Thyristors – SCRs are commonly used in various applications where reliable control of current or voltage is required. The T7SH104054DN is a Thyristor-SCR based switching device that is frequently used for power control applications. It is an insulated gate bipolar transistor (IGBT)-controlled thyristor that consists of a rectifier diode, a thyristor, a control device and an input circuit.

The application field of the T7SH104054DN is mainly used in energy saving applications. It is primarily used in devices that require high power switching but with low power losses. It is capable of switching high voltage and high current with low losses and low on-state voltage drop. The T7SH104054DN can be used in AC motor speed control and other power-control applications like AC/DC converters, UPS, sinusoidal synchronous motor control, solar panel control, motor soft-start applications, and more.

The working principle of the T7SH104054DN is based on the principle of ‘on-state’ and ‘off-state’ operation. In the on-state operation, current flows through the power device when the gate voltage is applied, thus causing the power device to conduct. The device will stay in this on-state until the gate voltage is switched off or the applied current is reduced. In the off-state operation, no current flows through the device until the gate voltage is applied. Once the gate voltage is applied, current can then flow through the device.

The T7SH104054DN features a low forward voltage drop and low leakage current. The device is constructed with an oxide-based metal-oxide-semiconductor field-effect transistor (MOSFET) and an IGBT input gate circuit. The IGBT input circuit provides a low on-state voltage drop. The device is designed to provide low switching losses and fast turn-off times by combining the low on-state voltage drop of the MOSFET with the low leakage and fast turn-off times of the IGBT.

The T7SH104054DN is a very reliable, low-loss switch for power control applications that require low switching losses and fast turn-off times. The device is well suited for AC motor speed controls and other power control applications such as AC/DC converters, UPS, sinusoidal synchronous motor control, solar panel control and motor soft-start applications.
