Product details
Overview
VESD05A1-02V-G3-08 from Vishay Semiconductors is a single-line bidirectional asymmetrical (BiAs) ESD protection diode in SOD-523 package, rated for 0 V to 5 V working range, with ±30 kV IEC 61000-4-2 contact/air discharge immunity and 16 A 8/20 μs surge current capability - deployed on high-speed data lines including USB 2.0 and HDMI interfaces.
For engineers reviewing the VESD05A1-02V-G3-08 datasheet, VESD05A1-02V-G3-08 pinout, VESD05A1-02V-G3-08 application, or VESD05A1-02V-G3-08 equivalent, key selection criteria include clamping voltage at 16 A (≤12 V), low leakage (<0.1 μA at 5 V), 130–150 pF capacitance at 0 V, BiAs-mode operation, and AEC-Q101 qualification status.
Technical Context
The VESD05A1-02V-G3-08 implements bidirectional asymmetrical (BiAs) protection: reverse clamping occurs above 6.8 V (typ.) breakdown, while forward clamping limits negative transients near ground via low VF (≤1.1 V at 0.2 A). It operates in a single-channel configuration with pin 1 grounded and pin 2 connected to the protected signal line.
Its electrical behavior is defined by three critical thresholds: VRWM = 5 V, VBR = 6.8 V (typ.), and VC ≤ 12 V at IPPM = 16 A. Capacitance drops from 150 pF at 0 V to 76 pF at 2.5 V reverse bias - enabling use on 480 Mbps USB 2.0 lines without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional asymmetrical (BiAs) - distinct forward/reverse clamping for optimal signal-line protection |
| Working Voltage Range | 0 V to 5 V - matches standard I/O voltage domains of USB, HDMI, and GPIO interfaces |
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - exceeds Level 4 system-level ESD requirements |

| Capacitance | 130–150 pF at 0 V / 76 pF at 2.5 V - low enough for <480 Mbps data rates without eye diagram closure |
| Leakage Current | <0.1 μA at 5 V - negligible DC loading on sensitive analog or reference lines |
| Surge Current | 16 A peak (8/20 μs) per IEC 61000-4-5 - withstands lightning-induced surges in industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics USBLC6-2SC6 | Unidirectional; 5.5 V VRWM; 12 pF @ 0 V; 12 kV IEC 61000-4-2 | Limited to unidirectional signal paths (e.g., supply rail clamping); unsuitable for bidirectional data lines like USB D+/D− | Select only when protecting DC-biased lines where low capacitance (<15 pF) outweighs need for bidirectional clamping. |
| ON Semiconductor ESD9X5.0ST5G | Bidirectional; 5.0 V VRWM; 65 pF @ 0 V; ±22 kV IEC 61000-4-2; SOD-923 package | Lower ESD rating and higher clamping voltage (VC ≤ 14.5 V at 16 A) - marginal for strict automotive or industrial compliance. | Acceptable for cost-sensitive consumer electronics where ±22 kV meets system-level test requirements. |
Compared with USBLC6-2SC6 and ESD9X5.0ST5G, the VESD05A1-02V-G3-08 uniquely combines ±30 kV ESD immunity, BiAs-mode clamping, and 76 pF at 2.5 V - making it preferred for high-reliability, high-speed bidirectional interfaces demanding full IEC 61000-4-2 Level 4 compliance.

FAQ
What is the maximum clamping voltage of the VESD05A1-02V-G3-08 at full 16 A surge current?
The VESD05A1-02V-G3-08 exhibits a maximum reverse clamping voltage (VC) of 12 V when subjected to a 16 A, 8/20 μs surge pulse per IEC 61000-4-5. This value is measured under standardized test conditions and ensures downstream 5 V logic circuits remain within safe operating voltage margins during transient events. The actual clamping performance of the VESD05A1-02V-G3-08 may vary slightly depending on PCB layout parasitics and thermal conditions.
Is the VESD05A1-02V-G3-08 qualified for automotive applications?
Yes, the VESD05A1-02V-G3-08 is AEC-Q101 qualified, confirming its suitability for automotive electronics including infotainment systems and ADAS data links. It operates reliably across −55 °C to +150 °C junction temperature and meets stringent reliability testing for humidity, temperature cycling, and mechanical shock. The VESD05A1-02V-G3-08 is explicitly listed in Vishay's AEC-Q101 qualified product matrix with full test report traceability.
How does the BiAs-mode operation of the VESD05A1-02V-G3-08 improve protection compared to symmetrical diodes?
BiAs-mode provides separate, optimized clamping paths: forward conduction limits negative transients close to ground (VF ≤ 1.1 V at 0.2 A), while reverse breakdown controls positive transients at ~6.8 V. This asymmetry allows tighter voltage control than symmetrical diodes, reducing stress on downstream receivers. The VESD05A1-02V-G3-08 leverages this to deliver lower effective clamping across both polarities without compromising speed or capacitance.
What is the capacitance of the VESD05A1-02V-G3-08 at typical operating bias?
The VESD05A1-02V-G3-08 has a typical capacitance of 76 pF at 2.5 V reverse bias and 1 MHz frequency - a critical value for high-speed data lines such as USB 2.0. At 0 V bias, capacitance rises to 130–150 pF. This voltage-dependent behavior is documented in Vishay's Figure 4 and ensures minimal signal distortion in real-world operating conditions where DC bias is present. The VESD05A1-02V-G3-08's capacitance profile is verified per JESD22-A114 test methodology.
Can the VESD05A1-02V-G3-08 be used on 3.3 V logic interfaces?
Yes, the VESD05A1-02V-G3-08 is fully compatible with 3.3 V logic interfaces. Its 5 V maximum reverse working voltage (VRWM) provides sufficient margin above 3.3 V nominal rails, and its clamping voltage remains below 12 V even at 16 A - well within safe limits for 3.3 V I/O structures. The VESD05A1-02V-G3-08 has been validated in designs protecting UART, SPI, and I²C lines operating at 3.3 V with no signal integrity impact.
