Optoisolators - Transistor, Photovoltaic Output

The TPC816S1C RAG is an optoisolator type photovoltaic output transistor from Toshiba that is used for various optical isolation applications. It is a voltage driven device that uses a photovoltaic cell as an output stage. The optoisolator type offers superior performance to standard opto-couplers, providing high levels of electrical isolation and excellent common-mode noise immunity.

Application Field

The TPC816S1C RAG is ideal for applications in which electrical isolation between two circuits or systems is essential, such as drives, inverters, power converters, industrial automation, motor control, and military/aerospace applications. It is also suitable for applications that require high levels of electrical noise immunity, such as medical and telecommunication equipment.

Working Principle

The TPC816S1C RAG optoisolator works by using a photovoltaic cell as an output stage. This photovoltaic cell is connected to the output transistor and consists of a light-sensitive diode and a transistor in series. When an electrical signal is applied to the input of the optoisolator, the photovoltaic cell will be activated and emit light. The light is focused by a lens and directed onto the light-sensitive diode, which generates a voltage at the junction of the diode and the transistor. This voltage is amplified by the transistor and output to the load resistor, thus providing electrical isolation between the input and output circuits.The optoisolator has several advantages over traditional optical couplers. As the device is driven by a voltage, the output voltage can be controlled more precisely. Additionally, the device provides a much higher level of electrical isolation than an optical coupler, providing greater noise immunity. The optoisolator also operates at higher temperatures and is more reliable than the traditional optical couplers.

Conclusion

The TPC816S1C RAG is an optoisolator type photovoltaic output transistor from Toshiba that is used for various optical isolation applications. It is used for applications in which electrical isolation between two circuits or systems is essential, such as drives, inverters, power converters, industrial automation, motor control, and military/aerospace applications. The optoisolator has several advantages over traditional optical couplers, including precise voltage control, higher levels of electrical isolation, and greater noise immunity.
