Product details
Overview
VESD03-02V-G-08 from Vishay Semiconductors is a single-line ESD protection diode in SOD-523 package, rated for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2, with 3 V reverse stand-off voltage, 12 V clamping voltage at peak pulse current, and 110 pF capacitance at 0 V bias - deployed on high-speed USB 2.0 data lines to suppress transient overvoltage.
For engineers reviewing the VESD03-02V-G-08 datasheet, VESD03-02V-G-08 pinout, VESD03-02V-G-08 application, or VESD03-02V-G-08 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant ESD immunity levels, and real-world interface protection use cases without generic claims or unsupported performance assertions.
Technical Context
The VESD03-02V-G-08 implements a unidirectional TVS structure optimized for low-capacitance signal line protection. Its 3 V reverse stand-off voltage and 4 V breakdown threshold enable safe operation on 3.3 V logic interfaces while maintaining fast response to sub-nanosecond ESD transients.
With 9 A peak pulse current handling (8/20 μs waveform) and 108 W peak pulse power rating, it sustains robust protection under IEC 61000-4-5 surge conditions without thermal runaway, supported by MSL level 1 moisture sensitivity and UL 94 V-0 flammability compliance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.9 pF typical capacitance; 5 V stand-off; bidirectional configuration | Better suited for high-speed USB 3.0 or MIPI lanes where sub-1 pF is mandatory | Select when <1 pF capacitance is required and 5 V operating margin is acceptable |
| ESD9X3.3SCT5G | 3.3 V stand-off; 15 V clamping; 100 pF capacitance; same SOD-523 package | Nearly identical electrical profile but higher clamping voltage increases risk to sensitive 3.3 V receivers | Acceptable for cost-sensitive designs where 15 V clamping is tolerable and supply chain diversification is needed |
Compared with TPD2E001DRYR and ESD9X3.3SCT5G, the VESD03-02V-G-08 offers the optimal balance of 3 V stand-off compatibility with 3.3 V systems, 12 V clamping headroom, and 110 pF bandwidth-making it preferred for USB 2.0 and I²C where moderate capacitance is acceptable and precise voltage matching is critical.

FAQ
What is the maximum operating temperature range for the VESD03-02V-G-08?
The VESD03-02V-G-08 has a junction temperature range of -40 °C to +125 °C and a storage temperature range of -55 °C to +150 °C. This allows deployment in extended-temperature environments such as automotive cabin modules and industrial controllers where ambient heat buildup occurs. The VESD03-02V-G-08 maintains specified clamping and leakage behavior across this full range when properly mounted on thermally adequate PCB copper.
Does the VESD03-02V-G-08 support lead-free reflow soldering?
Yes, the VESD03-02V-G-08 features e3 matte tin (Sn) terminations and is qualified for lead-free reflow per J-STD-020, with a maximum peak temperature of 260 °C for 10 seconds at the terminals. Its SOD-523 package and UL 94 V-0 molding compound withstand standard Pb-free thermal profiles without delamination or solder joint reliability issues. The VESD03-02V-G-08 is fully compliant with RoHS Directive 2011/65/EU.
How does the VESD03-02V-G-08 differ from the VESD05-02V-G-08 in practical design use?
The VESD03-02V-G-08 has a 3 V reverse stand-off voltage and 12 V clamping voltage, making it ideal for 3.3 V I/O domains, whereas the VESD05-02V-G-08 uses a 5 V stand-off and 20 V clamping - better suited for 5 V logic or mixed-voltage systems. Using VESD05-02V-G-08 on a 3.3 V line risks false triggering; the VESD03-02V-G-08 ensures tighter voltage margin alignment without sacrificing ESD robustness.
Is the VESD03-02V-G-08 unidirectional or bidirectional?
The VESD03-02V-G-08 is a unidirectional ESD protection diode, configured with anode and cathode terminals and designed for DC-biased signal lines like USB D+ and D−. Its electrical characteristics - including reverse stand-off voltage and breakdown threshold - are specified for forward/reverse polarity relative to ground. It is not rated for bidirectional AC-coupled applications unless externally biased.
What is the moisture sensitivity level (MSL) rating for the VESD03-02V-G-08?
The VESD03-02V-G-08 carries an MSL level 1 rating per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60 % RH and requires no dry-pack or baking prior to assembly. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during reflow. The VESD03-02V-G-08's SOD-523 package and UL 94 V-0 epoxy contribute to this robust MSL classification.
