AXIAL-LEAD TVS

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-41 (DO-204AL)

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

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
