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.
