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).
