Product details
Overview
VESD05C1-02V-G3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, designed for single-line signal line protection with 5 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 10.3–11.5 V clamping at 8.7 A peak pulse current. It serves in USB 2.0, HDMI, and low-voltage I/O interfaces where space-constrained board layout and high ESD robustness are critical.
For engineers reviewing the VESD05C1-02V-G3-08 datasheet, VESD05C1-02V-G3-08 pinout, VESD05C1-02V-G3-08 application, or VESD05C1-02V-G3-08 equivalent, key selection factors include its 67 pF typical capacitance at 0 V, 0.2 Ω dynamic resistance, sub-0.7 mm height, AEC-Q101 qualification option, and compatibility with automated optical inspection (AOI) due to Sn (e3) lead plating.
Technical Context
This device implements a single-channel, cathode-grounded unidirectional TVS structure optimized for fast transient suppression on low-voltage data lines. Its clamping behavior is characterized by a 7.26 V typical breakdown voltage (at 1 mA), 10.3–11.5 V reverse clamping at 8.7 A (8/20 μs), and <0.1 μA leakage at 5 V working voltage.
The SOD-523 footprint supports high-density routing with 1.3 mm × 0.85 mm body size and 0.18 mm nominal cathode stripe width. Thermal performance is rated for junction temperatures from –55 °C to +150 °C, with MSL level 1 moisture sensitivity and peak reflow tolerance up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC operating voltage before significant leakage; defines upper limit for protected signal swing. |
| Reverse Clamping Voltage | 10.3–11.5 V at 8.7 A (8/20 μs) - Peak voltage seen by downstream IC during worst-case surge; ensures safe margin below 5 V logic rail limits. |

Applications
| USB 2.0 Interface Protection | HDMI 1.4 Data Lane Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against user-handling ESD in smartphones, docking stations, and peripherals. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver IC, referenced to system ground. Use Value: 67 pF capacitance preserves signal rise/fall times; 30 kV ESD immunity exceeds IEC 61000-4-2 Level 4 requirement without degrading eye diagram. |
Use Scenario: Safeguarding TMDS clock and data channels in HDMI 1.4 sources (e.g., set-top boxes, media players) exposed to hot-plug and handling events. IC Role / Device Role / Timing Role: Line-to-ground ESD suppressor on each differential pair, leveraging low dynamic resistance to minimize clamping delay. Use Value: Sub-0.7 mm height avoids interference with HDMI connector shrouds; 11.5 V max clamping stays well below HDMI receiver absolute maximum ratings. |
| Automotive Infotainment I/O | Industrial Sensor Interface |
|
Use Scenario: Protecting UART, I²C, or analog audio lines in automotive head units and display modules subjected to ISO 10605 and IEC 61000-4-2 testing. IC Role / Device Role / Timing Role: Single-line ESD clamp on low-speed control signals routed across PCB flex cables or connectors. Use Value: AEC-Q101 qualified variant (G3) ensures reliability under thermal cycling and vibration; –55 °C to +150 °C operation covers full vehicle ambient range. |
Use Scenario: Shielding 4–20 mA loop inputs, RS-485 transceivers, or analog sensor outputs in factory automation PLCs and field instruments. IC Role / Device Role / Timing Role: Ground-referenced transient suppressor on signal input pins, selected for low leakage (<0.1 μA at 5 V) to avoid offset errors. Use Value: 0.1 μA max reverse current at VRWM prevents loading of high-impedance sensor circuits; 100 W peak power rating handles lightning-induced surges per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.65 pF lower typical capacitance (66.4 pF), same 5 V VRWM, but only ±15 kV IEC 61000-4-2 contact discharge rating. | Preferred for ultra-high-speed USB 3.0 Gen1 lanes where sub-67 pF is critical; not suitable for automotive or industrial ESD test compliance. | Select TPD2E001DRYR only when ESD immunity ≥±30 kV is not required and capacitance budget is tighter than 0.5 pF. |
| ESD5Z5.0T1G | Same SOD-523 package and 5 V VRWM, but 12.5 V max clamping at 8.7 A and 90 pF typical capacitance - higher clamping and capacitance than VESD05C1-02V-G3-08. | Used in cost-sensitive consumer electronics where moderate ESD margin and relaxed signal integrity are acceptable. | Choose ESD5Z5.0T1G only if design tolerates 1.2 V higher clamping voltage and 23 pF higher capacitance; verify signal integrity impact on target interface. |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, VESD05C1-02V-G3-08 delivers superior ESD immunity (±30 kV), lower clamping voltage (10.3–11.5 V), and optimized capacitance (53–81 pF) for automotive-grade USB/HDMI protection - making it the preferred choice where system-level compliance and signal fidelity are jointly mandated.

FAQ
What is the maximum clamping voltage of the VESD05C1-02V-G3-08 during an 8.7 A ESD event?
The VESD05C1-02V-G3-08 exhibits a maximum reverse clamping voltage of 11.5 V when subjected to an 8.7 A peak pulse current with an 8/20 μs waveform per IEC 61000-4-5. This value is measured at the device terminals and represents the highest voltage imposed on the protected line during worst-case surge conditions. The VESD05C1-02V-G3-08 maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is the VESD05C1-02V-G3-08 qualified to AEC-Q101 standards?
Yes, the VESD05C1-02V-G3-08 is offered in an AEC-Q101 qualified version - the "G3" suffix explicitly denotes qualification per AEC-Q101-001 for stress testing including HTRB, HTGB, and temperature cycling. This makes the VESD05C1-02V-G3-08 suitable for automotive applications such as infotainment systems and ADAS sensor interfaces where component reliability under thermal and mechanical stress is mandatory.
What is the typical capacitance of the VESD05C1-02V-G3-08 and how does it affect high-speed signal lines?
The VESD05C1-02V-G3-08 has a typical capacitance of 67 pF at 0 V and 1 MHz, with a guaranteed range of 53–81 pF. This low capacitance enables use on USB 2.0 (480 Mbps) and HDMI 1.4 data lanes without measurable signal integrity degradation, as confirmed by Vishay's application data. The VESD05C1-02V-G3-08 achieves this while maintaining ±30 kV ESD immunity - a balance not matched by many competing 5 V-rated diodes.
Can the VESD05C1-02V-G3-08 be used in bidirectional signal paths like RS-485?
No, the VESD05C1-02V-G3-08 is a unidirectional ESD protection diode and must be used only on signals referenced to ground - such as USB D+, HDMI TMDS+, or single-ended UART TX. For true bidirectional lines like RS-485 differential pairs, a symmetric (bidirectional) TVS array such as VESD0505B1-02V is required. Using the VESD05C1-02V-G3-08 on a floating or AC-coupled line risks forward conduction and signal distortion.
What is the moisture sensitivity level (MSL) and reflow profile for the VESD05C1-02V-G3-08?
The VESD05C1-02V-G3-08 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard Pb-free reflow profiles without pre-baking. Its peak reflow temperature tolerance is 260 °C maximum, compatible with industry-standard JEDEC J-STD-020-compliant thermal profiles. The SOD-523 package and Sn (e3) terminations ensure reliable solder joint formation and AOI compatibility in high-volume SMT assembly of the VESD05C1-02V-G3-08.
