The P0640SC-MS is a SMB Thyristor Surge Suppressor (TSS) manufactured by MSKSEMI. This device uses a network of thyristors and resistors to suppress transient voltages that occur frequently on power and signal lines, providing a high level of surge protection against overvoltage, short circuit, and hazardous overcurrent conditions. The P0640SC-MS is RoHS (Restriction of Hazardous Substances Directive) compliant and lead-free, meeting the requirements for a broad range of industrial applications. It is available in SMB through-hole packages with maximum steady state power rating up to 960W and peak pulse power rating up to 1800W. Additionally, it can operate in temperatures ranging from -55°C to +175°C, making it suitable for harsh environments.
