Thyristors - SCRs are electronic devices that consist of at least four layers of alternating P (positive) and N (negative) type semiconductor materials. They are widely used in various power electronics applications like power control, switching, motor control, and protection. One of the most popular Thyristors - SCRs is TS420-600B.

The TS420-600B is a four-layer thyristor with a turn-off blocking and pulse trigger characteristics. It is mainly used in controlling high power loads and circuits where high voltage and short current pulses are required. It is usually preferred in applications where reliable operation, long service life, and fast turn-off operation is required. With its high power ratings, it can also be used in rectifiers, motor control, power supplies, and other consumer electronics.

In terms of its working principle, the TS420-600B is a current operated device. In other words, the device is activated is when the current rises to a certain threshold level. When the current reaches this level, it will cause the SCR to turn on, allowing the current to flow through. Once the current is switched off, the device will turn off, thus disconnecting the current from the other device.

The TS420-600B has wide range of applications, ranging from rectifiers and converters, to motor controls and protection. In rectifiers, this thyristor can be used to control voltage, current, and pulse waveforms efficiently. It can also be used in motor control circuits, where it can help regulate the speed and direction of the motor, as well as the torque. In protection applications, this device can be used as a fault indicator to detect high-current surges and short circuits.

In conclusion, the TS420-600B is a popular four-layer thyristor with a turn-off blocking and pulse trigger characteristics. It is mainly used in controlling high power loads and circuits, where high voltage and short current pulses are required. With its wide range of applications, from rectifiers and motor control to protection, it is ideal for many power electronics applications.
