Littelfuse SIDACtor + MOV AC Line Protection

Littelfuse SIDACtor + MOV AC Line Protection offers an innovative method of using a silicon crowbar component known as the SIDACtor Protection Thyristor component for the main overvoltage protection solutions for AC power lines. SIDACtor Crowbar Protection features high surge current capability, low on-state voltage conditions, and lower overshoot during high dv/dt events. Littelfuse SIDACtor + MOV AC Line Protection is ideal for outdoor LED lighting, outdoor AC drives, and CATV Trunk amplifier network systems.

Features

High surge current capability
Low on-state voltage condition thus low thermal accumulation during long-term events
Lower overshoot during high dv/dt events
No wear-out mechanism
Multiple stand-off value choices that are closer to different country AC power line values without sacrificing over-shoot characteristics

MOV is low cost but with high clamping voltage and will wear out
Superior performance AK TVS diode is not cheap compared to MOV solution
SIDACtor component: semiconductor crowbar is the compromised solution in between TVS and MOV for AC main lightning protection
