Product details
Overview
VESD03C1-02V-G3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in SOD-523 package, rated for 3 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 11.6 A peak pulse current (8/20 μs), deployed on high-speed USB and HDMI data lines to suppress transient overvoltage.
For engineers reviewing the VESD03C1-02V-G3-08 datasheet, VESD03C1-02V-G3-08 pinout, VESD03C1-02V-G3-08 application, or VESD03C1-02V-G3-08 equivalent, key selection criteria include clamping voltage at rated IPP, dynamic resistance, capacitance at 0 V, reverse leakage at VRWM, and AEC-Q101 qualification status.
Technical Context
This device operates as a single-line, cathode-grounded TVS diode with unidirectional polarity. Its low 89–135 pF capacitance and 0.19 Ω dynamic resistance enable minimal signal distortion on 50 Ω impedance interfaces up to 1 GHz.
The junction is optimized for fast response (<1 ns) to ESD transients per IEC 61000-4-2, delivering clamping within 1 ns of event onset. It sustains repeated ±30 kV discharges without parameter shift and meets MSL level 1 reflow requirements (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 3 V - maximum continuous DC operating voltage before leakage exceeds 20 μA; sets upper limit for protected line voltage. |
| Reverse Clamping Voltage | 7.8–8.7 V at 11.6 A (8/20 μs) - peak voltage seen by downstream IC during worst-case surge; ensures safe margin below IC absolute max ratings. |
| Capacitance | 89–135 pF at 0 V, 1 MHz - low enough to avoid signal integrity degradation on USB 2.0 (480 Mbps) and HDMI 1.4 (3.4 Gbps) channels. |
| Dynamic Resistance | 0.19 Ω - enables rapid voltage collapse during ESD event, minimizing energy dissipation time and thermal stress. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 industrial and automotive ESD robustness requirements. |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint; compatible with standard 0201 pick-and-place and AOI inspection. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments without derating. |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode marked by bar; dimensions 1.3 mm × 0.85 mm × 0.7 mm (L × W × H); weight 1.32 mg; UL 94 V-0 molding compound; MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input side of protected line | Connected to signal trace upstream of IC; carries transient current into diode junction during positive ESD events. |
| Cathode (Pin 2) | Ground reference terminal | Connected to system ground plane; provides low-inductance return path for ESD current; must be routed with minimal loop area. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Enables asymmetric clamping for DC-biased lines (e.g., USB D+, HDMI TMDS+), reducing capacitance vs. bidirectional alternatives. |
| Low 0.7 mm profile | Allows placement beneath connectors or in tight board spaces where height is constrained, such as mobile camera modules. |
| AEC-Q101 qualified option available | Supports automotive infotainment and ADAS subsystems requiring certified reliability; VESD03C1-02V-HG3-08 variant meets this standard. |
| Sn (e3) lead plating | Enables compatibility with lead-free reflow profiles and automated optical inspection (AOI) without solderability compromise. |
| 1.32 mg unit weight | Reduces mechanical stress on fine-pitch traces during thermal cycling; critical for flex-rigid PCBs in wearables and IoT sensors. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines in portable docking stations against user-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver IC, grounded to local chassis ground. Use Value: 89–135 pF capacitance avoids signal rise-time degradation at 480 Mbps; 7.8–8.7 V clamping prevents transceiver latch-up. |

Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins on factory-floor PLC modules subject to maintenance-tool ESD. IC Role / Device Role / Timing Role: Anode connected to transceiver output pin; cathode routed to isolated ground plane to prevent ground bounce coupling. Use Value: 30 kV ESD rating exceeds IEC 61000-6-2 immunity requirement for industrial environments; SOD-523 footprint fits dense I/O headers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9B3.3ST5G (ON Semiconductor) | Same SOD-523 package; 3.3 V VRWM; 12 A IPP; 105 pF typical capacitance; no AEC-Q101 variant offered. | Higher VRWM allows use on 3.3 V logic rails with tighter margin; slightly higher capacitance may affect >1 GHz signals. | Select when 3.3 V rail compatibility is required and AEC-Q101 is not mandated. |
| TPD2E001DRYR (Texas Instruments) | 2-channel array in SOT-553; 3.3 V VRWM; 8 A IPP per channel; 12 pF capacitance; integrated 100 Ω series resistor. | Lower capacitance suits USB 3.0/PCIe Gen1; dual-channel reduces BOM count; series resistor adds signal damping. | Select for multi-line protection where space permits and lower capacitance is critical; not suitable for single-line optimization. |
Compared with ESD9B3.3ST5G, VESD03C1-02V-G3-08 offers tighter clamping (7.8–8.7 V vs. 9.2 V) and AEC-Q101 availability; versus TPD2E001DRYR, it delivers higher surge robustness (11.6 A vs. 8 A) and simpler layout with no series resistance trade-off.

FAQ
What is the maximum reverse stand-off voltage of the VESD03C1-02V-G3-08?
The VESD03C1-02V-G3-08 has a reverse stand-off voltage (VRWM) of 3 V, meaning it remains in high-impedance state up to this DC or repetitive peak voltage. At 3 V, reverse leakage is guaranteed ≤20 μA. This rating makes VESD03C1-02V-G3-08 suitable for protecting 3 V logic and analog signal lines without false triggering.
Does the VESD03C1-02V-G3-08 meet automotive qualification standards?
The base VESD03C1-02V-G3-08 is not AEC-Q101 qualified; however, the variant VESD03C1-02V-HG3-08 is fully AEC-Q101 qualified and shares identical electrical parameters. For automotive applications requiring certified reliability, specify the -H suffix version - VESD03C1-02V-G3-08 remains appropriate for industrial and consumer-grade designs.
What is the clamping voltage of the VESD03C1-02V-G3-08 under a full IEC 61000-4-5 surge?
Under an 8/20 μs IEC 61000-4-5 waveform at its rated peak pulse current of 11.6 A, the VESD03C1-02V-G3-08 clamps to 7.8–8.7 V (typical 8.2 V). This value is measured across the device terminals and represents the maximum voltage imposed on the protected circuit during worst-case surge conditions.
Can the VESD03C1-02V-G3-08 be used on bidirectional signal lines like I²C?
No - the VESD03C1-02V-G3-08 is unidirectional and designed for DC-biased lines (e.g., USB D+, HDMI TMDS+). For bidirectional buses like I²C, a bidirectional ESD diode such as VESD03C2-02V (same family, dual-anode configuration) is required. Using VESD03C1-02V-G3-08 on I²C would block negative half-cycles and disrupt communication.
What is the moisture sensitivity level (MSL) rating for the VESD03C1-02V-G3-08?
The VESD03C1-02V-G3-08 carries an MSL level 1 rating per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60 % RH and may be reflowed using standard lead-free profiles with peak temperature up to 260 °C. No dry-pack or baking is required prior to assembly.
