14KESD5.0 thru 14KESD170CA

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.
