高压振铃SLIC保护器为短回路系统设计两个用户线接口电路的独立跟踪过电压保护CXPR7875QS正过电压通过该器件反平行二极管的正向传导被限制为公共过电压

CXPR7875QS该装置是专为短回路系统设计的。它可以作为两个用户线接口电路的独立跟踪过电压保护。正过电压通过该器件反平行二极管的正向传导被限制为公共过电压。负过电压最初是通过这种缓冲晶体管的发射极跟随器作用在SLIC负电源附近被截断的

一.产品概述

---

      This device is especially designed for short loop system. It can be Independent tracking overvoltage protection for two SLICs (Subscriber Line Interface Circuit). Positive overvoltages are clipped to common by forward conduction of this device antiparallel diode. Negative overvoltages are initially clipped close to the SLIC negative supply by emitter follower action of this buffer transistor.
