T1220N20TOFVTXPSA1 Datasheet/PDFThyristors - SCRs - Modules
The T1220N20TOFVTXPSA1 is a three-terminal integrated silicon controlled rectifier (SCR) module that is specifically designed for fault-current limiting and circuit protection applications. It has a solidstate design with a surge rating of up to 200 amperes which allows it to withstand short circuit faults with great precision. This module is ideal for use in industrial, automotive, telecommunications, and power distribution applications where high current carrying capability and reliable circuit protection are required.
The T1220N20TOFVTXPSA1 module is composed of a thyristor, a thermal sensor, and a switch. The thyristor is a three-terminal semiconductor device that is used for controlling the switching speed, power rating, and current level in the application. The first two terminals are the anode and cathode, and the third terminal is the gate terminal, which is typically used for gate current control. The thermal sensor is designed to monitor the temperature of the module and trip if the temperature exceeds its programmed capability.
The T1220N20TOFVTXPSA1 module works by allowing current to flow only when the gate voltage is applied, and when the gate current is kept at a constant level. When the current jumps above its maximum limit, the module will trip, and shut down the current flow. This allows the module to protect the circuit from overcurrent, short-circuit, or other fault conditions. As the crew at Power Resistance Technologies explains, “It is important to note that when the current passes through the thyristor junction, it is easy to cause damage due to the high power velocity. Therefore, the thyristor module needs a high temperature protection device in order to prevent damage due to overheating.”
The T1220N20TOFVTXPSA1 module is an excellent choice for applications that require reliable and precise control of the current. It is especially useful for applications with high peak current operation or those that require a high level of temperature protection. Its high surge and temperature rating allow it to withstand short circuit faults while ensuring that the circuit remains safe and reliable. This makes it an ideal choice for industrial, automotive, telecommunications, and power distribution applications.
In conclusion, the T1220N20TOFVTXPSA1 module is an ideal choice for circuit protection and fault-current limiting applications. Its solid-state design and high surge rating allow it to provide reliable circuit protection and precise control of the current. In addition, it provides a high level of temperature protection to ensure that the circuit remains safe and reliable. This makes it an ideal choice for industrial, automotive, telecommunications, and power distribution applications.
