TVS - Diodes

What is TVS - Diodes: TVS Diode (Transient Voltage Suppression Diode) is a type of device designed specifically to protect sensitive electronic components from electrical transients or “spikes” in voltage. Transient voltage suppressor diodes are able to clamp any such spike at a safe voltage level, thus protecting the device from the sudden, potentially catastrophic increase in voltage, which could damage or destroy the device being protected.

SMCJ18CAE3/TR13 Application Field: SMCJ18CAE3/TR13 is a Unidirectional Transient Voltage Suppressor Diode specially designed for sensitive components from electrical transients such as ESD, Electrical Fast Transients (EFT) and much more. It can be used for different protection applications including consumer appliance, automotive, industrial, communication systems, consumer, etc.

Working Principle: The working principle of transient voltage suppressors is based on the switching action of the diode. When an overvoltage occurs, the diode starts to conduct and divert the charge to ground. This charge is then discharged through the diode, thus preventing the spike in voltage from reaching the device being protected. The voltage is clamped at a safe level, thus protecting the component from potentially catastrophic overvoltage.

Conclusion: TVS Diodes are an essential component in protection of electronic circuits from transient voltages. The SMCJ18CAE3/TR13 is a great solution for applications involving protection from spikes in voltage. Its working principle is based on the switching action of the diode, which allows it to divert any unwanted overvoltage away from the device, thus providing it with the necessary protection.
