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. 1.4KESD5.0C or 1.4KESD5.0CA for the

1.4KESD5.0 or 1.4KESD5.0A part numbers respectively. Capacitance will be one-half that shown in Figure 4 at zero volts.

** At 400 watts 1µs square wave rating (See Figures 1 and 2).
