MLL1.4KESD5.0 thru MLL1.4KESD170CA, e3
SURFACE MOUNT TVS
SCOTTSDALE DIVISION
DESCRIPTION
These small surface mount 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. MLL1.4KESD5.0C or MLL1.4KESD5.0CA for MLL1.4KESD5.0 or
MLL1.4KESD5.0A 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).
