Description
Fixed Voltage Series Modified DO-214 are unidirectional SIDACtor® devices designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients.
The series provides single port protection using fixed voltage switching devices for negative surges. All positive surges are routed through internal diodes to a ground reference.
Features and Benefits
t Low voltage overshoot t Integrated diodes for
t Low on-state voltage
positive voltage surges
t Does not degrade with use t Single-port protection
t Fails short circuit when surged in excess of ratings
