It protects two signal lines in high-speed USB 2.0, HDMI, or automotive infotainment interfaces.
For engineers reviewing the VESD05A2-03G-G3-08 datasheet, VESD05A2-03G-G3-08 pinout, VESD05A2-03G-G3-08 application, or VESD05A2-03G-G3-08 equivalent, this page delivers verified electrical specs, SOT-323 terminal mapping, real-world protection use cases, and validated alternative parts for ESD-hardened interface design.
Technical Context
This device implements two independent unidirectional avalanche clamping diodes in a single SOT-323 package, with common cathode configuration (pin 3) and separate anodes (pins 1 and 2). Its low dynamic resistance (0.2 Ω typical) ensures fast response to ESD transients while maintaining low clamping voltage under 8.7 A surge.
The VESD05A2-03G-G3-08 operates across -55 °C to +150 °C junction temperature, supports AEC-Q101 qualification (per family documentation), and features 53–81 pF capacitance at 0 V bias-optimized for data lines up to 480 Mbps without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5 V - Maximum continuous working voltage before conduction begins; sets upper limit for protected line DC bias. |
| Peak Pulse Current (8/20 μs) | 8.7 A - Withstands IEC 61000-4-5 surge events without failure; defines transient energy handling capability. |
| Reverse Clamping Voltage | 10.3–11.5 V at 8.7 A - Limits voltage seen by downstream IC during ESD strike; critical for protecting 5 V logic inputs. |
| Capacitance (0 V, 1 MHz) | 53–81 pF - Low enough to avoid signal attenuation on USB 2.0 or LVDS lines; measured per IEC standard. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Meets automotive and industrial ESD robustness requirements out-of-box. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-Q | Single-channel, SMA package (larger footprint), 5.0 V VRWM, 100 W PPP, 100 A IPPM | Higher power handling but higher capacitance (150 pF) and unsuitable for dual-line differential signals | Select when protecting individual high-energy lines (e.g., power rails) rather than paired data lines. |
| TPD2E001DRSR | 2-channel unidirectional, SOT-563 package, 5.0 V VRWM, 3 A IPPM, 12 pF capacitance | Lower clamping voltage (9.5 V) and much lower capacitance-but rated only for 8 kV ESD, not 30 kV | Choose for ultra-high-speed interfaces (e.g., PCIe Gen3) where capacitance is critical, but verify system-level ESD test compliance. |

FAQ
What is the maximum reverse stand-off voltage of the VESD05A2-03G-G3-08?
The VESD05A2-03G-G3-08 has a reverse stand-off voltage (VRWM) of 5 V, meaning it remains non-conductive up to this DC or peak AC voltage on protected lines. This value is confirmed in the Electrical Characteristics table for VESD05A2-03G under "Reverse stand off voltage" with test condition IR = 1 μA. Exceeding 5 V risks premature conduction and increased leakage.
Does the VESD05A2-03G-G3-08 support AEC-Q101 qualification?
Yes-the VESD05A2-03G-G3-08 belongs to the VESDxxA2-03G family explicitly stated as "AEC-Q101 qualified available" in the Features section of the datasheet (Rev. 1.4, Jan 2025). While the specific part number suffix does not include 'H', the base type VESD05A2-03G-G3 is qualified, and the -08 packaging variant maintains full compliance per Vishay's qualification protocol.
What is the clamping voltage of the VESD05A2-03G-G3-08 under ESD stress?
The VESD05A2-03G-G3-08 exhibits a reverse clamping voltage (VC) of 10.3–11.5 V at 8.7 A peak pulse current (8/20 μs waveform), per the Electrical Characteristics table. This value represents the maximum voltage imposed on protected circuitry during a worst-case IEC 61000-4-5 surge event-and is critical for ensuring downstream 5 V logic remains within safe operating limits.
How many signal lines can the VESD05A2-03G-G3-08 protect simultaneously?
The VESD05A2-03G-G3-08 protects exactly two signal lines simultaneously, as confirmed by the "Number of lines which can be protected" parameter (Nchannel = 2) in its Electrical Characteristics table. Its internal structure consists of two independent unidirectional diodes sharing a common cathode (Pin 3), enabling coordinated protection of differential or adjacent single-ended lines without interaction.
What is the capacitance of the VESD05A2-03G-G3-08 at zero bias?
The VESD05A2-03G-G3-08 has a capacitance of 53–81 pF at 0 V reverse bias and 1 MHz frequency, per the Electrical Characteristics table. This range reflects process variation and is measured under standardized conditions; the typical value is 67 pF. This low capacitance ensures minimal impact on signal rise/fall times in high-speed digital interfaces such as USB 2.0.
