Circuit Protection

Circuit Protection components are used to protect electronic systems from overvoltage, overcurrent, electrostatic discharge, surge events and transient faults. They are widely used in industrial control, automotive electronics, communication equipment, power supplies, consumer electronics, computing systems, medical devices, IoT products and embedded applications.

This category includes TVS diodes, ESD protection devices, fuses, resettable fuses, varistors, surge protection devices, gas discharge tubes, PTC resettable protectors and related protection components. These devices are commonly selected based on working voltage, clamping voltage, current rating, response time, capacitance, package type, safety standards and application requirements.
