ESD suppressors are electronic components designed to protect sensitive electronics from electrostatic discharge (ESD) events. These events can occur when two objects with different electric potentials come into contact with each other, causing a sudden flow of electric current. ESD events can damage or destroy electronic components, leading to costly repairs or replacements. ESD suppressors work by diverting the excess current away from the sensitive electronics, preventing damage. They are commonly used in a variety of applications, including consumer electronics, medical devices, and industrial equipment. With the increasing prevalence of electronics in our daily lives, ESD suppressors are becoming an essential component for protecting our devices and ensuring their longevity.

Frequently Asked Questions (FAQs)
1. Is ESD protection necessary?
Protecting against the effects of electrostatic discharge is an essential requirement for any manufacture, home construction, service, repair and any other area in contact with electronic boards and components.
2. What is ESD protection?
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.
3. What is the difference between ESD and TVS?
TVS diodes are particularly efficient in countering medium-voltage high-energy pulses that last milliseconds, in comparison to ESD protection devices which address higher voltage pulses of lower energy and shorter duration.
4. What is ESD clamping voltage?
The ESD clamping voltage is the voltage drop across the ESD protection diode during an ESD event per the IEC61000−4−2 waveform.
