Arcade machines, with their intricate electronics and high-power components, are highly susceptible to voltage spikes and transients that can cause irreversible damage. To safeguard these gaming systems, various types of transient voltage suppression (TVS) devices are employed. The most common ones include Transient Voltage Suppression Diodes (TVS Diodes), Metal Oxide Varistors (MOVs), and Gas Discharge Tubes (GDTs). TVS Diodes are widely used for their rapid response time and ability to clamp voltage spikes effectively, making them ideal for protecting sensitive integrated circuits. MOVs, known for their high energy absorption capacity, are often deployed in power supply lines to handle larger surges, such as those from lightning or utility switching. Additionally, ESD (Electrostatic Discharge) protection devices are crucial for guarding against static electricity, which can harm control panels and coin mechanisms. Proper implementation of these TVS methods ensures the reliability and longevity of arcade machines, minimizing downtime and repair costs. Regular maintenance and correct selection based on the machine's specific voltage and energy requirements are essential for optimal performance.
