What is an ESD Diode?

An ESD Diode is a specialized semiconductor component designed to shield electronic circuits from high-voltage surges. These diodes are engineered to handle rapid voltage changes, ensuring the safety of sensitive electronic components. They act as a safeguard against electrostatic discharge (ESD) that can arise from various sources, such as human touch or environmental factors.

The Development History of ESD Diodes

The evolution of ESD Diodes traces back to the early days of semiconductor technology. Initially, simple diodes and zener diodes were employed for ESD protection. As electronic devices grew more sophisticated, the demand for more advanced protection solutions led to the development of dedicated **ESD Diodes**. Innovations in material science and design have significantly enhanced their performance and reliability over the years.

Early Solutions
