Thyristors - SCR, commonly recognized as Silicon Controlled Rectifiers (SCR), are three-terminal semiconductor power switches used primarily in industrial and motor control applications. They are mainly used in applications where higher power control is desired along with a variety of less intrusive analog and digital control signals. The unique feature of SCRs is that they operate through a gate signal that needs to be maintained during the switch\'s operation. When the gate signal is removed, the SCR turns off.

The T700103004BY is a special type of SCR known as a Fast Switching Thyristor (FST). These are general purpose SCRs with higher switching speeds compared to standard SCRs. By utilizing the properties of FSTs, the T700103004BY can be used in a variety of applications that require extra speed, including AC power switches, motor and combustion engine control, and load shedding.

The T700103004BY is designed for fast switching and control, making it ideal for controlling higher power loads. Its switching speed can range from 10μs to 1μs, and its maximum average repetitive current (I_T) rating can be up to 400A. Its gate trigger current is low, ranging from 0.6 to 1.2 mA, while its gate trigger voltage can range from 1 to 10 V.

The T700103004BY SCR also combines low on-state voltage drop, low leakage current and low capacitance values with a fast, high frequency switching capability. It also has an operating temperature range of -40 to +125 degrees Celsius.

In terms of its working principle, the T700103004BY operates by introducing a low current gate signal which acts as a control signal to turn On the SCR. This gate signal, depending on the type of device, will be either AC or DC. This turns on the SCR and its semiconductor components, allowing forward conduction of the current. This is possible only if the current rating is less than the rated IT and the voltage rating is less than the rated VRRM. When the gate signal is extinguished (removed), the SCR turns off.

The T700103004BY is a special type of SCR that offers fast switching time, low voltage drop, and low leakage current. The fast switching speed makes it suitable for use in applications where higher power control is needed. Additionally, its low gate trigger current and low trigger voltage enable it to be used in a variety of applications, from AC power switches to motor and combustion engine control, as well as load shedding.
