DESCRIPTION
APPEARANCE
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.

FEATURES
APPLICATIONS / BENEFITS
Excellent protection in clamping direct ESD level
transients in excess of 15,000 V per MIL-STD-750,
Method 1020 (approx. 150 ns exponential wave)
Absorbs ESD level transients* of 1400 Watts per
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
Hermetic DO-213AA Package. Also available in
axial-leaded DO-35 package (see separate data
sheet for 1.4KESD5.0 series)
Protects Sensitive circuits from short duration fast
rise time transients such as Electrostatic Discharge
(ESD) or Electrical Fast Transients (EFT)
Low inherent capacitance for high-frequency
applications (See Figure #4)
Small surface mount foot print
Bidirectional features available by adding a “C” or
“CA” suffix
