MLL14KESD5.0 thru MLL14KESD170A SURFACE MOUNT TVS
SCOTTSDALE DIVISION
DESCRIPTION These surface mount Transient Voltage Suppressor (TVS) devices feature the ability to clamp dangerous high voltage short-term transients such as produced by direct or radiated electro-static discharge phenomena before entering sensitive component regions of a circuit design. They are small economical TVSs targeted primarily for short term transients below a few microseconds while still achieving significant peak-pulse-power capability as seen in Figure 1.

DO-213AB
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 40,000 V per MIL-STD-750, Method 1020 (approx. 150 ns exponential wave) * Absorbs ESD level transients of 14,000 Watts per MIL-STD-750, Method 1020 (approximately 150 ns exponential wave, or one microsecond transients up to 4000 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 5V to 170V * Hermetic DO-213AB package. Also available in axial-leaded DO-41package (see separate data sheet for 14KESD5.0 series)
APPLICATIONS / BENEFITS
* Protects Sensitive circuits from short duration fast rise time transients such as Electrostatic Discharge (ESD) or Electrical Fast Transients (EFT) * Minimal capacitance (See Figure #3) * Small surface-mount footprint for high density mounting * Bidirectional features available by adding a "C" or "CA" suffix to part number
MAXIMUM RATINGS
* 4000 Watts for One Microsecond Square Wave or 14,000 watts per ESD Wave form of MIL-STD-750, method 1020. * See Surge Rating curve in Figures #1 and 2. * Operating and storage temperature -65oC to 175oC * Thermal Resistance: 40 C/W junction to end cap, or 120C/W junction to ambient when mounted on FR4 PC board (1 oz Cu) with recommended footprint (see last page) * Steady-State Power: 1.50 watts at TEC < 115oC, or 1.25 watts at TA = 25C when mounted on FR4 PC board and recommended footprint as described for thermal resistance (also see Figure 1) * Derate at 22.8 W/oC above 25oC for PPP (1s) and at 15 mW/oC above 75oC for dc power. * Forward Surge Current 500 amps for 1s at TL = o 25 C (rise time > 100 ns).
MECHANICAL AND PACKAGING
* CASE: Hermetically sealed DO-213AB glass MELF package * TERMINALS: End caps, tin-lead plated solderable per MIL-STD-750, method 2026 * POLARITY: Cathode indicated by band. * MARKING: Cathode band only * TAPE & REEL optional: Standard per EIA-481-B with 12 mm tape, 1500 per 7 inch reel or 5000 per 13 inch reel (add "TR" suffix to part number) * WEIGHT: 0.05 grams * See package dimensions on last page
