TVSs are a form of transient voltage suppressor diode which protect against transient surges above their specified breakdown voltage rating. It is often used in electronic devices to provide protection from voltage spikes on the supply rail.

SR05.TCT Application Field and Working Principle

The SR05.TCT is a popular transient voltage suppressor diode with a maximum reverse breakdown voltage of 14V. It is commonly used to provide protection from voltage spikes on the supply rail of circuits in consumer electronics, and other electronic devices.

The SR05.TCT has 4 pins: 2 for the anode and cathode respectively, while the other 2 pins are for connection to a external resistor and capacitor respectively. When the reverse voltage across the diode is below the breakdown voltage, the diode operates in reverse blocking mode. When the input voltage exceeded the breakdown voltage, the voltage across the diode will be limited to that breakdown voltage, and the resulting current flowing through the diode will be limited by the external resistor and capacitor. This serves to reduce the voltage transient and protect the device from damage due to the voltage surge.

Apart from its uses above, the SR05.TCT is also used in automotive electronics, industrial electronics, aerospace electronics, LED lighting, solar cells, and many other applications. The device is also used in some household appliances for protection from voltage surges.

The SR05.TCT is a rugged device and can withstand up to 500V for up to 40ms while operating in reverse blocking mode, and up to 8A in clamping mode.

In summary, the SR05.TCT is a widely used and reliable transient voltage suppressor diode, used to suppress voltage spikes in consumer electronics and other applications. It has a maximum reverse breakdown voltage of 14V, and is able to withstand up to 500V for up to 40ms in reverse blocking mode.
