Overview
The FOD817ASD_F117 is a single-channel phototransistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode coupled to a silicon NPN phototransistor within a surface-mount SMD-4 package. The device provides an isolation voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 70 V with a peak forward current of 50 mA. Typical switching characteristics include rise and fall times of 18 µs, while the power dissipation rating is 200 mW. Operating temperatures range from -55°C to +110°C.
Feature Summary
- Integrates a gallium arsenide infrared LED with a silicon phototransistor for signal transmission
- Provides high electrical isolation capability rated at 5000 Vrms
- Designed for surface-mount assembly in compact four-pin configurations
Applications
- General-purpose digital signal isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact binning or packaging variations. Ensure the component meets required safety certifications such as UL or VDE if applicable to the end equipment. Cross-reference the datasheet revision history to validate performance parameters before finalizing procurement specifications.
Selection Notes
Select this component when surface-mount technology is required for single-channel isolation applications. Consider the 18 µs switching speed and 5000 Vrms isolation rating for general-purpose use cases. Evaluate thermal management requirements given the 200 mW power dissipation limit and ensure the operating temperature range aligns with system constraints.
Part Context
This part belongs to the FOD817 series of transistor-output optocouplers produced by onsemi. The series is widely utilized for providing electrical isolation between low-voltage control circuits and higher-voltage loads. The ASD variant specifically denotes a surface-mount form factor, distinguishing it from through-hole DIP equivalents within the same functional family.
Replacement Considerations
Compatible substitutes include other FOD817 series variants such as FOD817A, FOD817B, or FOD817C, provided the package type and current transfer ratio specifications match the design requirements.
