The TYN604 is 600V, 4A, Thyristor, SCR. A Silicon Controlled Rectifier (SCR) is a type of semiconductor device that is widely used as a switch or rectifier in power control and voltage regulation circuits. It is a three-layer, four-terminal device that can control the flow of current in either direction and provide full-wave rectification in power conversion applications.

The SCR can be triggered or turned on by a small trigger current or voltage applied to its gate terminal, and it remains in the conducting state as long as the anode-to-cathode voltage is positive and the gate trigger current is maintained. The SCR can be turned off by reducing the anode-to-cathode voltage to zero or by removing the gate trigger current.

SCRs are widely used in power control and regulation applications, such as lighting and heating control, motor control, battery chargers, and AC-to-DC power conversion, due to their high voltage and current handling capabilities, fast switching speeds, and high reliability.

The TYN204 ~ TYN1004 Family of silicon controlled rectifiers uses a high performance glass passivated technology. This general purpose Family of silicon controlled rectifiers is designed for power supplies up to 400Hz on resisitive or inductive load.

A triac consists of three layers of alternating P-type and N-type semiconductor material, arranged in a symmetrical structure. When the gate of the triac is triggered, it becomes conductive, allowing current to flow through the device. The triac will continue to conduct until the current falls below a certain threshold value, at which point it will turn off.

Triacs are widely used due to their high-power handling capability and low cost, making them a popular choice for industrial and consumer applications where AC switching is required. They are also used in applications where fast switching is needed, such as in switching power supplies, since they can switch on and off very quickly.
