Product details
Overview
VESD08-02V-G-08 from Vishay Semiconductors is a single-line ESD protection diode in SOD-523 package, rated for 8 V reverse stand-off voltage, ±8 kV contact / ±15 kV air ESD immunity per IEC 61000-4-2, 30 V clamping voltage at peak pulse current, and 35 pF capacitance at 0 V bias - deployed in USB 2.0 data lines and low-speed serial interfaces.
For engineers reviewing the VESD08-02V-G-08 datasheet, VESD08-02V-G-08 pinout, VESD08-02V-G-08 application, or VESD08-02V-G-08 equivalent, key selection criteria include reverse stand-off voltage matching interface logic levels, clamping voltage margin relative to IC absolute maximum ratings, leakage current (<0.1 µA at 8 V), capacitance impact on signal integrity, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
The VESD08-02V-G-08 implements a unidirectional silicon avalanche diode structure optimized for transient suppression on single-ended I/O lines. Its 8 V VRWM aligns with 5 V–8 V logic families, while 30 V VC ensures safe clamping below typical 3.3 V/5 V interface IC breakdown thresholds.
With 35 pF capacitance at 0 V and <0.1 µA IR at VR = 8 V, it balances ESD robustness and signal fidelity for DC-coupled, low-frequency digital paths. The device operates from –40 °C to +125 °C junction temperature and meets MSL level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse stand-off voltage (VRWM) | 8 V - maximum continuous DC operating voltage before conduction begins; matches 5 V–8 V interface rails. |
| Clamping voltage (VC) | 30 V at IPP - peak voltage seen by protected IC during 4 A 8/20 μs surge; provides margin below 33 V abs max ratings. |
| Capacitance (CD) | 35 pF at 0 V, 1 MHz - limits bandwidth degradation on signals up to ~100 MHz; suitable for USB 2.0 and UART. |
| ESD immunity | ±8 kV contact / ±15 kV air per IEC 61000-4-2 - exceeds industrial and consumer end-equipment immunity requirements. |
| Leakage current (IR) | ≤0.1 µA at 8 V - negligible loading on high-impedance or battery-powered signal lines. |
| Peak pulse power (PPP) | 120 W per IEC 61000-4-5 - handles short-duration surges without thermal failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Bi-directional, 5.5 V VRWM, 12 V VC, 12 pF capacitance | Better suited for bidirectional AC-coupled lines (e.g., HDMI, SD card); lower capacitance but lower VRWM | Select when protecting symmetric differential pairs or sub-5 V logic where tighter clamping is critical. |
| ESD9B5.0ST5G | Unidirectional, 5.0 V VRWM, 14.5 V VC, 30 pF capacitance | Lower VRWM limits use to 3.3 V systems; higher clamping margin than VESD08-02V-G-08 at same current | Prefer for 3.3 V microcontroller GPIOs where 8 V VRWM would cause unnecessary leakage or misclamping. |
Compared with TPD2E001DRYR and ESD9B5.0ST5G, the VESD08-02V-G-08 offers higher VRWM for 5 V–8 V interfaces and higher clamping voltage tolerance, making it optimal for legacy industrial serial links and USB 2.0 where signal swing exceeds 5 V and ESD threat level is ≥±8 kV contact.

FAQ
What is the maximum continuous operating voltage for VESD08-02V-G-08?
The VESD08-02V-G-08 has a reverse stand-off voltage (VRWM) of 8 V, meaning it can continuously block up to 8 V DC without entering conduction. This makes it suitable for protecting interfaces operating at nominal 5 V or 8 V logic levels, such as certain industrial serial buses and legacy USB implementations. Exceeding 8 V risks premature leakage or clamping during normal operation.
Does VESD08-02V-G-08 meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, the VESD08-02V-G-08 is rated for ±8 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2, satisfying Level 4 - the highest severity class defined in the standard. This rating is validated over 10 pulses and applies to the device itself; system-level compliance also depends on PCB layout, grounding, and proximity to protected ICs.
What is the clamping voltage of VESD08-02V-G-08 under a 4 A ESD surge?
The VESD08-02V-G-08 exhibits a maximum clamping voltage (VC) of 30 V when subjected to its rated peak pulse current of 4 A (8/20 μs waveform). This value represents the peak voltage imposed on the protected line during an ESD event and must be compared against the absolute maximum input voltage rating of the downstream IC to ensure survivability.
Can VESD08-02V-G-08 be used on bidirectional signal lines like I²C?
No - the VESD08-02V-G-08 is a unidirectional diode, designed only for DC-biased or single-polarity signal paths. Using it on bidirectional lines such as I²C may result in unintended conduction during negative half-cycles. For I²C or other bidirectional interfaces, a bi-directional ESD protector like TPD2E001DRYR is required instead of VESD08-02V-G-08.
Is VESD08-02V-G-08 RoHS-compliant and halogen-free?
Yes, the VESD08-02V-G-08 carries e3 matte tin terminations and conforms to RoHS Directive 2011/65/EU. It also meets JEDEC JS709A halogen-free requirements, with bromine and chlorine content below 900 ppm each and total halogens under 1500 ppm - verified per Vishay's Material Category Policy documentation.
