The P8S33CA with 53.3V 36.7V 33V - TVS ROHS is a Surge Protection Device (SPD) manufactured by Leiditech. This electronic part is designed to protect against dangerous electrical surges by limiting the amount of current that passes through a system. It is available in a variety of voltage ratings, ranging from 33V to 53.3V, with UL, VDE, EN/IEC, and RoHS certifications. It is also designed to provide a low-impedance path to ground when activated, giving it the advantage of higher surge current capabilities than other models, and giving it superior protection in the event of a surge. The P8S33CA can also be directly mounted onto printed circuit boards or used in conjunction with other surge protection components, making it a cost-effective solution for both residential and commercial applications.
