More About Thyristors: In its most basic form, a thyristor has three terminals: anode (positive terminal), cathode (negative terminal), and gate (control terminal). The gate controls the flow of current between the anode and cathode.  The primary function of a thyristor is to control electric power and current by acting as a switch. For such a small and lightweight component, it offers adequate protection to circuits with large voltages and currents (up to 6000 V, 4500 A).  It is attractive as a rectifier because it can switch rapidly from a state of conducting current to a state of non-conduction. In addition, its cost of maintenance is low and, operating under the right conditions, remains functional in the long term without developing a fault. A thyristor with a P-N-P-N structure has three junctions: PN, NP, and PN. If the anode is a positive terminal with respect to the cathode, the outer junctions, PN and PN are forward-biased, while the center NP junction is reverse-biased. Therefore, the NP junction blocks the flow of a positive current from the anode to cathode. The thyristor is said to be in a forward blocking state. Similarly, the flow of a negative current is blocked by the outer PN junctions. The thyristor is in a reverse blocking state.

To apply thyristors successfully when designing circuits, it is important to know their unique characteristics, limitations, and their relationship with the circuit.  Read more about how thyristors work, various types, and how to select the right type for your required application in our blog: “What is a thyristor?
