一.产品概述
This device is especially designed to protect Subscriber Line Interface Circuit (SLIC) against transient overvoltage. Positive overloads are clipped with 2 diodes. Negative surges are suppressed by 2 Thyristors, their breakdown voltage being referenced to VBAT through the gate. This component presents a very low gate triggering current and minimizes overvoltage stress on the SLIC
二.产品特点
Dual programmable transient suppressor
Wide battery voltage supports
Low gate triggering current
High holding current.
ESD Immunity(HBM): JESD22 Class 3B, ≥8KV
MLS: Lever 1 – unlimited
三.应用范围
Switch Line Card
Access Network Line Card
PBX
VoIP
