Bourns TISP61089BDRS Telecom Overvoltage Protector

The TISP61089B is a dual forward-conducting buffered P-gate thyristor (SCR) overvoltage protector designed for telecommunication circuits. It provides reliable overvoltage and lightning protection for Subscriber Line Interface Circuits (SLICs) by clipping positive voltages to ground and switching into a low-impedance on-state during negative overvoltage events. The device tracks the negative supply voltage, minimizing stress on the circuitry. Its high reliability, high holding current, and compatibility with Bellcore and ITU-T standards make it ideal for protecting sensitive telecom equipment against transient surges and power faults.
