Thyristors Provide Enhanced Surge Protection

Description

SIDACtor protection thyristors are optimized to protect equipment located in high exposure environments from severe overvoltage transients. The Pxxx0MEL 5kA Series and Pxxx0FNL 3kA Series SIDACtor protection thyristors offer enhanced reliability through multiple high energy surge events. Unlike many non-semiconductor-based high power protective products, which can experience functional degradation after only a few surge events, the Pxxx0MEL and Pxxx0FNL Series are semiconductor-based components, and will continue to provide protection through multiple surge events without functional degradation.

 

Pxxx0MEL 5kA Series SIDACtor protection thyristors in TO-218 packaging are available in tube pack in quantities of 250, with 25 devices per tube and 10 tubes per box.

 

Pxxx0FNL 3kA Series SIDACtor protection thyristors in TO-262M packaging are available in tube pack in quantities of 500 (50 per tube) or in tray pack in quantities of 100.

Specs
