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.

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)
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

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).
