ACTP250J1BJ Overview
The Bourns^® Model ACTP250J1BJ is a bidirectional thyristor designed to be used in series with an overvoltage clamp device, such as an MOV,
to protect a power supply from damage due to an overvoltage condition on its ac input lines. This device raises the turn-on voltage threshold of
the series combination against low frequency overvoltage conditions while having minimal impact on the voltage clamp level when subjected to
a lightning surge. Using this series combination will prevent the MOV from conducting when line frequency voltage swells (up to the sum of the
breakdown voltages of the two components) occur on the ac input lines of the power supply. This allows a design to avoid the use of a higher
voltage MOV, which, if used, would significantly reduce the level of lightning protection. See the Application section for additional information.
