Thyristors

A Thyristor is a solid-state semiconductor device, used to control alternating currents (AC) in high-voltage phase control applications.

The three-lead thyristor device is conducting when the gate receives a current trigger, and continues to conduct while it is forward biased and the voltage across the device is not reversed. With RMS current ratings up to 80 A and voltage ratings up to 1200 V, a thyristor is designed in AC circuits, resonant-pulse mode converters and rectifier-bridge converters.

A logic-level thyristor is easy to drive at a very low gate trigger current. A High-temperature thyristor extends the operation of the application up to 150 °C, while offering an improved dynamic performance. That includes automotive-grade versions. Often a thyristor is used for circuit protection in home appliance, electrical tool and motor control applications. The Thyristor is synonymous to Silicon-Controlled Rectifier (SCR).
