DESCRIPTION
APPEARANCE
These small axial-leaded 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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

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-35 Package. Also available in surface
mount DO-213AA MELF package (see separate data
sheet)
RoHS Compliant devices available by adding “e3” suffix
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)
Flexible axial-lead mounting terminals
Bidirectional features available by adding a “C” or
“CA” suffix
