TVS stands for Transient Voltage Suppressor, a type of protective device that is used to protect sensitive electronic circuits from voltage spikes and other electrical transients. TVS devices are designed to rapidly clamp down the voltage to a safe level when a transient occurs, preventing it from damaging the protected circuit.
TVS devices are often used in place of traditional protective devices such as fuses and circuit breakers, which can be slow to respond to transients and may not provide sufficient protection. TVS devices are available in a wide range of voltage and current ratings to suit different applications, and can be used in both AC and DC circuits. They are typically small and lightweight, making them suitable for use in portable electronic devices and other applications where space is limited.
