AXIAL-LEAD TVS
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.
APPEARANCE
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
DO-41
(DO-204AL)
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)
RoHS Compliant devices available by adding “e3” suffix
APPLICATIONS / BENEFITS
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)
Flexible axial-lead mounting terminals
Bidirectional features available by adding a “C” or
“CA” suffix
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.
DC power dissipation 1500 mW at TL = 75oC at 3/8
inch (10 mm) lead length from body.
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).
MECHANICAL AND PACKAGING
CASE: Hermetically sealed axial-lead glass DO-41
(DO-204AL) package
FINISH: Tin-lead or RoHS compliant matte-Tin
plating solderable per MIL-STD-750, method 2026
POLARITY: Banded end is cathode
WEIGHT: 0.378 grams (typical)
MARKING: Part number
TAPE & REEL option: Standard per EIA-296 (add
“TR” suffix to part number)
