14KESD5.0 thru 14KESD170CA, 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.

* For bidirectional, add a “C” or “CA” suffix after the part number, e.g. 14KESD5.0C or 14KESD5.0CA for the
14KESD5.0 or 14KESD5.0A part numbers respectively. Capacitance will be one-half that shown in Figure 3 for zero volts.
