LCAS Protection  
Asymmetrical Multiport Series - MS-013  
Description  
Asymmetrical Multiport Series are SIDACtor® devices  
designed to protect LCAS (Line Circuit Access Switch)  
devices from damaging overvoltage transients.  
The series provides a specialized asymmetrical dual port  
overvoltage protection solution that enables equipment  
to comply with various global requlatory standards.  
Features and Benefits  
tꢀ Low voltage overshoot  
tꢀ Low on-state voltage  
tꢀ Replaces four discrete  
devices  
tꢀ Two-port protection  
tꢀ Does not degrade with  
Agency Approvals  
tꢀ LCAS specific tip and  
use  
ring thresholds  
tꢀ Fails short circuit when  
surged in excess of  
ratings

Notes:  
- Absolute maximum ratings measured atTA= 25ºC (unless otherwise noted).  
- Devices are bi-directional.  
- All electrical characteristics shown are defined fromTip to Ground (pin 1 to pin 2 and pin 6  
to pin 5) and Ring to Ground (pin 3 to pin 2 and pin 4 to pin 5).  
- XX = Part Number Suffix: ‘TP’ (Tube Pack) or ‘RP’ (Reel Pack).
