Product details
Overview
VESD03A2-03GHG3-08 from Vishay Semiconductors is a dual-line unidirectional ESD-protection diode array in SOT-323 package, rated for 3 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 100 W peak pulse power. It protects two signal lines in high-speed interfaces such as USB 2.0, HDMI, or automotive infotainment data buses.
For engineers reviewing the VESD03A2-03GHG3-08 datasheet, VESD03A2-03GHG3-08 pinout, VESD03A2-03GHG3-08 application, or VESD03A2-03GHG3-08 equivalent, this page delivers verified electrical parameters, SOT-323 terminal mapping, real-world clamping behavior at 11.6 A, capacitance (89–135 pF), and AEC-Q101-qualified alternatives for automotive-grade designs.
Technical Context
This device implements two independent unidirectional TVS diodes in a single SOT-323 package, with common cathode configuration (pin 3) and separate anodes (pins 1 and 2). Its low dynamic resistance (0.19 Ω typ) ensures fast response to ESD transients while maintaining low clamping voltage (7.8–8.7 V at 11.6 A).
Designed for I/O line protection in space-constrained applications, it operates across -55 °C to +150 °C junction temperature and meets AEC-Q101 stress test requirements when ordered with 'H' qualification code. The Sn (e3) lead finish supports standard reflow and AOI inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 3 V - Maximum continuous working voltage before leakage exceeds 20 μA; sets upper limit for protected signal swing. |
| Reverse Breakdown Voltage | 4.4–4.9 V at 1 mA - Confirmed turn-on threshold ensuring reliable clamping onset during ESD events. |
| Reverse Clamping Voltage | 7.8–8.7 V at 11.6 A, 8/20 μs - Peak voltage seen by downstream circuitry during worst-case surge; critical for IC input tolerance margin. |
| Capacitance | 89–135 pF at 0 V, 1 MHz - Measured signal-line loading affecting high-speed integrity (e.g., < 480 Mbps USB 2.0 eye margin). |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Validated robustness against human-body-model discharges in industrial and automotive environments. |
| Peak Pulse Power | 100 W per line, 8/20 μs - Sustains transient energy without degradation; exceeds IEC 61000-4-5 Level 3 requirement. |
| Operating Temperature | -55 °C to +150 °C - Enables deployment in under-hood automotive ECUs and industrial control modules. |
Pinout & Package
SOT-323 package (JEDEC TO-236AB), 3-terminal surface-mount plastic case with 1.3 mm × 1.8 mm footprint, 0.65 mm pitch, MSL level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first protected line; connects to signal trace upstream of IC input. |
| 2 | Anode 2 | Input terminal for second protected line; electrically isolated from pin 1, shares cathode. |
| 3 | Cathode (common) | Ground reference node for both protection paths; must be low-inductance connection to system ground plane. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF3.3A-T | Single-line SOD-123 package; 3.3 V VRWM; 12.5 V VC at 12.5 A; 150 pF capacitance. | Requires two devices for dual-line protection; higher capacitance limits use in >100 Mbps interfaces. | Select when board layout allows discrete placement and cost sensitivity outweighs space constraints. |

The VESD03A2-03GHG3-08 is rated for 11.6 A peak pulse current per line under IEC 61000-4-5 8/20 μs waveform conditions. This value is measured between either pin 1–3 or pin 2–3, confirming its ability to safely divert ESD surges without failure while maintaining clamping voltage below 8.7 V.
Does VESD03A2-03GHG3-08 meet automotive qualification standards?
Yes, VESD03A2-03GHG3-08 includes the 'H' suffix indicating AEC-Q101 qualification. This certification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness-validating its suitability for automotive infotainment, body control, and ADAS subsystems.
What is the typical capacitance of VESD03A2-03GHG3-08 and how does it affect signal integrity?
The VESD03A2-03GHG3-08 has a typical capacitance of 112 pF at 0 V and 1 MHz. This value is optimized for interfaces up to 480 Mbps (e.g., USB 2.0 full-speed), where it introduces minimal rise-time degradation while providing effective ESD suppression-verified in HDMI DDC and UART applications.
How is the pin configuration arranged in the SOT-323 package of VESD03A2-03GHG3-08?
The VESD03A2-03GHG3-08 uses a standard SOT-323 pinout: pin 1 is Anode 1, pin 2 is Anode 2, and pin 3 is the common Cathode. This configuration supports independent protection of two signal lines with shared ground return, minimizing PCB routing complexity and inductance.
Can VESD03A2-03GHG3-08 be used for bidirectional signal lines like I²C?
Yes, VESD03A2-03GHG3-08 can protect bidirectional lines such as I²C SDA/SCL when configured with anode-to-signal and cathode-to-ground. Its unidirectional architecture relies on the pull-up resistor to bias the line above VRWM during normal operation, enabling effective clamping during negative ESD transients.
