DESCRIPTION
APPEARANCE
These surface mount Transient Voltage Suppressor (TVS) devices feature
the ability to clamp dangerous high voltage short-term transients such as
produced by direct or radiated electro-static discharge phenomena before
entering sensitive component regions of a circuit design. They are small
economical TVSs targeted primarily for short term transients below a few
microseconds while still achieving significant peak-pulse-power capability
as seen in Figure 1.
