An overview of protection devices

An overview of protection devices

Protection devices are divided into overvoltage protection and overcurrent protection, overvoltage protection products mainly include semiconductor discharge diode (TSS), transient suppression diodes (TVS), ceramic gas discharge diode (GDT), varistors (MOV), glass gas discharge diode (SPG), etc., overcurrent protection products mainly fuse (FUSE), resettable fuses (PTC), etc.;

Key Features and Benefits of transient suppression diodes:

Complete product range

Fast response

voltage

Repeatable

Main applications:

Security industry: POE protection, RJ45 protection, AC/DC power protection, I/O, data cable, DVR/NVR and other interfaces;

Automotive electronics: ABS, CAN-BUS, window regulators, wipers, car chargers, car DVD audio and video systems, GPS locators, car instruments;

Communication industry: base station, telephone, fax machine, POS machine, Modem, xDSL terminal, program-controlled switch office equipment, RS232/422/423/485, 10/100M Ethernet, Gigabit Ethernet, CATV equipment
