DESCRIPTION
APPEARANCE
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-204AL)

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-41 Package. Also available in surface
mount DO-213AB MELF package (see separate
data sheet)
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
