Product details
Overview
VESD03C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, designed for single-line signal line protection with 3 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 11.6 A peak pulse current handling-used in USB, HDMI, and low-voltage sensor interfaces.
For engineers reviewing the VESD03C1-02VHG3-08 datasheet, VESD03C1-02VHG3-08 pinout, VESD03C1-02VHG3-08 application, or VESD03C1-02VHG3-08 equivalent, key selection criteria include clamping voltage (≤8.7 V at 11.6 A), capacitance (112 pF typical), dynamic resistance (0.19 Ω), operating temperature range (−55 °C to +150 °C), and AEC-Q101 qualification status.
Technical Context
The VESD03C1-02VHG3-08 implements a single-channel, unidirectional TVS structure optimized for fast transient suppression on low-voltage data lines. Its silicon avalanche junction delivers precise breakdown at 4.65 V (typ.) and clamps transients within 8.7 V at full 11.6 A IEC 61000-4-5 surge current.
Designed for high-density PCB layouts, it features ultra-low profile (<0.7 mm height) and low parasitic capacitance (112 pF typ. at 0 V), enabling use in high-speed interfaces without signal integrity degradation. The device meets AEC-Q101 stress testing requirements for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3 V - maximum continuous working voltage before conduction begins; defines safe operating margin for 3.3 V logic rails. |
| Reverse Breakdown Voltage | 4.65 V (typ.) - precise avalanche onset ensures early clamping during ESD events without false triggering. |
| Clamping Voltage | 8.7 V max at 11.6 A - limits downstream IC voltage stress during IEC 61000-4-5 surges, protecting 5 V tolerant receivers. |
| Capacitance | 112 pF (typ. at 0 V, 1 MHz) - low enough for USB 2.0 and I²C signal integrity; avoids timing skew or attenuation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 industrial and automotive system requirements. |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint enables placement adjacent to connectors with minimal board area usage. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive, industrial control, and extended-temperature IoT deployments. |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode marking bar; dimensions 1.3 mm × 0.85 mm × 0.7 mm (L × W × H); MSL level 1; compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input signal path terminal | Connected to protected line (e.g., USB D+); conducts during positive transients when cathode is biased higher. |
| Cathode (Pin 2) | Ground reference terminal | Connected to system ground; provides low-impedance path for ESD current diversion during negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD Protection | Enables asymmetric clamping optimized for grounded-signal architectures like USB and UART, reducing leakage vs. bidirectional devices. |
| AEC-Q101 Qualified | Validated for automotive applications including infotainment, body electronics, and ADAS sensor interfaces per stress test requirements. |
| Low Dynamic Resistance | 0.19 Ω (TLP, 100 ns) ensures rapid voltage collapse during ESD, minimizing energy delivered to protected ICs. |
| Sn (e3) Lead Finish | Tin plating enables AOI-compatible solder joint inspection and eliminates lead-free process compatibility concerns. |
| Compact SOD-523 Footprint | Reduces PCB real estate by >50% vs. SOD-323, critical for space-constrained portable and wearable designs. |
Applications
| USB 2.0 Interface Protection | HDMI Data Line Protection |
|---|---|
Use Scenario: Protecting USB D+/D− lines in portable media players against user-handling ESD events. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed directly at connector entry point. Use Value: Clamps 30 kV contact discharge to ≤8.7 V while adding only 112 pF capacitance-preserving eye diagram integrity at 480 Mbps. |
Use Scenario: Safeguarding HDMI TMDS channels in set-top boxes exposed to repeated hot-plug insertion events. IC Role / Device Role / Timing Role: Point-of-entry ESD clamp on each differential pair, referenced to chassis ground.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G (ON Semiconductor) | Same SOD-523 package, 3.3 V VRWM, 12.5 V VC max at 9.5 A; 105 pF capacitance. | Lower clamping voltage but reduced surge rating; suitable for lower-energy interfaces like GPIO. | Select when tighter clamping (<12.5 V) is prioritized over peak current handling (11.6 A). |
| TPD2E001DRYR (Texas Instruments) | 2-channel bidirectional array in SOT-553; 3.6 V VRWM; 12 V VC max at 4 A; 11 pF per channel. | Higher integration (dual line), much lower capacitance-but requires separate ground routing and lacks AEC-Q101 rating. | Choose for space-constrained dual-line protection where ultra-low capacitance (<15 pF) is mandatory and automotive qualification is not required. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, the VESD03C1-02VHG3-08 offers superior single-line surge robustness (11.6 A IPPM) and automotive qualification, making it optimal for high-reliability 3 V rail protection where moderate capacitance is acceptable.

FAQ
What is the maximum clamping voltage of the VESD03C1-02VHG3-08 during an ESD event?
The VESD03C1-02VHG3-08 has a maximum reverse clamping voltage of 8.70 V at 11.6 A peak pulse current (IEC 61000-4-5, 8/20 μs waveform). This value ensures downstream 3.3 V or 5 V ICs remain within safe absolute maximum ratings during transient events. The clamping performance is verified per standardized TLP testing with 100 ns pulse width.
Is the VESD03C1-02VHG3-08 qualified for automotive applications?
Yes, the VESD03C1-02VHG3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronics. Its −55 °C to +150 °C operating range and SOD-523 package make it suitable for under-hood and cabin-mounted ECUs.
What does the "HG3-08" suffix in VESD03C1-02VHG3-08 indicate?
The "HG3-08" suffix denotes RoHS-compliant + lead (Pb)-free terminations (H), green molding compound (G), Sn (e3) plating (3), and packaging in 8 mm tape on 7-inch reel with 8,000 units per reel (08). This matches Vishay's standardized ordering code format for SOD-523 ESD diodes.
Can the VESD03C1-02VHG3-08 be used on bidirectional data lines like RS-485?
No-the VESD03C1-02VHG3-08 is unidirectional and intended for grounded-signal applications such as USB or I²C. For bidirectional lines like RS-485, a symmetric (bidirectional) ESD protector-e.g., VESD05C1-02V or equivalent-is required to clamp both polarities equally without forward conduction during normal operation.
How does the capacitance of VESD03C1-02VHG3-08 affect high-speed signal integrity?
The VESD03C1-02VHG3-08 exhibits 112 pF typical capacitance at 0 V bias and 1 MHz, which is well-suited for USB 2.0 (480 Mbps) and I²C (400 kHz) but may limit usability in >1 Gbps interfaces. Its low dynamic resistance (0.19 Ω) minimizes distortion during fast transients, preserving signal edge fidelity in protected lines.
