SIDACtor® ProtectionThyristors
High Surge Current Protection
SIDACtor® Primary Protection Balanced Series - Modified TO-220
Description
The SIDACtor® Primary Protection Balanced Series
ModifiedTO-220 are thyristor devices designed for use in
primary protection applications.
The series provides a single port overvoltage solution
that enables applications to comply with the balance
requirements of GR-974 and GTS-8700. Please contact
Littelfuse to discuss your particular application and
regulatory requirements.
