Product details
Overview
VESD03A1C-02Z-GS08 from Vishay Semiconductors is a bidirectional asymmetrical (BiAs) ESD protection diode in SOD923 package, designed for single-line signal/data line protection. It delivers ±30 kV IEC 61000-4-2 contact/air discharge immunity, 46 pF capacitance at 2.5 V, <0.5 µA leakage at 3.3 V, and clamps transients to ≤10 V at 9.5 A peak pulse current - ideal for USB 2.0, HDMI, and high-speed serial interface protection.
For engineers reviewing the VESD03A1C-02Z-GS08 datasheet, VESD03A1C-02Z-GS08 pinout, VESD03A1C-02Z-GS08 application, or VESD03A1C-02Z-GS08 equivalent, key selection criteria include bidirectional asymmetrical clamping behavior, ultra-low profile (0.4 mm height), sub-10 V clamping at 9.5 A, 78–85 pF capacitance at 0 V, and MSL Level 1 solderability.
Technical Context
The VESD03A1C-02Z-GS08 operates in BiAs mode: reverse clamping initiates above 5–6.6 V breakdown (VBR), while forward clamping limits negative transients near ground via low VF (≤2.5 V at 9.5 A). Its protection path is strictly between pin 1 (ground) and pin 2 (signal line), with no internal series impedance beyond intrinsic device resistance.
It meets IEC 61000-4-5 surge immunity (95 W, 9.5 A, 8/20 µs) and IEC 61000-4-2 ESD immunity (±30 kV), with junction temperature range of –40 °C to +125 °C and storage up to +150 °C. The SOD923 footprint requires 0.37 mm pad width and 0.9 mm center-to-center spacing per Vishay's recommended layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - ensures robustness against human-body model events in handheld and portable interfaces |
| Clamping Voltage | ≤10 V at 9.5 A (IEC 61000-4-5) - limits transient voltage seen by downstream ICs during surge events |
| Capacitance | 46 pF at VR = 2.5 V, 1 MHz - preserves signal integrity on 480 Mbps USB 2.0 lines without excessive rise-time degradation |
| Leakage Current | <0.5 µA at VR = 3.3 V - minimizes standby power loss and avoids false triggering in low-voltage logic rails |
| Reverse Standoff | 3.3 V (VRWM) - matches standard 3.3 V I/O supply rails, enabling direct placement before transceivers |
| Package Height | 0.4 mm max - enables use in ultra-thin mobile designs where board clearance is constrained |
| Moisture Sensitivity | MSL Level 1 (J-STD-020) - allows unlimited floor life and reflow without baking preconditioning |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to system ground; serves as return path for both positive and negative ESD currents |
| Pin 2 | Anode | Connected to protected signal/data line; conducts negative transients forward and positive transients in reverse breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical Clamping (BiAs) | Enables tighter negative clamping (~0.9–2.5 V) and controlled positive clamping (6.4–10 V), reducing stress on grounded-side circuitry |
| Ultra-Low Capacitance Variation | Capacitance drops from 85 pF (0 V) to 46 pF (2.5 V), minimizing distortion on bias-sensitive high-speed lines |
| SOD923 Footprint Compatibility | Standardized 0.9 mm × 0.75 mm outline with 0.37 mm pad width - supports automated placement and reflow in high-volume mobile PCB assembly |
| Lead (Pb)-Free & RoHS Compliant | Fully compliant with RoHS 2002/95/EC and WEEE 2002/96/EC - meets global environmental compliance requirements without derating |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in smartphone, tablet, and peripheral USB ports against ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Signal-line transient suppressor placed immediately before USB transceiver IC input pins. Use Value: 46 pF capacitance avoids violating USB 2.0 rise-time spec (≤2 ns), while ±30 kV immunity prevents latch-up or damage during handling. |
Use Scenario: Shielding individual TMDS clock and data channels in compact HDMI connectors on monitors, set-top boxes, and gaming consoles. IC Role / Device Role / Timing Role: Per-channel ESD clamp mounted adjacent to HDMI receptacle, before equalizer or retimer ICs. Use Value: Sub-10 V clamping at 9.5 A ensures HDMI sink ICs remain within absolute maximum ratings during hot-plug ESD events. |
| Mobile Display Serial Interfaces | Industrial Sensor Data Lines |
