Microsemi Corp. The diode experts SANTA ANA, CA Features . Protects Sensitive Circuits From Short Duration Fast Rise Time Transients such as Electro-Static-Discharge (ESD) or Electrical Fast Transients (EFT). N . Excellent Protection in Clamping Direct ESD Level Transients* in Excess of 40,000 Volts. w Absorbs ESD Level Transients* of 14,000 Watts or One Microsecond Transients** up to 4000 Watts. See Figure #1 For Overall Transient Peak Pulse Power. 4. Clamps Transients in 1 Pico Second. SCOTTSDALE, AZ For more information call: (602) 947-6300 5. 1.5 Watt Continuous Power Dissipation. 6. Working (Stand-off) Voltage Range of 5V to 170V. 7. Hermetic DO-41 Package. Also Available in Surface Mount DO-213AB (MELF). 8. Low Inherent Capacitance for High Frequency Application (See Figure #3 ). These devices feature the ability to clamp dangerous high voltage short term transients such as produced by directed or radiated electro- static-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 seen in Figure #1.
