| MLL1.4KESD5.0 thru MLL1.4KESD170CA SURFACE MOUNT TVS SCOTTSDALE DIVISION 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 WWW . Microsemi .C OM DO-213AA IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com 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 "C" or "CA" suffix MAXIMUM RATINGS * 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 -65oC to 175oC * THERMAL RESISTANCE: 150oC/W junction to end cap * DC power dissipation 500 mW at TEC 100oC * Derate at 2.3 W/oC above 25oC for PPP (1s) and at o o 6.67 mW/ C above 100 C for dc power * Forward Surge Current 50 amps for 1s at TL = 25oC (rise time > 100 ns) MECHANICAL AND PACKAGING * CASE: Hermetically sealed glass DO-213AA surface mount package * TERMINALS: Leads, tin-lead plated solderable per MIL-STD-750, method 2026 * POLARITY: Banded end is cathode * WEIGHT: 0.04 grams (typical) * MARKING: Cathode band only * TAPE & REEL option: Standard per EIA-481-B (add "TR" suffix to part number) * See package dimension on last page 1.4KESD5.0 - 1.4KESD170A Copyright 2003 10-06-2003 REV A Microsemi Scottsdale Division 8700 E.
