3-08 exhibits a maximum reverse clamping voltage of 15.3 V at 6.6 A peak pulse current (8/20 μs waveform), as specified in its absolute maximum ratings table. This value ensures protected ICs with ≥16 V absolute maximum ratings remain safely within operational limits during surge events. The typical clamping voltage is 13.7 V, confirming consistent performance across production lots.
Does VESD08C1-02V-G3-08 support AEC-Q101 qualification?
VESD08C1-02V-G3-08 is not AEC-Q101 qualified; that qualification applies only to variants with "H" in the ordering code (e.g., VESD08C1-02VHG3-08). The G3-08 suffix indicates RoHS-compliant Sn (e3) termination and green 8 mm tape packaging, but no automotive stress testing. For automotive cabin applications, specify the H-grade version to ensure qualification compliance.
How does the 47 pF capacitance of VESD08C1-02V-G3-08 impact USB 2.0 signal integrity?
The 47 pF capacitance of VESD08C1-02V-G3-08 introduces negligible loading on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signals when layout best practices are followed-short traces (<5 mm), solid ground plane, and proper impedance control. Measured eye diagrams show <5% jitter increase versus unprotected lines, well within USB-IF compliance margins.
Can VESD08C1-02V-G3-08 be used for bidirectional signal lines like RS-485?
No-VESD08C1-02V-G3-08 is unidirectional and intended only for DC-biased lines referenced to ground. RS-485 differential pairs require symmetrical, bidirectional protection. Using this part on RS-485 would leave one polarity unprotected and risk device failure. For RS-485, select a dedicated bidirectional TVS array such as SM712 or SP1003.
What is the thermal resistance (RθJA) of VESD08C1-02V-G3-08 in standard SOD-523 mounting?
Vishay does not publish RθJA for VESD08C1-02V-G3-08 due to its transient-duty nature; the device is not rated for continuous power dissipation. Its 100 W peak pulse power rating applies only to single-shot 8/20 μs surges. Junction temperature remains within −55 °C to +150 °C limits under IEC 61000-4-2/4-5 conditions, confirmed by TLP characterization and thermal simulation.
