FOD617D300W

Overview

The onsemi FOD617D300W is a single-channel photovoltaic output optoisolator designed for high-reliability applications. It features a GaAs infrared LED coupled to a photovoltaic detector, providing electrical isolation with a rated voltage of 5000Vrms. The device utilizes a 4-pin MDIP package and supports through-hole mounting. Key electrical parameters include a maximum forward current of 50mA and a typical forward voltage of 1.65V. It operates within a temperature range of -55°C to +110°C and carries UL, C-UL, and VDE certifications.

Feature Summary

• Photovoltaic output architecture eliminates offset voltage drift over time
• High isolation voltage rating of 5000Vrms for robust signal transfer
• GaAs infrared LED source ensures long-term stability and reliability

Applications

• Precision analog signal isolation in measurement systems
• Zero-crossing detection circuits
• Solid-state relay driver interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix '300W' against the official datasheet to confirm packaging and reel specifications. Confirm component availability status as distribution data may indicate obsolete or limited stock conditions. Ensure compliance with RoHS directives and relevant safety standards required for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when zero-drift performance is critical, as the photovoltaic output lacks the saturation voltage issues found in transistor outputs. Consider the 5000Vrms isolation barrier for high-voltage noise immunity requirements. Evaluate the 4-pin DIP package constraints for PCB layout compatibility and thermal management needs within the specified operating temperature range.

Part Context

This part belongs to the FOD617 series from onsemi, specialized for high-reliability isolation tasks. Unlike standard transistor-output optocouplers, the photovoltaic design offers superior linearity and stability. The series is commonly used in industrial and medical applications where long-term signal integrity and high isolation voltage are mandatory specifications.

Replacement Considerations

Direct substitutes include the FOD617CS. Verify pinout compatibility and isolation voltage ratings when replacing. Note that the original part may be obsolete; check current manufacturing status and lead times for alternative sources.
