Thyristors - SCRs:

Thyristors - SCRs are solid-state devices used in a variety of electronics applications. They work by applying a voltage across two terminals, which creates a current flow between them. This current flow then acts like a switch, allowing for conduction or blocking depending on the voltage applied. One of the most popular types of thyristors is the T600021804BT.

T600021804BT Application Field:

The T600021804BT is a Thyristor Surge Current Protection device, also known as a Transient Voltage Suppression Diode (TVS). It is designed to protect electrical circuits from transients and surges on an AC line and is suitable for high volume applications. It has a wide operating voltage range, low leakage current, and fast response time. Typical uses include automatic voltage regulators (AVRs), air conditioners, refrigerators, and other consumer electronics.

T600021804BT Working Principle:

When an AC voltage is applied to the T600021804BT, it will conduct current as soon as the voltage reaches its breakdown voltage. As the voltage continues to increase, it will cause an avalanche breakdown of the device. This will cause a large current to flow, which will reduce the voltage on the circuit to a safe level. The current will then be allowed to pass until the voltage on the circuit drops back below the device\'s breakdown level.

The T600021804BT is also capable of withstanding high transient current and voltage levels. It has a very low leakage current as well, which helps to reduce the risk of short circuits and other potential damage. The device is also able to quickly respond to transient changes, making it suitable for use in high-frequency applications and other demanding applications.

The T600021804BT can also be used in reverse blocking mode, where it will prevent current from flowing in the opposite direction. This is especially useful in the protection of sensitive load circuits. When the voltage on the load circuit exceeds the breakdown voltage of the device, it will block the current and protect the load.

The T600021804BT is also RoHS compliant, as well as UL, CSA, and VDE approved. This ensures that the device conforms to the highest standards in safety and quality. Additionally, the low capacitance makes it suitable for high speed applications, while the long service life and high reliability are particularly desirable for industrial use.
