  • Page 17: Appendix A - Esd Testing Background

    Appendix A - ESD Testing Background The rapid advancement in the electronics industry during the past two decades has placed increasing importance on the understanding of electrostatics and its effect on electronic devices and systems. Electrostatic discharge (ESD) is a common cause of microelectronic circuit failure. Many devices can be seriously damaged or destroyed by an electrostatic discharge below 20 Volts.
  • Page 18 This circuit is specified in Mil-Std-883H, Method 3015.8 and ANSI/ESDA/JEDEC JS-001-2010 (formally ANSI/ESD-STM 5.1 and JEDEC TEST METHOD A114.A) to represent a human body discharge for ESD testing. The human body capacitance may be as high as several hundred picofarads, but more typically, ranges between 60 to 500pF. Studies have shown that approximately 80% of the population that was tested has a capacitance of 100pF or less.
