Optoisolators - Transistor, Photovoltaic Output

The FOD817CS is a type of optoisolator, currently one of the most popular components of its type used by many engineering professionals in the market. An optoisolator is designed to electrically separate two circuits, usually for safety purposes. The FOD817CS optoisolator is a component with a transistor, photovoltaic output. This type of optoisolator transduces electrical signals into light signals, which is then increases the insulation distance and voltage rating of the opto-isolator.

To understand the application field and working principle of the FOD817CS, a deeper understanding of optoisolators in general is needed. Most optoisolators consist of an infrared light emitting diode (LED) and a phototransitor that are separated by a glass or plastic. When the LED emits light, it is sensed by a phototransistor, which is a photo conductor and amplifying device. Upon sensing light, the phototransistor turns ‘on’, and electrons flow through it, allowing current to flow.

The FOD817CS is typically used for the amplifying and isolation of analog signals. The FOD817CS has a typical current transfer ratio of 10mA, which means the LED current must be at least 10mA to ensure that the output transistor is ‘on’. It has a highly flexible insulation resistance of 10000 Megaohms at 500 V, with a dielectric strength of 5KV AC. The output voltage of the FOD817CS is around 0.4 volts, and it consumes around 5mA when ‘on’. It is also able to withstand up to 70°C temperature, so it is suitable for industrial applications.

When it comes to working principle, the FOD817CS opto-isolator allows for a perfectly isolated connection between two circuits. This is done by using light to keep the two circuits completely compatible. 1st by having the input transmit an electrical signal to the LED, the LED then emits a light signal, which is sensed by the phototransistor. The phototransistor then allows current flow through it, and the output circuit gets the electrical signal from the phototransistor. This method is used to effectively transfer analog signals through isolation, with no loss of signal clarity or accuracy.

The FOD817CS optoisolator is an effective way to isolate two electrical circuits from each other. It allows engineers to easily transmit an analog signal in an isolated manner, with no signal distortion or interference. Its high insulation resistance and wide temperature tolerance make it a perfect choice for industrial applications. Indeed, the FOD817CS is one of the most popular optoisolators available in the market today.
