The VOM618T is an opto-isolator which provides electrical isolation between input circuitry and output circuitry. It is specifically designed for applications where electrical noise and other high-frequency signals are present.

The VOM618T consists of an infrared LED and a photopransistor, both enclosed in an opaque package. The outer package provides physical and electrical insulation between input and output stages, thus providing electrical isolation. The LED is connected to the input stage and the phototransistor is connected to the output stage.

When power is supplied to the input stage, the infrared LED is illuminated. This light is then detected by the phototransistor, which produces a current in proportion to the light intensity. This current is then amplified by the output stage which produces an output voltage which is proportional to the input current.

The VOM618T is suitable for applications requiring protection of input circuitry from sources of electrical noise. It is commonly used in motor control, audio systems, sensor signal isolation, automotive powertrain and lighting applications.

The VOM618T is also suitable for power switch applications operating in power modes from low voltage to high voltage. It is used in applications requiring voltage protection and current limitation. In addition, it provides a secure connection between high voltage and low voltage circuits.

The VOM618T has a wide operating temperature range and is available in a variety of package types. It is both energy efficient and cost effective.

In summary, the VOM618T is a versatile opto-isolator providing electrical noise protection, current and voltage protection, and secure connections between circuits. It is suitable for a wide range of applications, making it an ideal choice for many applications that require isolation between input and output stages.
