The P0640S3NLRP-A from Littelfuse is an Automotive-Qualified Sidac that is designed to protect AC power lines located in hostile environments from over-voltage transients. It has a break-over voltage of up to 58 V and a break-over current of less than 250 A. This sidac provides robust surge protection with a high surge rating and ensures compliance with regulatory and customer surge requirements. It is suited for safeguarding exposed RS-485 interfaces and AC/DC power supplies. This AEC-Q101-qualified device boasts low voltage overshoot and low on-state voltage, enhancing its efficiency in protecting sensitive electronics. It is designed to fail and short circuit when surges beyond its ratings, which provides a clear indication of a fault. This sidac maintains its properties even after multiple surge handling cycles and provides fast response time in the order of microseconds. It is a RoHS-compliant sidac and is available in a surface-mount package that measures 8.130 x 6.220 mm.
