FOD817C300

Overview

The FOD817C300 is a single-channel, through-hole phototransistor optocoupler from the FOD series by onsemi. It features a 4-pin MDIP package with DC input and NPN phototransistor output. Key electrical parameters include an isolation voltage of 5000Vrms, a forward current of 50mA, and a maximum collector-emitter voltage of 70V. The device operates within a temperature range of -55°C to +110°C, with typical rise and fall times of 18μs. Current transfer ratio ranges from 200% to 400%, and it supports UL and VDE certifications.

Feature Summary

Provides high-voltage isolation between input and output circuits using optical coupling technology.
Features a standard 4-pin DIP package suitable for through-hole mounting applications.
Delivers reliable signal transmission with defined current transfer ratios for digital switching.

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix '300' against official datasheets to confirm packaging type and regional compliance standards. Ensure the procurement source provides valid RoHS documentation and original manufacturer traceability. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the received units match the active status indicated in public component databases.

Selection Notes

Select this component when a robust, general-purpose optocoupler with high isolation voltage is required for through-hole designs. Consider the 50mA collector current limit and 70V breakdown voltage for circuit compatibility. Evaluate the 18μs switching speed against application timing requirements. Compare against other FOD817 variants if different CTR grades or packaging options are needed.

Part Context

This component belongs to the FOD817 family of 4-pin DIP phototransistor optocouplers manufactured by onsemi. The family is widely used in industrial and consumer electronics for basic signal isolation. The FOD817C300 specifically denotes a particular binning of current transfer ratio and packaging configuration within this established product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Verify pinout compatibility and electrical specifications before considering alternative manufacturers.
