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.
Description
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 Replaces four discrete
devices
t Two-port protection
t LCAS specific tip and
ring thresholds

Notes:
- Absolute maximum ratings measured at T
A
= 25ºC (unless otherwise noted).
- Devices are bi-directional.
- All electrical characteristics shown are defined from Tip 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).
