1.4KESD5.0 thru 1.4KESD170CA, e3
AXIAL-LEAD TVS
SCOTTSDALE DIVISION
DESCRIPTION
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.
