The Bourns TISP1072F3DR-S is a dual forward-conducting unidirectional thyristor overvoltage protector. It is designed for protecting ICs used in Subscriber Line Interface Circuits (SLIC) from overvoltage events such as lightning strikes and AC power surges.
This device limits voltages that exceed the supply rails. It operates by initially clamping negative transients through breakdown and then crowbarring when the voltage reaches the breakover level. Positive transients are handled by diode forward conduction. The protector is rated to suppress and withstand international lightning surge wave shapes.
Key electrical specifications include a breakdown voltage of 72V and a peak surge current of 8A for a 2/10 μs waveshape. The off-state current is less than 10 μA. The component features a capacitance of 0.5pF and is housed in a surface-mount 8-SOIC package.
This series is available but not recommended for new designs. Customers should verify actual device performance in their specific applications.
