MLL1.4KESD5.0 thru MLL1.4KESD170CA
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.

MIL-STD-750, Method 1020 (approx. 150 ns
exponential wave, or one microsecond transients up
to 400 watts. See Figure #1 and #2 for overall
transient Peak Pulse Power.
•
Clamps Transients in less than 100 picoseconds
•
Working Stand-off Voltage range of 5 V to 170 V

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).
