Optoisolators are optoelectronic devices used to provide electrical isolation between two connected circuits. The TPC817S1C RAG is a Transistor, Photovoltaic Output Optoisolator which features a dual bi-directional AC/DC input and a dual bi-directional DC/DC output. It enables control signals from one circuit to be transmitted and received by another circuit without direct electrical contact between the two circuits.

Application Field

TheTPC817S1C RAG has a wide range of applications including household appliances, automotive electronics, LED/OLED displays, industrial equipment, and medical electronics. Its Transistor, Photovoltaic Output configuration improves performance and reliability in the most demanding environments. Its compact surface-mount package helps reduce PCB size and makes it suitable for use in high-density applications.

Working Principle

The TPC817S1C RAG is a Transistor, Photovoltaic Output Optoisolator that works by modulating a light source such as an infrared LED. The modulation of the LED causes a transmitting device (transmitter) in one circuit to send a signal to a receiving device (receiver) in another circuit. The receiver then converts the signal from light into electrical signals and isolates the two circuits. The TPC817S1C RAG is a dual bi-directional AC/DC and DC/DC optoisolator, meaning it can be used to send and receive signals in both directions.

The TPC817S1C RAG utilizes a photovoltaic output, which converts the optical signal from the LED into electrical energy. This energy passes between the signal and the ground pins on the receiver. When the signal is received by the receiver, a voltage is generated across the collector and emitter pins, which is then used to actuate an output such as a relay or other electronic component.

At the same time, the TPC817S1C RAG also provides protection against noise and interference. It does this by dissociating the sensitive electronic components of the two circuits from each other, preventing any high-frequency noise and other interference from affecting the performance of the connected devices.

The TPC817S1C RAG can also help reduce power consumption by limiting the amount of current that passes through the LED. In most cases, the LED only needs to be powered briefly to send and receive the signal. This reduces the amount of energy needed to power both circuits and leads to greater efficiency and cost savings.

The TPC817S1C RAG is a versatile and reliable optoisolator suitable for a variety of applications. Its compact package, dual bi-directional performance, and noise protection features make it a great choice for use in a wide range of industries and applications.
