Thyristors -- SCRs are solid state components which were invented in 1957. The TCR22-675 is an example of an SCR that is used mainly in switch mode power supplies, inverters and rectifiers. It is also used in some lighting applications. This article will explain the application field of the TCR22-675, and its working principle.

Application Field

The TCR22-675 is mainly used in switch mode power supplies (SMPS). It is a control element for controlling the output voltage. It is also used in lighting, inverters, and rectifiers. The TCR22-675 has a high peak current rating, which makes it suitable for applications requiring high current switching.

Working Principle

The TCR22-675 is an SCR, which stands for Silicon Controlled Rectifier. It is a four-layer, three-terminal device, consisting of an anode, a cathode and a gate. This device works on the principle of a thyristor, which is a semiconductor switch. When a voltage is applied to the gate of the TCR22-675, it is switched “on.” When the gate voltage is removed, the device is switched “off.” The device can also be switched “on” and “off” manually by pressing a switch.

The TCR22-675 is a sensitive, bidirectional device and has a high peak over-current rating. It has low forward voltage drop, which helps to reduce losses. This device is used primarily to control power in DC and AC systems, and is suitable for applications where fast switching is required.

Conclusion

The TCR22-675 is a sensitive, four-layer, three-terminal device which is mainly used in switch mode power supplies, lighting, inverters and rectifiers. It works on the principle of a thyristor and is switched “on” and “off” manually or by a voltage applied to its gate. The TCR22-675 has a high peak over-current rating, a low forward voltage drop, and is suitable for applications requiring fast switching.
