ESD Protection

STMicroelectronics

Protection against electrostatic discharges (ESD) is part of EMC Immunity (Electro Magnetic Compatibility) requirements. It is the ability for equipment to properly operate in its electromagnetic environment by limiting the reception of electromagnetic energy that may cause physical damage. ESD can be either conducted under the form of a transient voltage or can be radiated due to its fast rising time: powerful harmonics will generate erratic behavior by the application by coupling with other signals. Printed circuit boards must be protected against the effects of electrostatic discharge.
