Optoisolators are electronic components used to isolate analog and digital input and output signals, allowing the sharing of isolated power and ground supply lines. The FODM8801CR2V is a high temperature, high reliability, transistor output optoisolator available in a titanium TO-252 package. It has an operating temperature range from -55°C to +150°C and an isolation voltage rating of 5000Vrms.

Application Field

The FODM8801CR2V is primarily designed for industrial applications, such as those found in harsh industrial environments where shock, vibration, dust and dustproof requirements must be met. The optoisolator features a high dielectric strength between the input and output terminals and can be used in applications where noise or electrical surge protection is required. It is also suitable for use in motors, transformers, power supplies, displays and sensing applications.

Working Principle

The FODM8801CR2V is made up of a phototransistor and an infra-red diode optically coupled together in a plastic package. The device is activated by the infrared light launched from the diode which is then detected by the phototransistor, generating a transistor output. The isolation gap between the input and output circuits are typically greater than 10,000Vrms, providing high isolation and reliable operation. The device also features a reverse transfer CT1 ratio of 1:20, which limits the amount of current transmitted from the output stage to the input stage.

The optoisolator is also characterized by a high EMC (electromagnetic compatibility) immunity and a fast response time of 6.5ns. The device is capable of handling high current loads up to 250mA at a voltage rating of 60V. The FODM8801CR2V can withstand high temperature (up to +150°C) and vibrating applications, such as motors, transformers and power supplies.

Conclusion

The FODM8801CR2V optoisolator is a high temperature, high reliability, transistor output optoisolator available in a titanium TO-252 package. It offers a high dielectric strength between the input and output terminals and good EMC immunity. It is suitable for applications in harsh industrial environments, motors, transformers, power supplies, displays and sensing applications, providing reliable operation and limiting the amount of current transmitted from the output stage to the input stage.
