Overview of protective devices
Protective devices are divided into overvoltage protection and overcurrent protection. Overvoltage protection products mainly include semiconductor discharge tube (TSS), transient suppression diode (TVS), ceramic gas discharge tube (GDT), varistor (MOV), glass gas discharge tube (SPG), etc. overcurrent protection products mainly include fuse, self recovery fuse (PTC), etc;
