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). M Excellent Protection in Clamping Direct ESD Level Transients* in Excess of 15,000 Volts. . Absorbs ESD Level Transients* of 1400 Watts or One Microsecond Transients** up to 400 Watts. See Figure #1 For Overall Transient Peak Pulse Power. w 4. Clamps Transients in 1 Pico Second. SCOTTSDALE, AZ For more information call: (602) 947-6300 5. 0.5 Watt Continuous Power Dissipation. 6. Working (Stand-off) Voltage Range of 5V to 170V. 7. Hermetic DO-35 Package. Also Available in Surface Mount DO-213AA (MELF). 8. Low Inherent Capacitance for High Frequency Application (See Figure #4). 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.
