SPD is a surge protector, right!
SPD electrically denotes a surge protector
SPD: Surge Protection Device, a device used for protecting against surges. Overvoltage protection is provided for low-voltage equipment and circuits, primarily to prevent lightning intrusion waves.
SPD is the abbreviation for SERIAL PRESENCE DETECT, which in Chinese means serial detection of module presence.
It serves a protective purpose; I’m not exactly sure how it works, but there are types for lightning protection, for computers, and many others...

Why is it hidden now? The spirit of my forum, where everyone helps everyone, must not be trampled upon! ! ! Definition of SPD (Surge Protective Device): A Surge Protective Device (SPD), also known as a surge protector, lightning protector, or arrester, is used to protect electrical equipment from damage caused by lightning electromagnetic pulses or operational overvoltages. Introduction: 1. There are a vast array of types of surge protectors; in China’s market, there are already over a hundred different kinds of these devices. Determining how to classify surge protectors of different brands and models is thus a challenge we face. Classification: By composite structure ； There are several types of arresters available on the market today: 1) Gap-type —— open gap, closed gap. 2) Discharge tube-type —— open discharge tube, sealed discharge tube. 3) Varistor-type —— single-piece, multi-piece. 4) Suppression diode-type. 5) Varistor/gas discharge tube combination-type —— simple combination, complex combination. 6) Silicon carbide-type. Based on their protective functions, they can be classified as open-circuit arresters, short-circuit arresters, or switch-type and voltage-limiting types ； Based on their operating condition (installation type), they can also be divided into parallel arresters and series arresters.
