The Asymmetrical Discrete Series are SIDACtor
®
devices
designed to protect LCAS (Line Circuit Access Switch)
devices from damaging overvoltage transients.
The series provides a specialized asymmetrical
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 LCAS specific tip and
ring thresholds
Applicable Global Standards
t TIA-968-A
t TIA-968-B
t ITU K.20/21 Enhanced
Level*
t ITU K.20/21 Basic Level
t GR 1089 Inter-building*
t GR 1089 Intra-building
t IEC 61000-4-5
t YD/T 1082
t YD/T 993
t YD/T 950
*A/B-rated parts require series resistance
Notes:
- Absolute maximum ratings measured at T
A
= 25ºC (unless otherwise noted).
- Devices are bi-directional.
