Thyristors are semiconductor devices which are capable of controlling and managing the flow of current and voltage in electrical circuits. A TVS, or transient voltage suppressor, also known as a Transient Voltage Suppression (TVS) diode, is an electronic device that prevents voltage transients or spikes from damaging other electrical components. One of the most popular and widely used TVSs is the P3403AC69, which is designed to ensure the protection of downstream components in multiple applications.The P3403AC69 is a bidirectional thyristor which can be used in various applications as a voltage regulator, an overvoltage protection device, and an overcurrent protection device. It is a compact, surface-mount device which is able to dissipate 1500 watts of peak power, yet it requires very little board space, using only an SMA-6 package. The P3403AC69 is designed to remain functioning even when subjected to high frequency, short duration transients such as electrostatic discharges.The P3403AC69 is suitable for use in automotive, industrial, telecom, medical, and consumer electronic applications. In automotive applications, the P3403AC69 can be used to prevent damage to Control Area Networks (CANs) and other electronic control systems from voltage transients. In industrial applications, it can be used to protect low voltage power supplies and other high voltage equipment from damage due to power surges or spikes.The P3403AC69 is able to provide greater protection than traditional TVSs due to its dual breakdown capabilities. It has a low threshold voltage, allowing it to protect circuits from even very low voltages, such as those caused by electrostatic discharges. It also has a high breakdown voltage, which allows it to protect circuits from higher voltages, such as those caused by power surges or spikes.The P3403AC69 is a thyristor-based TVS that works by sensing overvoltages and triggering a flow of current in a short-circuit, effectively directing the high voltage away from the system. The P3403AC69 switches off when the excess current is dissipated, allowing the voltage to return to its normal level. The P3403AC69 is designed to absorb energy rapidly, minimizing the risk of overvoltage damage to connected components.The P3403AC69 is a reliable and robust thyristor solution for protecting against transient voltage spikes. It is capable of providing long-lasting protection for a variety of electrical and electronic components, including low voltage power supplies, CANs, and other electronic control systems. Due to its compact size and high power dissipation capabilities, the P3403AC69 is an ideal solution for a variety of applications.
