Thyristors - SCRs

Thyristors - SCRs (Silicon Controlled Rectifiers) are a type of device used to control power in many different applications. They are especially useful in high-frequency applications, due to their relatively low on-state capacitance and very fast switching times.

The T72H0635B4DN is a 600V, 2.6A SCR. It has a gate trigger current of 1.3mA and a holding current of 1.1 A, which makes it suitable for both standard and high-frequency applications.

Application fields of the T72H0635B4DN

The T72H0635B4DN is designed for high-frequency switching applications, generally in the range of 10HZ to 10MHz. It is especially suitable for applications such as frequency converters, motor drives, automotive systems, UPS systems and inverters. The device is also suitable for heating and lighting control systems, medical equipment and aviation systems.

Working Principle of the T72H0635B4DN

A SCR is an ac to dc device, and works like a switch. When a voltage is applied to the device, the gate terminal is activated which causes current to flow through the device. This can be used to switch on a load and control the current being supplied to it.

When the voltage applied to the device is below the device’s trigger voltage, it does not conduct and the load will not be switched on or off. When the voltage exceeds the device’s trigger voltage, it will switch on and allow current to flow through the load.

The T72H0635B4DN also has a holding current, which is the minimum current required to keep the SCR in conduction, even when the applied voltage is below the original trigger voltage. When the current through the device is below the specified holding current, the SCR will turn off.

The T72H0635B4DN is a very reliable, powerful and versatile device, which makes it suitable for many applications. It is important to consider the device’s specific properties when choosing it for an application, as they can have a profound impact on the performance and reliability of the system.
