FOD617B300W

Overview

The onsemi FOD617B300W is a single-channel phototransistor optocoupler in a DIP package. It features a maximum collector-emitter voltage of 400V and a typical current transfer ratio of 125%. The device supports a maximum forward input current of 50mA with a forward voltage of 1.4V. Key electrical parameters include a collector-emitter saturation voltage of 400mV, an isolation voltage of 5000Vrms, and operating temperatures ranging from -55°C to 110°C.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between circuits
• Utilizes a phototransistor output configuration for DC sensing applications
• Designed for through-hole mounting in standard DIP packages

Applications

• High-voltage switching circuits
• DC sensing interfaces
• Signal isolation in industrial control systems

Procurement Notes

Verify the specific suffix '300W' against official datasheets to confirm packaging details and exact electrical tolerances. Ensure compatibility with required isolation standards such as UL or VDE before integration. Cross-reference pinouts and thermal characteristics with the target PCB layout specifications.

Selection Notes

Select this component when high collector-emitter voltage ratings are required compared to standard 80V optocouplers. The 125% CTR offers moderate gain for general-purpose isolation. Consider the DIP package constraints and thermal management requirements for the intended operating environment.

Part Context

This part belongs to the FOD617 series, designed for general-purpose isolation. It differs from the FOD817 series by offering significantly higher collector-emitter voltage ratings. The device serves as a robust interface solution for applications requiring reliable signal transfer across high potential differences.

Replacement Considerations

FOD617B300: Standard tube packaging variant with identical electrical characteristics. Verify that the replacement matches the required reel quantity if tape-and-reel processing is necessary.
