1.4KESD5.0 thru 1.4KESD170CA AXIAL-LEAD TVS
SCOTTSDALE DIVISION
DESCRIPTION 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.

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-35 Package. Also available in surface mount DO-213AA MELF package (see separate data sheet)
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) * Flexible axial-lead mounting terminals * 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 curve in Figures #1 and 2. * Operating and storage temperature -65oC to 175oC * THERMAL RESISTANCE: Less than 250oC/W junction to lead at 0.375 inches from body. * DC power dissipation 500 mW at TL = 75oC at 3/8 inch (10 mm) lead length from body. * Derate at 2.3 W/oC above 25oC for PPP (1s) and at o o 5 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 axial-lead glass DO-35 (DO-204AH) package * TERMINALS: Leads, tin-lead plated solderable per MIL-STD-750, method 2026 * POLARITY: Banded end is cathode * WEIGHT: 0.2 grams (typical) * MARKING: Part number * TAPE & REEL option: Standard per EIA-296 (add "TR" suffix to part number) * See package dimension on last page