Use Scenario: Safeguarding MIPI D-PHY or eDP lanes in OLED/LCD display modules integrated into wearables and medical handhelds. IC Role / Device Role / Timing Role: Point-of-entry protection on flexible printed circuit (FPC) connectors linking display driver to host SoC. Use Value: 0.4 mm height enables integration beneath tight bezel assemblies; MSL Level 1 simplifies manufacturing flow. |
Use Scenario: Hardening RS-485, CAN FD, or I²C signal lines in factory-floor sensors exposed to static-prone environments. IC Role / Device Role / Timing Role: Localized ESD suppression at sensor node connector, upstream of isolated transceiver or level shifter. Use Value: Bidirectional asymmetry accommodates both positive and negative transients common in industrial grounding noise scenarios. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9B3.3ST5G | Unidirectional; 3.3 V VRWM; 15 pF @ 0 V; 12 V clamping @ 1 A | Limited to positive-only transients; lower capacitance suits >1 Gbps interfaces but lacks negative clamping | Select when protecting only positively biased lines (e.g., 3.3 V GPIO) and ultra-low capacitance is critical |
| TPD2E001DRYR | Bidirectional; 5 V VRWM; 11 pF @ 0 V; 12 V clamping @ 1 A; integrated 50 Ω series resistor | Higher standoff voltage and added series impedance alter signal integrity; not suitable for 3.3 V rail-constrained layouts | Prefer for 5 V systems with margin for higher clamping; avoid where 3.3 V VRWM alignment or minimal parasitics are required |
Compared with ESD9B3.3ST5G and TPD2E001DRYR, the VESD03A1C-02Z-GS08 uniquely balances 3.3 V compatibility, ±30 kV immunity, and asymmetrical clamping - making it optimal for space-constrained 3.3 V high-speed interfaces where both polarity transients must be suppressed without adding series resistance.

FAQ
What is the maximum operating temperature range for the VESD03A1C-02Z-GS08?
The VESD03A1C-02Z-GS08 has a junction temperature range of –40 °C to +125 °C and a storage temperature range of –55 °C to +150 °C. These ratings ensure reliable operation in automotive infotainment displays, industrial HMI panels, and outdoor-connected devices where ambient thermal extremes occur. The VESD03A1C-02Z-GS08 maintains specified clamping performance across this full range when properly mounted on thermally adequate PCB copper.
Does the VESD03A1C-02Z-GS08 support IEC 61000-4-5 surge testing?
Yes, the VESD03A1C-02Z-GS08 is rated for 95 W peak pulse power and 9.5 A peak pulse current under IEC 61000-4-5 (8/20 µs waveform), with clamping voltage ≤10 V at that current level. This makes the VESD03A1C-02Z-GS08 suitable for secondary-level surge protection in consumer and industrial interfaces where lightning-induced surges may couple onto data lines.
How does the BiAs mode of the VESD03A1C-02Z-GS08 improve protection compared to standard bidirectional diodes?
The VESD03A1C-02Z-GS08's BiAs mode provides asymmetric clamping: negative transients clamp near ground (VF ≈ 0.9–2.5 V), while positive transients clamp at 6.4–10 V (VC). This reduces stress on grounded-side circuitry and avoids forward-biasing downstream components during negative ESD events - a benefit not delivered by symmetric bidirectional diodes like the PESD5V0S1BA.
Is the VESD03A1C-02Z-GS08 compatible with lead-free reflow processes?
Yes, the VESD03A1C-02Z-GS08 is qualified for lead-free soldering at 260 °C for 10 seconds at terminals and carries MSL Level 1 rating per J-STD-020. Its SOD923 package and RoHS-compliant construction allow direct integration into standard Pb-free reflow profiles without pre-baking or special handling - critical for high-throughput mobile PCB assembly.
What is the typical capacitance of the VESD03A1C-02Z-GS08 at zero bias, and why does it matter?
The VESD03A1C-02Z-GS08 exhibits 78–85 pF capacitance at VR = 0 V and 1 MHz. This value directly impacts high-speed signal integrity: excessive capacitance degrades edge rates and causes reflections. The VESD03A1C-02Z-GS08's 46 pF at 2.5 V bias better reflects real-world operating conditions on 3.3 V lines, ensuring accurate timing margin analysis for USB 2.0 and similar protocols.
