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.

Notes:
- Absolute maximum ratings measured at TA= 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).
