Adding components to provide circuit protection against internal and external mishaps is one of those thankless design jobs, similar to buying insurance. When it’s not needed, it seems like an added ...

Several types of devices are employed in electronic systems to protect against voltage transients, power surges, and excessive voltage or current. Varistors is one of those devices that protect ...

Design engineers often give circuit protection only cursory attention. For example, fuses, diodes, and varistors are so well known that designers select them with ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...
