Description
T10B Series are SIDACtor® devices designed protect
baseband equipment such as modems, line cards, CPE and
DSL from damaging overvoltage transients.
The series provides a robust and cost effective through-
hole solution that enables equipment to comply with global
regulatory standards
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 High Surge Current
