This overvoltage protection or crowbar protection circuit is used where we need protection against high voltage surge. The circuit has a few components, it is very easy to build and will protect your ...

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 ...

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

POWER OVER ETHERNET (POE) enabled devices and their electronic components are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or ...

A variety of over-current and overvoltage products are on the market for protecting VDSL telecommunications circuits. These include transformer line-side capacitors, transformer driver-side diodes, ...
