Description
Fixed Voltage Series DO-214 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.
Features and Benefits
t Low voltage overshoot t Low on-state voltage t Does not degrade with
use
t Fails short circuit when surged in excess of ratings
t Integrated diode for positive voltage surges
