DESCRIPTION

These surface mount Transient Voltage Suppressor (TVS) devices feature the ability to clamp dangerous high voltage short-term transients such as produced by direct or radiated electro-static discharge phenomena before entering sensitive component regions of a circuit design. They are small economical TVSs targeted primarily for short term transients below a few microseconds while still achieving significant peak-pulse-power capability as seen 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-213AB package. Also available in axial-leaded DO-41package (see separate

datasheet for 14KESD5.0 series)

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: 40 oC/W junction to end cap, or 120oC/W junction to ambient when mounted on FR4 PC board (1 oz Cu) with recommended footprint (see last page)

? Steady-State Power: 1.50 watts at TEC < 115oC, or 1.25 watts at TA = 25oC when mounted on FR4 PC board and recommended footprint as described for thermal resistance (also see Figure 1)

? 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).
