SURFACE MOUNT TVS

SCOTTSD A L E DIVISION

MLL14KESD5.0 thru MLL14KESD170A

DESCRIPTION

APPEARANCE

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

APPLICATIONS / BENEFITS

• 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 data

sheet for 14KESD5.0 series)

• Protects Sensitive circuits from short duration fast

rise time transients such as Electrostatic Discharge

(ESD) or Electrical Fast Transients (EFT)

• Minimal capacitance (See Figure #3)

• Small surface-mount footprint for high density

mounting

• Bidirectional features available by adding a “C” or

“CA” suffix to part number

MAXIMUM RATINGS
