Application note
IEC 61000-4-2 standard testing
Introduction
This Application note is addressed to technical engineers and designers to explain how
STMicroelectronics protection devices are tested according to IEC 61000-4-2 standard.
This standard, describing testing and measurements techniques for electrostatic discharge
immunity, is dedicated to electrical and electronic equipment, and the way to apply it to
standalone electronics components may not be obvious.
Market environment
The IEC 61000-4-2 standard is commonly used to certify equipment such as mobile phones,
computers and any sensitive electronic equipment. Each of these devices has to be
protected against electrostatic discharges using components able to clamp and resist the
high voltages generated and defined by each standard level. The robustness of these
devices has to be checked and guaranteed.
Frequently asked questions
This document provides responses to the following:
1. Contact discharge or air discharge method?
2. What about the IEC 61000-4-2 test bench?
3. How do we test ESD in air discharge?
4. How do we test ESD in contact discharge?
5. How do we measure the clamping voltage?
