Optoisolators are widely deployed in a broad variety of electrical and electronic circuits for a range of applications. One such device is the MOC5008SVM, or MOSFET Output Optoisolator with Schmitt Trigger Input. This device is ideal for a variety of applications, including industrial, automotive, military and aerospace applications. In this article, we explore the application fields of the MOC5008SVM and its working principle.

Application Fields

The MOC5008SVM benefits from a number of features that broaden its application fields. It is optimized for low-output current applications and can be used with logic systems such as TTL and HCMOS. It is also available in insulated packages, making it suitable for a range of high voltage applications. Additionally, the device features ESD protection in excess of 6 kV HBM, and an LED reverse bias connection of up to 50V.

The device is widely used in a variety of automotive, industrial and military applications. Its features make it well-suited for automotive applications including engine control, lighting systems, door locks and audio systems. In terms of industrial applications, the device can be found in pumps and motors, heaters, and digital displays. It is also employed in military and aerospace applications such as aircraft environmental control systems.

Working Principle

The MOC5008SVM is an optoisolator, which essentially performs the task of isolating the controlling logic circuit from the controlled load circuit. It works by using a light-activated switch. This light-activated switch is powered by a light-emitting diode (LED), located in the circuit. When the LED is activated, it sends a signal to the photo-sensitive switch to close the switch connection and transfer the output signal only when the input signal meets the preset criteria.

In the case of the MOC5008SVM, the device is readily modulated to the desired current and cutoff voltage requirements. The device has two different voltage thresholds; a low-level threshold voltage (Vth1) and a high-level threshold voltage (Vth2). When the input voltage rises above Vth1 and remains above Vth2, the output signal is activated. When the input voltage falls below Vth2 and remains below Vth1, the output is deactivated. In this way, the output remains in the “ON” state as long as the input voltage is between these two preset voltage thresholds.

Conclusion

In summary, the MOC5008SVM is an optoisolator that is widely deployed in a broad range of electrical and electronic circuits. It features a variety of features that make it suitable for automotive, industrial, military and aerospace applications. The device works by using a light-activated switch that is powered by an LED. This switch closes the connection between the input and output only when the input voltage meets the pre-set voltage thresholds, thus providing isolation between the controlling logic circuit and the controlled load circuit.
