Thyristors, a family of four-layer semiconductor devices including silicon-controlled rectifiers (SCRs), TRIACs, and gate-turn-off thyristors (GTOs), are pivotal in modern electrical systems for their ability to control high voltage and current with precision. Unlike transistors, which excel in signal amplification, thyristors operate in a latching mode—once triggered, they conduct until the current drops below a threshold or polarity reverses. This unique behavior makes them indispensable in fi
