VESD05A1B-02V is a single-line ESD-protection device from vishay company. It has an ESD immunity of over 20 kV contact discharge and 30 kV air discharge. Its typical capacitance is 12 pF and leakage current is less than 0.1 µa. It is a lead-free, non-magnetic, RoHS and WEEE compliant product.
The VESD05A1B-02V ESD‑protection diode is designed for single‑line signal or data‑line protection. It operates in a bi‑directional asymmetrical (BiAs) mode, clamping positive transients by becoming conductive and shorting the surge to ground, while negative transients are clamped by the low forward voltage of the diode.
Key features include IEC 61000‑4‑2 compliance (>20 kV contact, >30 kV air discharge), typical capacitance of 12 pF, leakage current <0.1 µA, lead‑free and RoHS‑compliant packaging (SOD523), and a wide operating temperature range from –40 °C to +125 °C. This manual is written in Chinese.
