Thyristors are a type of semiconductor that acts as a switch and plays a vital role in today\'s modern electrical systems. The most commonly used type of thyristor is the silicon-controlled rectifier, or SCR. The MCR68-002 is one of the most popular SCR devices available and is used in a variety of applications, from industrial motor control to power supplies. In this article, we will examine the application field and working principle of the MCR68-002.

The MCR68-002 is a three-terminal SCR device that is highly reliable, easy to use, and cost-efficient. It is typically used in DC power control applications that require a large current handling capacity and high surge and surge current capability. It can also be used in AC power switching applications, such as in inverters, pulsewidth modulators, and light dimmers.

The key feature of the MCR68-002 is its gate trigger voltage, which can be adjusted to control the flow of current. This feature allows it to be used in a wide range of applications, from lighting and motor control to power protection. It also has a low trigger current, which helps reduce power consumption and voltage drop. As with any other SCR device, the MCR68-002 also has a built-in thermal protection unit to prevent any possibility of overheating.

The MCR68-002 works on a simple principle whereby its gate allows the current to flow when it is triggered. The device is initially turned off and no current flows. When a small amount of current is applied to the gate, it starts to conduct and the current flow increases until the device reaches its maximum current rating. This is known as the holding current. To turn off the MCR68-002, the gate current must be briefly reduced or the gate voltage raised.

The MCR68-002 is designed to withstand surge currents up to several hundred amps and is also built to withstand reverse voltages. It has a high breakdown voltage capability and can handle high dv/dt. To ensure optimum performance in all applications, it is recommended that the MCR68-002 be used together with a snubber circuit. This circuit will help to reduce any initial voltage spikes and ensure smooth operation of the device.

The MCR68-002 is a versatile SCR device that is used in many different applications. Its low on-state voltage drop, low power consumption, and high surge current capability make it an ideal choice for applications requiring high current capability and flexibility. It also offers a cost-effective choice for power control applications and is a reliable switching device for inverters, pulsewidth modulators, and lighting dimming systems.
