TVS – Thyristors

Thyristors, also known as Silicon Controlled Rectifiers (SCR), are a type of semiconductor power electronic switch. They are used extensively in AC to DC power conversion and offer several advantages over conventional power electronic switches, such as no contact between the anode and cathode, no arcing, and lower power consumption. This article focuses on the T10A140B thyristor and its application fields and working principle.

Application Fields of T10A140B

The T10A140B thyristor can be used in a wide variety of applications, including power conversion and motor control, power supplies, power factor correction, battery charging, and converters. It is a versatile, robust thyristor with excellent performance characteristics. This makes it suitable for both commercial and industrial applications.

Working Principle of T10A140B

The T10A140B thyristor is a four-layer semiconductor device that consists of a P-type base region, an N-type collector region, an N-type emitter region, and a gate region. When the thyristor is turned on, a current starts flowing from the anode to the cathode of the device. This current is controlled by the gate, which is connected to the trigger voltage. When the voltage is higher than the threshold voltage, the thyristor is in the forward conduction state. The thyristor can be turned off again by either reducing the current below the minimum holding current or by reversing the polarity of the gate voltage. When the thyristor is turned off, it behaves like an open circuit and no current flows through it.

Conclusion

The T10A140B thyristor is a highly versatile device with excellent performance characteristics. It can be used in a variety of applications such as power conversion, motor control, power supplies, and power factor correction. Its working principle is based on the forward conduction of current when the gate voltage is higher than the threshold voltage.
