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.
