FAQs

What is a thyristor and how does it work? A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. It functions primarily as a switch. In its basic form, the Silicon Controlled Rectifier (SCR), it remains non-conducting until it receives a brief pulse of current to its gate terminal. Once triggered, it latches on and continues to conduct electricity as long as the current flowing through it remains above a certain threshold, even after the gate signal is removed. It only turns off when the current drops below this holding level, typically when the AC voltage waveform crosses zero.

What are the main applications of thyristors? Thyristors are predominantly used for power control and switching applications. Their main uses include controlling the speed of AC and DC motors in industrial drives, regulating power in heating systems and light dimmers, managing voltage and current in power transmission systems like HVDC, providing over-voltage protection in electronic circuits, and functioning as key components in the inverters and converters used for renewable energy integration and uninterruptible power supplies (UPS).

What is the difference between a thyristor and a transistor? While both are semiconductor switches, they operate differently. A transistor is a continuously controlled device; the amount of current flowing through its collector-emitter path is proportional to the current applied to its base. A thyristor, once triggered by a gate pulse, latches into the on-state and remains conducting independently of the gate signal until the main current is interrupted. Transistors are generally used for amplification and lower-power switching, whereas thyristors are favored for handling very high power levels and in AC power control scenarios.

What are the advantages of using a thyristor? Thyristors offer several key advantages. They are capable of handling very high voltages and large currents, making them suitable for heavy-duty industrial applications. They have a simple control mechanism requiring only a brief gate pulse to trigger conduction. They exhibit low on-state power loss, which translates to high efficiency in power control. Furthermore, they are known for their robustness, reliability, and long operational life, especially in high-power environments.

What is a Triac? A Triac is a specific type of thyristor. The key difference is that a standard thyristor (SCR) is unidirectional and can only conduct current in one direction. A Triac is bidirectional, meaning it can conduct current in both directions when its gate is triggered. This makes the Triac particularly useful for controlling AC power, as it can regulate power during both halves of the AC cycle, which is why it is commonly found in applications like AC motor speed controls, light dimmers, and electronic switches for household AC lines.

What are some leading companies in the thyristor market? The thyristor market is served by several established global semiconductor manufacturers. Prominent companies include Infineon Technologies, STMicroelectronics, ON Semiconductor, Vishay Intertechnology, Littelfuse, and Mitsubishi Electric. These companies are recognized for their technological expertise, extensive product portfolios covering various thyristor types and ratings, and their strong global presence in supplying components to the industrial, automotive, consumer electronics, and energy sectors.
