A+ Question of the Week: Electrostatic Discharge Damage

AplusQOW3How many volts of electrostatic discharge (ESD) are required to damage electronic components?

A. 3 volts
B. 30 volts
C. 300 volts
D. 3,000 volts

The correct answer is B.

It only takes 30V of ESD to damage low-voltage CMOS components. ESD cannot be felt by humans until approximately 300V. It cannot be seen by the naked eye in normal light until about 3,000V. By the time ESD can be detected, sensitive electronic circuitry can already be destroyed.
