Product details
Overview
VESD05A1-02V-G-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 such as USB 2.0 or HDMI interfaces.
For engineers reviewing the VESD05A1-02V-G-08 datasheet, VESD05A1-02V-G-08 pinout, VESD05A1-02V-G-08 application, or VESD05A1-02V-G-08 equivalent, key selection criteria include clamping voltage at 16 A (≤12 V), low leakage (<0.1 μA at 5 V), 130 pF capacitance at 0 V, BiAs-mode operation, and AEC-Q101 qualification status.
Technical Context
The VESD05A1-02V-G-08 implements bidirectional asymmetrical clamping: reverse breakdown occurs at 6–7.5 V (VBR), clamping to ≤12 V at 16 A IPPM; forward conduction limits negative transients to ≤4.5 V at 16 A. Its BiAs architecture enables tighter ground-referenced clamping for negative events versus standard bidirectional devices.
Designed for signal integrity-critical interfaces, it delivers 76 pF capacitance at 2.5 V reverse bias and maintains MSL level 1 handling per J-STD-020 with peak reflow tolerance up to 260 °C - supporting automated optical inspection (AOI) via e3 Sn-plated lead frame sidewalls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact & air discharge per IEC 61000-4-2 - ensures robust system-level ESD immunity without external shielding. |
| Clamping Voltage (16 A) | ≤12 V reverse / ≤4.5 V forward - limits transient overvoltage to safe levels for 5 V logic and USB PHYs. |
| Capacitance (0 V) | 130–150 pF - compatible with USB 2.0 (≤15 pF typical) only when used with series impedance or in low-speed lines. |
| Leakage Current | <0.1 μA at 5 V VR - prevents signal degradation and battery drain in always-on portable interfaces. |
| Surge Current | 16 A (8/20 μs) per IEC 61000-4-5 - withstands lightning-induced surges in automotive and industrial edge nodes. |
| Package | SOD-523 (1.3 × 0.85 × 0.7 mm) - enables ultra-compact placement adjacent to connectors with minimal PCB area. |
| Operating Temp | −55 °C to +150 °C - supports under-hood automotive and industrial control unit deployments. |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode marking bar; footprint requires 0.9 mm pad length, 0.7 mm pad width, and 0.75 mm center-to-center spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (ground connection) | Connected directly to system ground plane to provide low-inductance return path for ESD current. |
| Pin 2 | Anode (signal line connection) | Placed in series with protected data line (e.g., USB D+); conducts transient energy to ground during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-mode clamping | Asymmetric forward/reverse clamping enables sub-1 V negative transient suppression while maintaining 6–7.5 V reverse standoff - critical for ground-referenced signal integrity. |
| e3 Sn-plated lead frame | Tin plating on exposed side walls allows AOI-based solder joint verification without X-ray - reducing final test cost in high-volume consumer production. |
| AEC-Q101 qualification | Validated for automotive applications including infotainment and body electronics - meets stress testing for temperature cycling, HTRB, and ESD. |
| Low profile height | <0.7 mm max height - enables co-placement with thin connectors (e.g., micro-USB, FPC) in space-constrained mobile and wearable designs. |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60 % RH - eliminates bake requirements and simplifies SMT line logistics for contract manufacturers. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-handling ESD events. IC Role / Device Role / Timing Role: Standalone ESD suppressor placed immediately before USB connector, operating in BiAs mode to clamp both polarities.

Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in factory automation I/O modules from field ESD. IC Role / Device Role / Timing Role: High-isolation (VRWM = 5 V) shunt device on 0–5 V output lines, minimizing loading on precision amplifiers. Use Value: Delivers <0.1 μA leakage and 76 pF capacitance at 2.5 V bias - preserving DC accuracy and bandwidth of 20 kHz sensor signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR (Texas Instruments) | Lower capacitance (11 pF @ 0 V), unidirectional, 12 V clamping at 16 A, SOT-5X3 package (larger than SOD-523). | Better suited for high-speed USB 2.0 where capacitance must be <15 pF; not AEC-Q101 qualified. | Select when signal integrity dominates over space constraints and automotive qualification is unnecessary. |
| ESD5Z5.0T1G (ON Semiconductor) | Similar SOD-523 footprint, bidirectional, 5.0 V VRWM, but higher leakage (≤1 μA) and no AEC-Q101 certification. | Cost-optimized alternative for consumer-grade USB ports where automotive reliability is not required. | Choose for non-automotive applications needing identical board layout but lower BOM cost. |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, the VESD05A1-02V-G-08 uniquely combines AEC-Q101 qualification, BiAs-mode clamping, and SOD-523 size - making it the only option among the three validated for automotive infotainment signal lines requiring both compactness and high-temp reliability.

FAQ
What is the maximum clamping voltage of the VESD05A1-02V-G-08 at 16 A surge current?
The VESD05A1-02V-G-08 exhibits a reverse clamping voltage (VC) of ≤12 V and a forward clamping voltage (VF) of ≤4.5 V when subjected to a 16 A 8/20 μs pulse per IEC 61000-4-5. These values are measured under standardized test conditions and define the upper voltage limit imposed on protected lines during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The VESD05A1-02V-G-08 achieves this performance while maintaining its SOD-523 form factor.
Is the VESD05A1-02V-G-08 qualified for automotive applications?
Yes, the VESD05A1-02V-G-08 is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness per automotive reliability standards. This qualification confirms suitability for use in automotive infotainment, body electronics, and ADAS sensor interfaces where extended temperature operation (−55 °C to +150 °C) and long-term reliability are mandatory. The VESD05A1-02V-G-08 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
How does the BiAs-mode operation of the VESD05A1-02V-G-08 improve ESD protection?
BiAs-mode (bidirectional asymmetrical) operation enables the VESD05A1-02V-G-08 to clamp positive transients at 6–7.5 V breakdown and negative transients near ground (≤4.5 V at 16 A) due to forward conduction. This asymmetry provides tighter voltage control for negative events - crucial for protecting ground-referenced signals like USB D+ without compromising reverse standoff. Unlike symmetrical diodes, the VESD05A1-02V-G-08 avoids excessive forward voltage overshoot, preserving signal integrity in mixed-polarity environments.
What is the capacitance of the VESD05A1-02V-G-08 at 2.5 V reverse bias?
At 2.5 V reverse bias and 1 MHz frequency, the VESD05A1-02V-G-08 exhibits a typical capacitance of 76 pF, with no maximum specified. This reduced capacitance versus the 130–150 pF value at 0 V improves high-frequency signal fidelity on data lines such as HDMI HPD or low-speed UART. Designers should reference the capacitance vs. voltage curve (Fig. 4 in the datasheet) to model loading effects accurately - especially important when placing the VESD05A1-02V-G-08 in parallel with fast-switching nodes.
Can the VESD05A1-02V-G-08 be used in USB 2.0 applications despite its 130 pF capacitance?
The VESD05A1-02V-G-08's 130–150 pF capacitance at 0 V exceeds typical USB 2.0 full-speed (<480 Mbps) recommendations of ≤15 pF, limiting direct use on high-speed D+/D− pairs. However, it is suitable for USB 2.0 upstream ports, ID pins, VBUS detection, or low-speed lines where bandwidth is not constrained. For full-speed data lines, designers may combine the VESD05A1-02V-G-08 with series impedance or select it for cost-sensitive, space-constrained applications where moderate signal degradation is acceptable - always validating eye diagram compliance per USB-IF test plans.
