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.
