Market Definition
The varistor and gas discharge tube (GDT) encompasses components designed to protect electronic circuits and systems from voltage surges and transient events. Varistors, primarily metal oxide varistors (MOVs), offer voltage-dependent resistance that clamps excess voltage to prevent circuit damage, while GDTs provide high-energy surge protection by conducting large currents to the ground when a specific breakdown voltage is exceeded. These components are essential in applications such as consumer electronics, telecommunications, industrial equipment, automotive systems, and power distribution networks, where reliable protection against overvoltage, lightning strikes, and electrostatic discharge (ESD) is critical to ensuring device longevity and safety.
