Description
Fixed
Voltage Q2L Series are uni-directional SIDACtor® devices designed to protect SLICs (Subscriber Line Interface Circuit) from damaging over
voltage 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.
Features and Benefits
t Integrated diode for positive
voltage surges
t Low profile t Small footprint QFN
Package
t Low on-state
voltage
t Does not degrade with use
t Fails short circuit when surged in excess of ratings
Applicable Global Standards
