MCR106-8G

Thyristors - SCRs

The MCR106-8G is a sensitive gate, low-power silicon controlled rectifier (SCR) designed with an 800V voltage holdoff capability and a peak pulse current of 8A. This device is ideal for applications such as timing relays, AC switches and motor control circuits. This component also features a very low gate trigger current, low gate trigger voltage and a high junction temperature rating.

Application Field

The MCR106-8G is mainly used in medium-power electronic control systems. It can be used effectively in applications such as lighting controllers, electrical equipment and motor control. The component is particularly useful when the control circuit needs to interact with external events or a power system. It is also used in medium-power switching, phase cut dimmer, soft starter, voltage regulators and AC-DC converters.

Working Principle

The MCR106-8G works by controlling the flow of electrical current between two points. When the current applied to the device exceeds a certain threshold, the SCR turns on, allowing the current to flow. When the current goes below the threshold level, the SCR turns off driving the current off. This behavior can be controlled by a gate current, which is the amount of current needed to trigger the device on and off. The cut-off and holding currents of the MCR106-8G determine how much current is required to turn the device on and off. The turn-on and hold-off voltages of the device are also able to limit the amount of current that can be passed through the device.

Advantages

The MCR106-8G offers several advantages over other similar devices. Its two-pin configuration, low gate trigger voltage, low gate trigger current and high operating temperature rating, make it ideal for use in applications where space or power is an issue. In addition, the device can handle very high voltage, up to 800V, allowing it to be used in situations where voltage could otherwise pose an issue. The low on-state resistance makes the device efficient, meaning less power is consumed in the system.

Disadvantages

The main disadvantage of the MCR106-8G is its high on-state voltage drop. This can cause a significant amount of power to be wasted in a system if not managed properly. Additionally, the device is not suitable for low-power applications due to its high current requirements.

Conclusion

The MCR106-8G is a sensitive gate, low-power silicon controlled rectifier (SCR) designed with an 800V voltage holdoff capability and a peak pulse current of 8A. It is ideal for applications such as timing relays, AC switches and motor control circuits. The device offers several advantages, such as its two-pin configuration, low gate trigger voltage, low gate trigger current and high operating temperature rating. However, it must be managed properly due to its high on-state voltage drop.
