ESDsensitive

ESDsensitive, short for Electrostatic Discharge sensitive, refers to electronic components, assemblies, or equipment that can be damaged by a discharge of static electricity. Discharges can occur when a charged person or object comes into contact with or near a sensitive device, causing instantaneous electrical overstress or latent damage affecting performance or reliability. Common ESDS items include integrated circuits, memory devices, diodes, connectors, and sensors.

Damage can be catastrophic, causing immediate failure, or latent, reducing reliability over time. The risk depends on device architecture and the discharge model, such as human body model (HBM) or charged device model (CDM). Damage thresholds vary widely; some devices may fail at a few tens of volts, while others tolerate kilovolts before showing effects.

Protection and handling: ESDS items should be kept in grounded environments and transported in anti-static packaging. Use grounded wrist straps, ESD mats, and conductive flooring. Maintain humidity control to reduce static buildup and use ionizers when necessary. Avoid insulating materials like regular plastic bags and ensure proper grounding of tools and benches.

Labeling and standards: ESDS items are typically labeled with the ESDS symbol or the designation ESDS. Industry standards such as IEC 61340-5-1 and ANSI/ESD S20.20 specify programs for ESD control, including training, testing, and facility requirements. Best practice includes using static shield bags, anti-static foam, and properly rated grounding for personnel and equipment.
