Abstract: An electrostatic discharge is an event where humans can generate up to 1000V. These voltages, we ourselves generate, may not be a potential threat to people because of its short duration; but it is to any electronic circuit. A 1000V of ESD (Electro Static Discharge) event can destroy electronic circuits as these are never expected to operate at 1000V. Thus, the core of the electronic circuits needs a protector circuit. This seminar unravels the complexity of the protector circuit and gives detailed description on what is ESD? How do they look like? How does a device behave under ESD stress? What kind of protector circuit is used? How do they protect our cellphones, computers, TVs and game consoles? How do they protect our electronics in a lab/testing environment or in production (assembly lines)?
