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.
FEATURES
• 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)
APPLICATIONS / BENEFITS
• 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
