SLIC Protection
Fixed Voltage Q2L Series are uni-directional SIDACtor
®
devices designed to protect SLICs (Subscriber Line Interface
Circuit) from damaging overvoltage transients.
The series provides single line protection using a fixed voltage
switching device for negative surges. All positive surges
are routed through an internal diode to a ground reference.
The small size of the Q2L makes it ideal for high density
applications.
