Product details
Overview
VESD01C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in SOD-523 package, rated for 1 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 11 A peak pulse current (8/20 μs), designed for protecting low-voltage signal lines in portable electronics.
For engineers reviewing the VESD01C1-02VHG3-08 datasheet, VESD01C1-02VHG3-08 pinout, VESD01C1-02VHG3-08 application, or VESD01C1-02VHG3-08 equivalent, key selection criteria include clamping voltage (≤6.4 V at 11 A), ultra-low capacitance (153–230 pF), compact height (<0.7 mm), AEC-Q101 qualification readiness, and compatibility with automated optical inspection (AOI) due to Sn (e3) lead plating.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance, high-speed data line protection. Its 1 V VRWM enables integration on 1.2 V or 1.8 V I/O rails without leakage-induced bias shift, while dynamic resistance of 0.13 Ω (TLP, 100 ns) ensures rapid voltage clamping during sub-nanosecond ESD transients.
The SOD-523 footprint supports high-density PCB layouts in space-constrained applications such as USB 2.0, HDMI DDC, and I²C interfaces. Its MSL level 1 rating and peak reflow tolerance up to 260 °C support standard lead-free assembly processes without preconditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9B1.0ST5G (ON Semiconductor) | Same SOD-523 package; 1 V VRWM; 30 kV ESD rating; but higher typical capacitance (250 pF) and lower PPP (50 W). | Less suitable for >50 Mbps data lines due to higher CD; acceptable for low-speed GPIO or reset lines. | Select when cost sensitivity outweighs marginal speed requirements and legacy design reuse is prioritized. |
| TPD1E10B06DPYR (Texas Instruments) | Same 1 V VRWM and SOD-523; lower clamping (≤5.5 V at 8 A); lower capacitance (12 pF typ); but lower IPPM (8 A) and non-AEC-Q101 qualified. | Better for high-speed analog or RF-adjacent lines; not recommended for automotive under-hood or infotainment modules requiring AEC-Q101. | Prefer for portable medical sensors or audio codec interfaces where ultra-low CD dominates over peak surge margin. |
Compared with ESD9B1.0ST5G and TPD1E10B06DPYR, VESD01C1-02VHG3-08 delivers superior peak power handling (70 W vs. ≤50 W), tighter clamping control (6.4 V max vs. ≥7.5 V), and explicit AEC-Q101 qualification pathway-making it optimal for automotive infotainment and industrial handhelds demanding both robustness and long-term supply assurance.

FAQ
What is the maximum clamping voltage of VESD01C1-02VHG3-08 under IEC 61000-4-5 surge conditions?
The VESD01C1-02VHG3-08 exhibits a maximum reverse clamping voltage of 6.4 V when subjected to an 11 A peak pulse current with an 8/20 μs waveform per IEC 61000-4-5. This value is measured at the device terminals and defines the upper bound of transient overvoltage imposed on downstream circuitry during surge events. The VESD01C1-02VHG3-08 maintains this performance across its full operating temperature range of -55 °C to +150 °C.
Is VESD01C1-02VHG3-08 qualified to AEC-Q101 standards?
VESD01C1-02VHG3-08 is part of the VESDxxC1-02V family, which offers AEC-Q101-qualified variants (denoted by "H" in the ordering code). While the specific suffix "HG3-08" indicates RoHS-compliant Sn (e3) plating and 8 mm tape/reel packaging, AEC-Q101 qualification applies to the base VESD01C1-02V die and construction-confirmed in Vishay's documentation as "AEC-Q101 qualified available". Full qualification testing is performed on the same process and package used in VESD01C1-02VHG3-08.
How does the capacitance of VESD01C1-02VHG3-08 affect high-speed signal integrity?
The VESD01C1-02VHG3-08 has a typical capacitance of 192 pF (range 153–230 pF at 0 V, 1 MHz), which introduces minimal loading on low-to-moderate speed digital lines. For USB 2.0 (480 Mbps), this capacitance results in < 0.5 dB attenuation at Nyquist frequency and preserves eye diagram opening. It is not recommended for >1 Gbps differential interfaces like USB 3.0 or PCIe, where sub-1 pF devices are required. The VESD01C1-02VHG3-08 is optimized for 10–100 Mbps applications including I²C, UART, and DDC.
Can VESD01C1-02VHG3-08 be used in bidirectional signal paths?
No-VESD01C1-02VHG3-08 is a unidirectional ESD protection diode, configured with anode and cathode terminals for single-polarity clamping. It must be oriented with cathode tied to ground and anode to the protected line. For bidirectional interfaces such as USB D+/D− or RS-485, two VESD01C1-02VHG3-08 devices (one per line) or a dedicated bidirectional array like VESD05C1-02V would be required. Using VESD01C1-02VHG3-08 in reverse orientation risks permanent breakdown.
What is the moisture sensitivity level (MSL) rating for VESD01C1-02VHG3-08?
VESD01C1-02VHG3-08 is rated MSL level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60% RH and requires no dry-packaging or baking prior to surface-mount assembly. This simplifies inventory management and eliminates reflow-related delamination risk. The SOD-523 package's low mass (1.32 mg) and UL 94 V-0 molding compound contribute to this robust moisture resistance, making VESD01C1-02VHG3-08 ideal for just-in-time manufacturing environments.
