The Yageo P2300SD is a Thyristor Surge Protection Device (TSPD) that is used to protect circuits from voltage and current spikes over a wide range of applications. This device is packaged in a DO214AA package, which can handle 190V and up to 200A of current. The P2300SD has a fast response time and low operating temperature, which helps to reduce the risk of damage to electronic circuits caused by electrical surges. It also features a built-in visual indicator so that users can quickly see when the device is activated and needs replacing. The P2300SD is an ideal choice for overvoltage protection in a wide range of applications.
