SURFACE MOUNT TVS
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.

APPEARANCE
DO-213AA
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 âCâ or
âCAâ suffix
