Microsemi MLL1.4KESD15A Surface mount tv Datasheet

MLL1.4KESD5.0 thru MLL1.4KESD170CA
SURFACE MOUNT TVS
SCOTTSDALE DIVISION
APPEARANCE
These small surface mount 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.
DO-213AA
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
APPLICATIONS / BENEFITS
• Excellent protection in clamping direct ESD level
transients in excess of 15,000 V per MIL-STD-750,
Method 1020 (approx. 150 ns exponential wave)
• Absorbs ESD level transients* of 1400 Watts per
MIL-STD-750, Method 1020 (approx. 150 ns
exponential wave, or one microsecond transients up
to 400 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 5 V to 170 V
• Hermetic DO-213AA Package. Also available in
axial-leaded DO-35 package (see separate data
sheet for 1.4KESD5.0 series)
• Protects Sensitive circuits from short duration fast
rise time transients such as Electrostatic Discharge
(ESD) or Electrical Fast Transients (EFT)
• Low inherent capacitance for high-frequency
applications (See Figure #4)
• Small surface mount foot print
• Bidirectional features available by adding a “C” or
“CA” suffix
MAXIMUM RATINGS
MECHANICAL AND PACKAGING
• 400 Watts for One Microsecond Square Wave or
1400 watts per ESD Wave form of MIL-STD-750,
method 1020

• Derate at 2.3 W/oC above 25oC for PPP (1µs) and at
o
o
6.67 mW/ C above 100 C for dc power
• Forward Surge Current 50 amps for 1µs at TL = 25oC
(rise time > 100 ns)
• CASE: Hermetically sealed glass DO-213AA surface
mount package
• TERMINALS: Leads, tin-lead plated solderable per
MIL-STD-750, method 2026
• POLARITY: Banded end is cathode

• MARKING: Cathode band only
• TAPE & REEL option: Standard per EIA-481-B (add
“TR” suffix to part number)
• See package dimension on last page
