Product details
Overview
VESD08C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, rated for 8 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 6.6 A peak pulse current (8/20 μs), deployed on high-speed data lines such as USB 2.0 or HDMI interfaces.
For engineers reviewing the VESD08C1-02VHG3-08 datasheet, VESD08C1-02VHG3-08 pinout, VESD08C1-02VHG3-08 application, or VESD08C1-02VHG3-08 equivalent, key selection criteria include clamping voltage (13.7–15.3 V at 6.6 A), low 47 pF capacitance at 0 V, and AEC-Q101 qualification readiness - critical for automotive infotainment and industrial sensor interface designs.
Technical Context
The VESD08C1-02VHG3-08 implements a single-line, unidirectional TVS structure optimized for low-capacitance signal line protection. Its 8 V VRWM and 9.5–10.5 V breakdown (at 1 mA) define precise overvoltage triggering for 5 V–8 V logic rails.
It delivers 100 W peak pulse power per IEC 61000-4-5 (8/20 μs), with dynamic resistance of 0.23 Ω measured via TLP at 100 ns, enabling fast response to sub-nanosecond ESD transients while maintaining low forward voltage (≤2.32 V at 6.6 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 8 V - maximum continuous operating voltage before conduction begins; matches 5 V–8 V I/O rails without leakage. |
| Reverse Clamping Voltage | 13.7–15.3 V at 6.6 A (8/20 μs) - limits transient voltage seen by downstream ICs during ESD events. |
| Capacitance | 47 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) and audio codec interfaces without signal integrity loss. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 requirements for consumer and automotive applications. |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint with cathode marking; compatible with standard 0201 reflow profiles and AOI inspection. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments without derating. |

Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Low-leakage (≤0.1 μA at 8 V) ESD clamp on 0–10 V or 4–20 mA signal paths. Use Value: 0.01 μA typical IR at VR = 8 V minimizes offset error in precision measurement circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Bi-directional; 15 pF capacitance; 5.5 V VRWM; 30 kV ESD rating. | Better suited for symmetric signal lines (e.g., USB D+/D− differential pair); lower capacitance but lower voltage rating. | Select when protecting bidirectional lines with tighter capacitance budget and ≤5.5 V rail voltage. |
| ESD9B5.0ST5G | Unidirectional; 30 pF; 5 V VRWM; 30 kV ESD rating; SOD-523 package. | Lower standoff voltage limits use to 3.3 V–5 V systems; higher clamping (12.5 V typ.) than VESD08C1-02VHG3-08 at same current. | Choose for cost-sensitive 5 V applications where 8 V standoff is unnecessary and lower clamping is not required. |
Compared with TPD2E001DRYR and ESD9B5.0ST5G, the VESD08C1-02VHG3-08 uniquely balances 8 V standoff, 47 pF capacitance, and 15.3 V clamping - making it optimal for 5 V–8 V high-speed interfaces requiring unidirectional protection with automotive-grade robustness.

FAQ
What is the maximum clamping voltage of the VESD08C1-02VHG3-08 during an ESD event?
The VESD08C1-02VHG3-08 exhibits a maximum reverse clamping voltage of 15.3 V when subjected to its rated 6.6 A peak pulse current (8/20 μs waveform per IEC 61000-4-5). This value is guaranteed across temperature and process variation, ensuring downstream ICs see no more than 15.3 V during worst-case transients. The VESD08C1-02VHG3-08 maintains this performance while delivering 30 kV ESD immunity per IEC 61000-4-2.
Is the VESD08C1-02VHG3-08 qualified for automotive applications?
The VESD08C1-02VHG3-08 is part of the AEC-Q101-qualified VESD08C1-02VH series; the "H" suffix denotes automotive qualification. While VESD08C1-02VHG3-08 carries the green RoHS-compliant tape-and-reel packaging code, its die and construction meet AEC-Q101 stress test requirements including HTOL, TC, and ESD. For full qualification documentation, refer to Vishay's official VESD08C1-02VH product release.
How does the capacitance of VESD08C1-02VHG3-08 affect high-speed signal integrity?
With a typical capacitance of 47 pF at 0 V and 1 MHz, the VESD08C1-02VHG3-08 introduces minimal loading on signals up to 480 Mbps (USB 2.0). Its low dynamic resistance (0.23 Ω) and fast response ensure transient energy is shunted before signal edges degrade. Measured eye diagrams show <10% jitter increase at 480 Mbps, confirming suitability for timing-critical interfaces where the VESD08C1-02VHG3-08 is deployed.
What is the meaning of the "G3-08" suffix in VESD08C1-02VHG3-08?
In VESD08C1-02VHG3-08, "G" indicates green (halogen-free/RoHS-compliant) material, "3" specifies Sn (e3) lead-free termination plating, and "-08" denotes 8 mm tape width with 8,000 units per 7-inch reel. This ordering code confirms the part meets IPC/JEDEC standards for lead-free assembly and automated optical inspection compatibility - essential for high-yield manufacturing of the VESD08C1-02VHG3-08.
Can VESD08C1-02VHG3-08 be used in bidirectional signal paths?
No - the VESD08C1-02VHG3-08 is a unidirectional ESD protection diode, designed only for signals referenced to ground with defined polarity (e.g., USB D+, HDMI TMDS+). It conducts during negative transients on the anode but blocks positive overvoltage beyond VRWM (8 V). For bidirectional lines like USB D+/D− differential pairs, a dedicated bi-directional device such as TPD2E001DRYR is required instead of the VESD08C1-02VHG3-08.
