Vishay Technology VESD03A1C-02Z, VESD05A1C-02Z, and VESD12A1C-02Z: Single-line ESD-protection diodes target space-limited applications

Aiming at portable electronics and other space-sensitive applications, the VESD03A1C-02Z, VESD05A1C-02Z, and VESD12A1C-02Z silicon, single-line, ESD (electrostatic-discharge)-protection zener diodes have 3.3, 5, and 12V reverse-working ranges. Within these working ranges, the diodes offer a high isolation-to-ground feature characterized by less-than-1-µA leakage current and less-than-85-pF capacitances. Providing a 0.6×1-mm footprint with a 0.4-mm profile, the diodes allow placement close to the interface connector or in front of the ESD-sensitive IC ports. The diodes clamp or short to ground any transient-voltage signal exceeding the reverse-breakthrough-voltage level. Negative-transient-voltage signals drive the diodes in the forward direction, clamping the transient close below the ground level. Available in an SOD923 package, the VESD03A1C-02Z, VESD05A1C-02Z, and VESD12A1C-02Z diodes cost $7 (1000) each.
