IntroductionT9S7261403DH is a type of thyristor module manufactured by Infineon Technologies. It is a part of Infineon’s Smart Power Technology & System Solutions and is designed for applications involving high power and voltage. The module consists of four separate thyristors and associated components integrated into one module. It is designed to be a modular solution for power control applications in motor and motor control, power electronics and other industrial, commercial and appliance applications.Application Field:The T9S7261403DH is a universal, high-power thyristor module commonly used in the motor control, power electronics and other industrial, commercial and appliance applications. The module features four separate thyristors embedded in a single package, which makes it ideal for use in motor control and power electronics, as it allows for the incorporation of multiple thyristors into a single, modular solution. The inclusion of separate thyristors also allows for easy control of the circuit parameters and protection. The T9S7261403DH module is also suitable for use in a variety of other applications, such as in automotive applications, including fuel injection control and drive motors; in industrial and commercial applications, including power control and breaker systems; and in appliances such as air conditioners, refrigerators and washing machines. The versatility and high power of the T9S7261403DH makes it an ideal solution for any application.Working PrincipleA thyristor is a semiconductor device that controls the flow of electric current, and the T9S7261403DH module has four of them embedded in a single package. The thyristors are connected in parallel with one another, allowing them to switch on and off in order to control the flow of current. In order to operate the T9S7261403DH module, the circuit parameters need to be adjusted so that the on/off switching pattern can be controlled. This is done using the module’s external input circuits. Firstly, the gate voltage needs to be adjusted so that the thyristors can be activated; this is done by supplying the gate voltage VGG at the gate terminal of the module. Once the gate voltage VGG is set, current needs to be applied to the thyristors in order to switch them on. This is done by supplying the required anode voltage Viv at the anode terminal of the module. Once Viv is applied, the thyristors can then be switched on by controlling the gate voltage. The T9S7261403DH module also features protection circuits that protect the module against short circuits and over-voltage/over-current conditions. This is done by automatically turning off the thyristors when the external gate voltage or anode voltage exceeds the set values. The protection circuits also protect the module from ESD. ConclusionThe T9S7261403DH is a thyristor module manufactured by Infineon Technologies that is suitable for use in motor control and power electronics. It consists of four separate thyristors embedded in a single unit and features an external input circuit for adjusting the circuit parameters, allowing for the switching on and off of the thyristors. The module also features protection circuits that protect against short circuits, over-voltage/over-current conditions and ESD. The versatile nature and high power of the T9S7261403DH make it an ideal solution for many applications.
