Product details
Overview
VESD01-02V-G-08 from Vishay Semiconductors is a single-line ESD-protection diode in SOD-523 package, designed for low-voltage signal line protection with 1 V reverse stand-off voltage, ±8 kV contact/±15 kV air ESD immunity per IEC 61000-4-2, and 9 V clamping voltage at peak pulse current. It serves in USB, HDMI, and audio interface circuits where ultra-low capacitance (180 pF) and minimal leakage (<100 µA at 1 V) are critical.
For engineers reviewing the VESD01-02V-G-08 datasheet, VESD01-02V-G-08 pinout, VESD01-02V-G-08 application, or VESD01-02V-G-08 equivalent, this device is selected for sub-1-V logic-level signal lines requiring fast transient response, low clamping voltage, and compatibility with high-speed digital interfaces without signal integrity degradation.
Technical Context
The VESD01-02V-G-08 implements a unidirectional avalanche diode structure optimized for electrostatic discharge suppression on single-ended data lines. Its 1.5 V breakdown voltage at 1 mA and 9 V clamping voltage at 7 A (8/20 µs) define its protective threshold and voltage limiting behavior under surge conditions.
It operates across –40 °C to +125 °C junction temperature and complies with IEC 61000-4-5 (63 W peak pulse power) and IEC 61000-4-2 (±8 kV contact, ±15 kV air), with MSL level 1 moisture sensitivity and lead-free (e3 Sn) termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse stand-off voltage | 1 V - Maximum continuous working voltage before conduction begins; matches 1.0 V logic rails and low-voltage I/O domains. |
| Clamping voltage (at 7 A) | 9 V - Voltage seen by protected circuit during 8/20 µs surge; limits stress on downstream IC inputs. |
| Capacitance (0 V, 1 MHz) | 180 pF - Low enough for <100 Mbps signal lines but not suitable for >480 Mbps USB 2.0 or HDMI. |
| ESD immunity | ±8 kV contact / ±15 kV air - Meets IEC 61000-4-2 Level 4 for system-level ESD robustness. |
| Leakage current | ≤100 µA at 1 V - Ensures negligible DC loading on sensitive analog or low-power digital signals. |
| Package | SOD-523 - 1.3 mm × 0.85 mm footprint; compatible with fine-pitch automated placement and reflow (260 °C/10 s). |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode bar marking; dimensions 1.3 mm × 0.85 mm × 0.6 mm (L × W × H); weight 1.4 mg; UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Signal line input | Connected to protected trace; conducts during positive transients when cathode is biased higher. |
| Cathode | Ground reference | Connected to system ground or low-impedance return path; defines clamping reference and polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Single-line ESD protection | Dedicated protection for one signal path-no cross-talk or shared clamping impedance between lines. |
| e3 Sn termination | Lead-free, RoHS-compliant matte tin plating-ensures solderability and long-term intermetallic stability. |
| Low leakage current | ≤100 µA at VR = 1 V-preserves battery life and avoids false triggering in always-on sensor interfaces. |
| MSL level 1 rating | No floor life limitation-can be stored indefinitely before reflow without baking or dry pack requirements. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protection of D+ and D– lines in portable USB peripherals against user-handling ESD events. IC Role / Device Role: Unidirectional shunt clamp placed between signal line and ground. Use Value: Limits transient voltage to ≤9 V during ±8 kV contact discharge, preventing damage to USB transceiver ESD structures. |
Use Scenario: ESD safeguarding of HDMI Display Data Channel (DDC) clock and data lines in monitors and set-top boxes. IC Role / Device Role: Standoff-limited transient suppressor on 5 V-tolerant I²C-compatible bus lines. Use Value: 180 pF capacitance avoids timing skew on 100 kHz DDC signaling while maintaining ±15 kV air discharge immunity. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: Protection of microphone and headset detection lines in 3.5 mm TRRS jacks exposed to frequent plug insertion/removal. IC Role / Device Role: Low-capacitance, low-leakage clamp on bias-sensitive analog paths. Use Value: 100 µA max leakage preserves DC bias integrity; 1 V VRWM ensures compatibility with 1.2–1.8 V codec I/O levels. |
Use Scenario: Transient suppression on 4–20 mA loop-powered sensor outputs in factory automation panels. IC Role / Device Role: Secondary protection stage after primary TVS, handling residual fast-rising ESD pulses. Use Value: 9 V clamping prevents latch-up in precision op-amps; SOD-523 size enables dense layout near connector entry points. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9B1.0ST5G | Same SOD-523 package; 1.0 V VRWM; 12 V clamping at 4 A; 120 pF capacitance. | Higher clamping voltage reduces protection margin for 1.0 V logic; lower capacitance benefits faster edges. | Select when lower capacitance is prioritized over tighter clamping, e.g., in RF front-end bias lines. |
| Infineon ESD204-B1-02ELS | Bidirectional configuration; 2.5 V VRWM; 14 V clamping at 5 A; 15 pF capacitance. | Not suitable for unidirectional 1 V rails; requires redesign for symmetric transient handling. | Choose only if bidirectional protection and sub-20 pF capacitance are mandatory, such as in high-speed differential pairs. |
Compared with ESD9B1.0ST5G and ESD204-B1-02ELS, the VESD01-02V-G-08 delivers the lowest clamping voltage (9 V) among 1 V-rated SOD-523 diodes, making it optimal for ultra-low-voltage I/O protection where post-clamp voltage headroom is constrained.

FAQ
What is the maximum operating temperature range for the VESD01-02V-G-08?
The VESD01-02V-G-08 supports a junction temperature range of –40 °C to +125 °C, enabling use in automotive cabin modules, industrial controllers, and outdoor consumer devices where ambient thermal extremes are encountered. This rating is verified per JEDEC J-STD-020 and applies under specified power dissipation limits. The VESD01-02V-G-08 maintains its 1 V stand-off and 9 V clamping performance across this full range.
Is the VESD01-02V-G-08 unidirectional or bidirectional?
The VESD01-02V-G-08 is a unidirectional ESD protection diode, configured with anode and cathode terminals to clamp only positive transients relative to ground. Its electrical characteristics-including 1 V reverse stand-off voltage and 1.5 V breakdown at 1 mA-are defined for forward-biased conduction from cathode to anode. The VESD01-02V-G-08 is not rated for reverse transient suppression.
Does the VESD01-02V-G-08 meet RoHS and halogen-free requirements?
Yes, the VESD01-02V-G-08 carries e3 Sn (matte tin) termination and conforms to RoHS Directive 2011/65/EU and JEDEC JS709A halogen-free standards. Vishay certifies full compliance in its Material Category Policy documentation (doc. 99912), and the device carries no restricted substances above threshold limits. The VESD01-02V-G-08 is suitable for environmentally regulated markets including EU and China RoHS.
What is the moisture sensitivity level (MSL) of the VESD01-02V-G-08?
The VESD01-02V-G-08 is rated MSL level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry packing or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during 260 °C/10 s reflow profiles. The VESD01-02V-G-08's SOD-523 package uses UL 94 V-0 molding compound to further ensure process robustness.
Can the VESD01-02V-G-08 protect USB 3.0 or HDMI 2.0 signals?
No, the VESD01-02V-G-08 is not suitable for USB 3.0 SuperSpeed (5 Gbps) or HDMI 2.0 (18 Gbps) due to its 180 pF capacitance, which would severely attenuate high-frequency components and violate eye diagram mask requirements. It is validated only for USB 2.0 (480 Mbps), HDMI DDC (100 kHz), and other low-to-medium speed interfaces. For those applications, the VESD01-02V-G-08 remains effective and cost-optimized.
