FOD817C300W

Optoisolators - Transistor, Photovoltaic Output

The FOD817C300W is a type of optoisolator, also known as an optocoupler, which is a device used to isolate electrical circuits from one another to prevent the affects of electrical noise. The device is most commonly used when inverting signals in electronic equipment or isolating two devices which have different levels of direct current, or DC.

The FOD817C300W has a specific application field and working principle. The device has a built-in high temperature NPN transistor which is mounted in a hermetically sealed 7-pin DIP package. The transistor has an isolation voltage rating of up to 2500V rms, making it suitable for use in high voltage applications. The device uses a photovoltaic output to provide electrical isolation between the input and output circuits. When a voltage is applied to the input of the device, light is generated inside the package and this light is then converted into an electric current by the photovoltaic cell. The output current is then applied to the collector of the transistor, creating a current in the output circuit.

The FOD817C300W has a number of features which make it a highly effective device. The transistor has a high speed switch-on time of 1.5µs, making it suitable for use in fast switching operations, and the internal protection circuitry ensures that the device can withstand reverse branch voltages. The device has a wide supply voltage range of 8V to 40V and a high common-mode transient immunity level of 1500V/µs, making it suitable for high voltage applications. The device is also designed to work at temperatures of up to -40°C to +125°C, making it suitable for use in a variety of temperature sensitive environments.

The FOD817C300W can be used to provide electrical isolation between two devices of different voltage levels. This is because the device is able to convert the voltage from the input device and apply it to the collector of the transistor, creating a current in the output circuit. This can be used to ensure that devices of different voltage levels can interact without causing short circuits.It can also be used to isolate devices from environmental electrical noise, and to protect circuits from overvoltage.

In conclusion, the FOD817C300W is a highly effective optoisolator with a wide variety of applications. The device has a built-in high temperature NPN transistor, a wide supply voltage range, and a high common-mode transient immunity level. The device is also suitable for use in high voltage applications, and can be used to provide electrical isolation between two devices of different voltage levels. This makes the FOD817C300W an ideal choice for use in a variety of applications.
