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.

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-41 Package. Also available in surface mount DO-213AB MELF package (see separate data sheet)

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: Less than 83oC/Watt junction to lead at 0.375 inches from body.

? DC power dissipation 1500 mW at TL = 75oC 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 1μs at TL = 25oC (rise time > 100 ns).
