They have a long lifetime compared with diodes, and the varistor failure mode is a short circuit. This prevents damage to the load that may result if failure of the protection circuit is undetected.

The varistor granular structure does not allow ... Low-voltage signal paths are offered better protection from TVS diodes; however, some loads may operate within their SOA with either device.

Circuit protection devices, including transient voltage suppression (TVS) diodes and varistors ... Examples include ultra small surface-mount multi-layer varistor (MLV) devices for protecting small ...

New Enhanced Varistor Protection (EVP) arresters are now available superseding the Ohio Brass (OB) PVN family of arresters. New Enhanced Varistor Protection (EVP) arresters are now available ...

and silicon avalanche suppression diodes (SASDs). Damage from transient overvoltages is one of the leading causes of equipment failure. Although some pieces of equipment may come equipped with ...

New Enhanced Varistor Protection (EVP) arresters are now available, superseding the Ohio Brass PVN family of arresters. New Enhanced Varistor Protection (EVP) arresters are now available, superseding ...

The AOZ1390DI offers an Ideal Diode True Reverse Current Blocking (IDTRCB) protection, which prevents the undesired reverse current from VOUT to VIN. Furthermore, the integrated back-to-back MOSFE ...

It’s for this reason, robust system designs implement an ideal diode approach. Typically, such solutions were implemented discretely and require many external components and lack protection ...
