1.4KESD5.0 thru 1.4KESD170CA, e3 AXIAL-LEAD TVS SCOTTSDALE DIVISION APPEARANCE These small axial-leaded TVS devices feature the ability to clamp dangerous high voltage short-term transients such as produced by directed or radiated electrostatic 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 illustrated in Figure #1.
