TS1220-600B

Thyristors - SCRs are a family of semiconductor devices mainly used as switches in electrical circuits in power electronics. The TS1220-600B is a type of SCR (silicon controlled rectifier) which can be used as a switch to regulate the flow of current in a circuit. It is designed with a reverse blocking voltage of 600V and a continuous current rating of 25A. This makes it suitable for a range of applications in motor control, lighting, and all areas of power control systems.

The working principle of the TS1220-600B is to use an external trigger voltage to control the gate (anode) and turn the thyristor ‘on’ or ‘off’. The gate voltage needs to be positive, in order for the thyristor to remain in the ‘on’ state, and a negative gate voltage will switch it off. The gate current is typically very small compared to the load current, so it can be controlled by a low-power electronic circuit. Once the TS1220-600B is ‘on’, it will stay in this state until the current in the circuit drops below a certain level, which is called the ‘Holding Current’. The thyristor will then switch ‘off’.

The TS1220-600B is designed for use in high-power applications, as it can handle both AC and DC current and can carry up to 25A continuously. It is also designed to offer very low ‘on-state’ voltage drop, which makes it suitable for use in speed control applications and other power circuits which require high efficiency. The high reverse blocking voltage and fast switching time of this particular SCR also make it suitable for use in circuits which require high-sensitivity control, such as in dimmable lighting systems.

The TS1220-600B is widely used in motor control circuits, and is a popular choice in AC and DC servo systems. Its reverse blocking voltage and fast switching time make it ideal for these applications, as it can regulate the switching of current in both the forward and reverse directions. In addition, the thyristor’s high-current handling capacity, low ‘on-state’ voltage drop, and high efficiency make it suitable for use in power-supply circuits and other industrial applications. The TS1220-600B can also be used in inverters and is a popular choice for applications where fast switching is required, such as in welding machines and induction motors.

In summary, the TS1220-600B is a type of SCR (silicon controlled rectifier) which offers excellent performance in a range of high-power applications. It offers a reverse blocking voltage of 600V and a continuous current rating of 25A, allowing it to regulate the flow of current in both the forward and reverse directions. Its high-current handling capacity, low ‘on-state’ voltage drop, and fast switching time make it ideal for use in a variety of applications, such as motor control, lighting, power supply, and other industrial applications.
