Thyristors - SCRs - Modules

The T640N12TOFXPSA1 is a type of thyristor that is part of the SCR module family. This particular module is a high power thyristor and is designed specifically for use in applications that need to switch a high current at high frequency. This type of thyristor is especially useful for switching of high frequency digital signals such as those used in television and radio broadcasting.

Application Field

The main application field for T640N12TOFXPSA1 is in power electronics. It can be used for the control of medium to high power switching in applications such as AC switching, DC switching, resonant inverter bridges, and high frequency SMPS.

Due to their high current capacity, these SCRs are also used in motor speed control and regulation, power supply interconnection, used in high power rectifiers, lighting control, and adjustable speed drives.

Working Principle

The working principle of the T640N12TOFXPSA1 is based on the principle of the thyristor. It is made up of two p-n junctions that are connected in opposite directions. When a forward voltage is applied to the thyristor, a current flows across the two junctions and sets up a latching action that keeps a current flowing through the device even after the voltage is removed.

A signal current is then applied that causes the SCR to switch into a conducting state and allow a high current to flow through the device. When this signal current is removed, the thyristor immediately switches back to an off state. The speed of this switching is determined by the rise time of the current.

The T640N12TOFXPSA1 is designed to be very efficient in terms of power loss and switching speed. It is capable of switching currents up to 550A and voltages up to 650V. It also has a fast switching time that can reach frequencies up to 10kHz.

The T640N12TOFXPSA1 is a reliable and efficient thyristor that is capable of switching large amounts of current at high frequencies. With its high efficiency and fast switching time, it is an ideal choice for applications requiring power switching.
