Overview
The FOD617AW is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and provides 5000 Vrms insulation voltage. The device operates with a maximum collector-emitter voltage of 70 V and a forward current of 50 mA. Key electrical parameters include a forward voltage of 1.65 V, a maximum collector current of 50 mA, and a power dissipation of 200 mW. The unit weight is 260 mg.
Feature Summary
- Provides high-voltage isolation capability for signal transmission between isolated circuits.
- Utilizes an NPN phototransistor output configuration for switching applications.
- Designed for robust performance across extended industrial temperature ranges.
Applications
- General-purpose signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix 'AW' against the official datasheet to confirm package dimensions and tape/reel specifications if applicable. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the component meets all environmental operating limits defined in the specification sheet before integration into final assemblies.
Selection Notes
Select this component when 5000 Vrms isolation is required with a standard NPN phototransistor output. Compare rise and fall times against system speed requirements. Verify that the 70 V collector-emitter voltage rating exceeds the load voltage in the target application circuit to ensure reliable operation under all conditions.
Part Context
This part belongs to the FOD617 series of transistor output optocouplers from onsemi. It shares functional similarities with other DIP-4 packaged isolators but is distinguished by its specific 5kV isolation rating and NPN output characteristics. The series is commonly used in legacy and modern designs requiring galvanic isolation.
Replacement Considerations
Check for direct pin-compatible alternatives such as the FOD617D or FOD817B. Verify that substitute parts match the 5000 Vrms isolation voltage and NPN output type. Ensure the replacement maintains compatibility with the existing PCB footprint and thermal management requirements.
