FOD617BW

Overview

The FOD617BW is a single-channel phototransistor output optocoupler manufactured by onsemi. It features a 4-pin DIP package with an isolation voltage of 5000Vrms. The device supports a maximum forward current of 50mA and a collector-emitter saturation voltage of 400mV. Typical rise and fall times are 18μs, with a collector-emitter breakdown voltage of 70V. Operating temperatures range from -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a phototransistor output for signal transmission
• Designed for through-hole mounting in standard DIP packages

Applications

• General-purpose signal isolation
• Industrial control systems
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'BW' against official datasheets to confirm pinout and packaging details. Ensure compatibility with existing board layouts requiring 4-pin DIP configurations. Confirm that the 5000Vrms isolation rating meets safety standards for the target application environment.

Selection Notes

Select this component when high isolation voltage is required in a low-speed application. The 18μs switching speed limits use cases compared to faster logic gate outputs. Verify that the 50mA collector current capability aligns with downstream circuit requirements.

Part Context

This part belongs to the FOD617 series of transistor output optocouplers. It shares functional similarities with other members like the FOD617D but may differ in specific packaging or testing parameters. The series is designed for general-purpose isolation tasks.

Replacement Considerations

Direct substitutes include FOD617D and FOD617B. Verify pin compatibility and electrical specifications before substitution.
