It serves as a low-capacitance (12–18 pF) transient suppressor for high-speed interfaces including USB 2.0, HDMI, and automotive infotainment data lines.
For engineers reviewing the VESD33C1-02V-G3-08 datasheet, VESD33C1-02V-G3-08 pinout, VESD33C1-02V-G3-08 application, or VESD33C1-02V-G3-08 equivalent, key selection criteria include its 33 V working voltage, ultra-low 15 pF typical capacitance at 0 V, 56–62.5 V clamping under 1.6 A surge, dynamic resistance of 3.6 Ω, and AEC-Q101 qualification readiness - critical for automotive and industrial interface protection where signal integrity and robustness are co-constrained.
Technical Context
The VESD33C1-02V-G3-08 implements a single-channel unidirectional TVS structure optimized for low-capacitance, high-voltage transient suppression. Its 33 V VRWM enables use on 24 V and 3.3 V logic-supplied lines with margin, while its 37.4 V typical breakdown (at 1 mA) ensures reliable triggering before system damage.
It delivers 15 kV IEC 61000-4-2 ESD protection with 56–62.5 V clamping at 1.6 A (8/20 μs), supported by 3.6 Ω dynamic resistance and <0.01 μA leakage at 33 V - enabling minimal signal distortion and low standby power impact in high-impedance data paths.
Key Specifications

The VESD33C1-02V-G3-08 has a junction temperature range of -55 °C to +150 °C and a storage temperature range of -55 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive modules, industrial motor drives, and outdoor smart infrastructure where ambient temperatures exceed 85 °C. The device maintains specified clamping and leakage performance across this full range.
Does the VESD33C1-02V-G3-08 meet AEC-Q101 qualification?
The VESD33C1-02V-G3-08 is AEC-Q101 qualified - confirmed in Vishay's official documentation for the VESDxxC1-02V family. This qualification covers stress tests including HTGB, AC-H3TRB, TC, and ESD, validating suitability for automotive applications such as infotainment, body electronics, and ADAS sensor interfaces where reliability is mission-critical.
What is the reverse leakage current of the VESD33C1-02V-G3-08 at rated standoff voltage?
At 33 V reverse voltage and 25 °C, the VESD33C1-02V-G3-08 exhibits a maximum reverse leakage current of 0.1 μA, with typical values below 0.01 μA. This ultra-low leakage ensures negligible loading on high-impedance sensor outputs, precision reference lines, and battery-powered IoT node inputs - preserving accuracy and extending operational lifetime.
