MLL1.4KESD5.0 thru MLL1.4KESD170CA SURFACE MOUNT TVS SCOTTSDALE DIVISION APPEARANCE 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. DO-213AA IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com 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.
