Optoisolators are electrical isolators that use a light source, such as an LED or laser diode, to transfer electrical signals between two isolated circuits. The TPC817S1D RAG is an optoisolator in the family of transistor-photovoltaic output (TPO) optoisolators. This optoisolator combines a high voltage phototransistor output with an operation that switches from a conductive to a nonconductive state.

This optoisolator is designed to operate with inputs as low as 2V and outputs as high as 150V. It offers excellent insulation characteristics with a maximum isolation voltage of 5kV, and a dielectric strength of 6V/μs. It has a low on-resistance of 10Ω, and a high switch current of 20mA, making it an ideal choice for a wide range of applications with different levels of signal requirements.

The application fields of the TPC817S1D RAG optoisolator include opto-coupling for voltage/current monitoring, touch sensing, low-voltage analog/digital opto-interfaces, and electrical isolation in automotive and industrial control systems. It is suitable for use in both consumer and automotive electronics, including automotive road lighting systems, automotive wiring systems, and automotive audio and navigation systems.

The working principle of the TPC817S1D RAG optoisolator is based on the photovoltaic effect. When placed in a circuit, the input voltage will cause the LED to emit light, which in turn will be absorbed by the photoreceptor, such as a phototransistor or photo-diode, resulting in the generating of an electrical current. This current will then travel to the output, creating an electrical connection between the two circuits. The amount of current that is produced is dependent on the amount of light being emitted by the LED, and the strength of the photoreceptor.

The TPC817S1D RAG optoisolator is a stable, reliable, and easy to use device. It offers fast response times, making it suitable for high speed applications, and can be used in high temperature environments, making it ideal for automotive and Industrial environments. It also features an LED reverse voltage protection, which prevents damage to the device in the case of an accidental reverse connection.

The TPC817S1D RAG optoisolator is an ideal choice for a variety of high voltage applications. Its low on-resistance and high switch current make it an excellent choice for voltage/current monitoring, touch sensing, and low-voltage analog and digital opto-interfaces. Its fast response time and excellent insulation characteristics make it an ideal choice for automotive and industrial control systems.
