Overview
The FOD817X_5699W is a single-channel transistor output optoisolator manufactured by onsemi. It features an NPN phototransistor output and provides 5000 Vrms insulation voltage. The device operates with a maximum forward current of 50 mA and a forward voltage of 1.4 V. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a collector-emitter saturation voltage of 200 mV. The unit exhibits rise and fall times of 18 µs each, with a reverse voltage rating of 6 V and power dissipation of 200 mW. It is housed in a PDIP-4 package.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Utilizes an NPN phototransistor for signal transmission
- Designed for through-hole mounting applications
Applications
- General-purpose digital signal isolation
- Microcontroller interface circuits
- Switching power supply feedback loops
Procurement Notes
Verify the specific CTR binning requirements against the official datasheet, as the X suffix indicates a particular current transfer ratio range distinct from standard variants. Confirm that the PDIP-4 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the system's environmental specifications before finalizing the component selection.
Selection Notes
Select this component when a standard transistor output optocoupler is required for basic isolation tasks. Compare the 5000 Vrms insulation rating against the system's safety standards. Evaluate the 18 µs switching speed to ensure it satisfies the application's timing constraints. Consider the PDIP-4 form factor for compatibility with existing through-hole assembly processes.
Part Context
This part belongs to the FOD817 family of optoisolators, which are widely used for general-purpose isolation. The FOD817 series is known for its reliability in transferring digital signals across isolated boundaries. The specific model integrates an infrared emitting diode with an NPN phototransistor to achieve galvanic isolation.
Replacement Considerations
Standard FOD817 variants may serve as functional substitutes if their CTR ranges overlap with the design requirements. Verify pinout compatibility and insulation voltage ratings before substitution.
