A current limiter plays a crucial role in ESD protection by restricting the flow of electric current during an electrostatic discharge event. When a sudden surge of static electricity occurs, it can potentially damage sensitive electronic components. The primary function of the current limiter is to mitigate this risk by limiting the amount of current that can pass through to the components, thereby protecting them from excessive current that could cause overheating or failure.

By maintaining this restriction, the current limiter helps ensure that any potentially harmful surges are managed in a way that reduces the likelihood of damage to the electronic devices involved. This is especially important in environments where static discharge can occur frequently, such as in electronics manufacturing, testing facilities, or other areas where sensitive equipment is handled. The effectiveness of a current limiter in this protective role is vital in preserving the integrity and longevity of electronic systems.
