Transient voltages and electrostatic discharge (ESD) are typical problems that impact the reliability and durability of electronic equipment. Transient voltage suppression (TVS) diodes provide surge protection to protect internal electronics from damage.
Electronic devices and equipment function optimally within a specified maximum working voltage, above which latent or catastrophic failures may occur in internal components. An overvoltage condition occurs when the supply voltage in electronic equipment exceeds its absolute maximum rated voltage. It can result from several sources, including lightning strikes, electrostatic discharge, insulation failure, arcing, or switching electromagnetic pulses (SEMPs). Particularly for electronic devices, ESD events can occur in normal product use and also in the manufacturing process, and it is crucial to protect against ESD threats.
