AXIAL-LEAD TVS
S C O T T S D A L E D I V I S I O N
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.
DO-35
(DO-204AH)
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)
•
•
Protects Sensitive circuits from short duration fast
rise time transients such as Electrostatic Discharge
(ESD) or Electrical Fast Transients (EFT)

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.
Low inherent capacitance for high-frequency
applications (See Figure #4)
