These devices feature the ability to clamp dangerous high voltage short term transients such as produced by directed or radiated electro-static-discharge phenomena before entering sensitive component regions of a circuit design. They are small economical transient voltage suppressors targeted primarily for short term transients below a few microseconds while still achieving significant peak-pulse-power capability as seen in Figure #1.
