Thyristors - SCRs

TN1215-800G-TR is a bidirectional solid-state switch based on Silicon Controlled Rectifier (SCR) technology. It is engineered to provide over-voltage and over-current protection as well as low EMI/RFI, low performance AC and DC circuit breaker. As a type of advanced semiconductor device, SCRs are comprised of three terminals - an Anode "A", a Cathode "K", and a Gate "G". The TN1215-800G-TR is specially designed for use in sensitive industrial applications, such as in motor control, power conversion, and lighting control. It is also a suitable choice for controlling the speed and plugging force of various types of industrial machinery.

Application Field

Fans: TN1215-800G-TR can switch on/off, adjust speed, and direction of motors! It is especially known for its fast switching capabilities and is a good choice for controlling fans. Motors: TN1215-800G-TR can be used to control motors and AC/DC drives. It’s perfect for applications where a rapid response and high load-shedding capability is needed, such as paint drying and wall paper printing applications. Lighting: Thanks to its fast switching time, TN1215-800G-TR is ideal for controlling lighting in all industrial settings. With its ability to provide uniform brightness levels and automated on/off functions, TN1215-800G-TR can significantly reduce power consumption in any operation.

Working Principle

The working principle of SCRs is simple: the Gate terminal triggers the device’s conduction action. When a positive pulse is applied to the Gate terminal, current is enabled to flow from the Anode to the Cathode. The size of the voltage applied to the Gate determines the amount of current allowed to flow - when a positive enough voltage is applied, current is allowed to pass through the device for an extended period of time. To turn off an SCR-based switch, two methods are available: Voltage Reverse Blocking and Latching. In Voltage Reverse Blocking, a negative voltage is applied to the Gate terminal to block its conduction action. In Latching, the conduction action is blocked with a surge of current applied to the Cathode. It can then be re-activated through the application of high-amperage current to the Anode. The TN1215-800G-TR is designed with both Voltage Reverse Blocking and Latching capability in mind, making it perfect for industrial applications requiring rapid response and high load-shedding capability.
