1 / 4 page AXIAL-LEAD TVS SCOTTSD A L E DIVISION 14KESD5.0 thru 14KESD170CA DESCRIPTION APPEARANCE 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. DO-41 (DO-204AL) IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • 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-41 Package. Also available in surface mount DO-213AB MELF package (see separate data sheet) • 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) • Flexible axial-lead mounting terminals • Bidirectional features available by adding a “C” or “CA” suffix MAXIMUM RATINGS MECHANICAL AND PACKAGING • 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 –65 oC to 175oC • THERMAL RESISTANCE: Less than 83 oC/Watt junction to lead at 0.375 inches from body. • DC power dissipation 1500 mW at TL = 75 oC at 3/8 inch (10 mm) lead length from body. • Derate at 22.8 W/ oC above 25oC for PPP (1µs) and at 15 mW/ oC above 75oC for dc power. • Forward Surge Current 500 amps for 1 µs at TL = 25 oC (rise time > 100 ns). • CASE: Hermetically sealed axial-lead glass DO-41 (DO-204AL) package • TERMINALS: Leads, tin-lead plated solderable per MIL-STD-750, method 2026 • POLARITY: Banded end is cathode • WEIGHT: 0.378 grams (typical) • MARKING: Part number • TAPE & REEL option: Standard per EIA-296 (add “TR” suffix to part number) • See package dimension on last page Microsemi Scottsdale Division 8700 E.
