Thyristors are semiconductor devices that can be used as switches in electrical circuits. A thyristor, commonly referred to as a SCR (silicon controlled rectifier), is made up of an arrangement of four layers of silicon material, each layer being a different type of semiconductor. The SCR contains two main layers, the gate layer and the main layer. The main layer is made up of two pieces of silicon, each one having a different conductivity from the other. The gate layer is made up of two additional pieces of silicon, acting as a control layer for the main layer. The combination of these four layers allows for the device to be used as either an ‘on’ or ‘off’ switch in electrical circuits. The TIC126M-S SCR is particularly useful for the protection of inverters, converters and power supplies due to its high voltage and current ratings.

One of the main applications of the TIC126M-S SCR is power electronics, more specifically used to convert AC to DC power. This SCR can be used in a bridge rectifier circuit, used to control the voltage and current in a power supply. This SCR is especially useful as it can be used to control a high voltage, up to 600 volts, and a high current up to 30 amperes. This makes the TIC126M-S the ideal device for many power supply applications. It is also used to control the speed of electric motors, as well as back-up protection from over-voltage or under-voltage circuits.

The working principle of the TIC126M-S can be divided into four parts: conduction and blocking, turn off, reverse blocking and dynamic dV/dt protection. The device can conduct and block currents from both directions; to turn it off, turn-off signals need to be applied external to the circuit. Its reverse blocking characteristics are important to prevent damage to the circuit and ensure that no current is flowing in the wrong direction. The dynamic dV/dt protection is a feature of the TIC126M-S that supplies a voltage-protection algorithm, ensuring that the device can handle high voltage transient spikes. All these features combined make the TIC126M-S an ideal choice for controlling power electronics circuits.

In conclusion, the TIC126M-S is a high-performance SCR, suitable for a wide range of power electronics applications. It offers great protection against over-voltages and under-voltages, as well as fast switching speeds. Its high voltage and current ratings, combined with its reverse blocking and dynamic dV/dt protection, make it a reliable choice for many different circuits.
