TRANSIENT VOLTAGE SUPPRESSOR DIODES MARKET OVERVIEW

The global transient voltage suppressor diodes market, valued at USD 2.74 billion in 2024, is projected to grow steadily to USD 2.87 billion in 2025 and reach USD 4.16 billion by 2033, maintaining a CAGR of 4.7% from 2025 to 2033.

Electronic components called transient voltage suppressor diodes are made to shield electronic equipment from transient voltage spikes. The terms Transient Suppressors, Surge Suppressors, and Transient Voltage Surge Suppressors (TVSS) are also used to refer to them. Different factors, such as lightning strikes, electrostatic discharge, or the switching of inductive loads, can cause voltage spikes or transients. Microprocessors, integrated circuits, and other delicate electronic components can sustain damage from these transients.

The breakdown voltage is the level at which TVS diodes are intended to clamp the voltage of the circuit to which they are connected. When the voltage rises over this point, the TVS diode conducts and absorbs the extra energy to keep the linked device from being harmed. TVS diodes are used in a wide range of electronic devices, including computers, telecommunications equipment, automobile electronics, and industrial control systems. They are available in a number of packages and sizes. To offer complete protection against voltage surges and spikes, they are frequently used in conjunction with other protection tools including fuses, circuit breakers, and surge protectors.
