MLL14KESD5.0 thru MLL14KESD170A
SURFACE MOUNT TVS
SCOTTSDALE DIVISION
DESCRIPTION
These surface mount Transient Voltage Suppressor (TVS) devices feature
the ability to clamp dangerous high voltage short-term transients such as
produced by direct or radiated electro-static discharge phenomena before
entering sensitive component regions of a circuit design. They are small
economical TVSs targeted primarily for short term transients below a few
microseconds while still achieving significant peak-pulse-power capability
as seen in Figure 1.

transients in excess of 40,000 V per MIL-STD-750,
Method 1020 (approx. 150 ns exponential wave)
•
Absorbs ESD level transients of 14,000 Watts per
MIL-STD-750, Method 1020 (approximately 150 ns
exponential wave, or one microsecond transients
up to 4000 watts. See Figure #1 and #2 for overall
transient Peak Pulse Power.
•
Clamps Transients in less than 100 picoseconds

* For bidirectional, add a “C” or “CA” suffix after the part number, e.g. MLL14KESD5.0C or MLL14KESD5.0CA for the
MLL14KESD5.0 or MLL14KESD5.0A part numbers respectively. Capacitance will be one-half that shown in Figure 3 for zero volts.
** At 4000 watts 1µs square wave rating (See Figures 1 and 2).
