Functionality:

The ABB 5SHY3545L0009 thyristor functions as a switchable rectifier, controlling the flow of electrical current in a circuit. When a sufficient gate current is applied, the thyristor switches from a non-conducting (blocking) state to a conducting state. Once triggered, the thyristor remains in the conducting state as long as the anode-to-cathode current exceeds the holding current. Removal of the gate signal has no effect on the conducting state; the thyristor will continue to conduct until the anode current falls below the holding current or the reverse voltage exceeds the breakdown voltage.

This ability to control current flow makes thyristors ideal for applications such as motor control, power regulation, and welding, among others.
