How ESD Protection Diodes Safeguard Sensitive Electronics?

ESD protection diodes work as bidirectional devices, meaning they effectively protect electronic components against both positive and negative voltage spikes caused by ESD events. These diodes are constructed using advanced semiconductor materials, allowing them to respond quickly to high-voltage transients.

During an ESD event, when a significant voltage spike occurs, the ESD protection diode instantly activates, providing a low-resistance path to divert the excessive energy away from the sensitive component. By promptly diverting the energy away, the diode limits the voltage applied to the vulnerable electronic device, thus preventing any potential harm.
