MLL1300S

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).
