Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and reliability. Though often overshadowed by newer protection schemes, the crowbar ...

The circuit diagram shows the over voltage protection as a feature of LM317 linear voltage regulator. The circuit diagram shows the over voltage protection as a feature of LM317 linear voltage ...

Linear vs. switching surge stoppers. An input protection circuit featuring an LTC4380. Protection circuit design using a switching surge stopper. Reliable industrial electronics often have protection ...

Barring something like an incorrect transformer tap connection, an overvoltage is a momentary event in which voltage “surges” beyond nominal. We often call that a transient. A breaker or fuse is ...

Why a gas-discharge tube is an important component for overvoltage protection. The history of spark gaps—predecessors to GDTs—includes a role in famous movies. How a new, compact, surface-mount GDT ...
