SCOTTSDALE DIVISION
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.
IMPORTANT: For the most current data, consult
• 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)
FEATURES
• 400 Watts for One Microsecond Square Wave or 1400 watts per ESD Wave form of MIL-STD-750, method 1020
• See Surge Rating curves in Figures #1, 2 and 3
• Operating and storage temperature –65
• THERMAL RESISTANCE: 150
cap
• DC power dissipation 500 mW at T
• Derate at 2.3 W/
6.67 mW/
• Forward Surge Current 50 amps for 1µs at T (rise time >
