DESCRIPTION
APPEARANCE
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.

FEATURES APPLICATIONS / BENEFITS
Protects Sensitive circuits from short duration fast
rise time transients such as Electrostatic Discharge
(ESD) or Electrical Fast Transients (EFT)
Minimal capacitance (See Figure #3)
Small surface-mount footprint for high density
mounting
Bidirectional features available by adding a “C” or
“CA” suffix to part number
Excellent protection in clamping direct ESD level
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
Working Stand-off Voltage range of 5V to 170V
Hermetic DO-213AB package. Also available in
axial-leaded DO-41package (see separate data
sheet for 14KESD5.0 series)
MAXIMUM RATINGS
4000 Watts for One Microsecond Square Wave or
14,000 watts per ESD Wave form of MIL-STD-750,
method 1020.
