Figure 1 shows a simple circuit of thyristor analogues that have a high input resistance and the ability to adjust the switching voltage. Both devices contain comparators U1.1 of the LM339 chip as an ...

Once activated, the thyristor remains on until the power is turned off or the circuit is reset. Thyristors are commonly used in motor speed controls, light dimmers, and power switching ...

This transformerless power supply circuit is designed for medium current applications. ... The transport of electric charge through the thyristor begins when the voltage on C4 drop below a specified ...

Littelfuse, Inc., has introduced an ultra-low capacitance protection thyristor. An ultra-low capacitance protection thyristor from Littelfuse, Inc., the SDP Series SIDACtor® Protection Thyristor ...
