Overview
The FOD817300W is a single-channel phototransistor optocoupler from the FOD817 series, manufactured by Fairchild Semiconductor (now onsemi). It features a gallium arsenide infrared emitting diode coupled to a silicon phototransistor in a 4-pin MDIP package. Key electrical parameters include a maximum collector-emitter breakdown voltage of 70V and an isolation voltage of 5000Vrms. The device supports a maximum forward input current of 50mA with a typical rise/fall time of 18μs. It operates within a temperature range of -55°C to 110°C and carries C-UL, UL, and VDE certifications.
Feature Summary
- High operating temperature capability compared to standard counterparts
- Compact 4-pin dual in-line package design
- Compliant with Pb-free IR reflow soldering processes
Applications
- Power supply regulators
- Digital logic inputs
- Microprocessor inputs
Procurement Notes
Verify manufacturer status as Fairchild Semiconductor has been integrated into onsemi. Confirm part availability and obsolescence status through official channels. Ensure ordering suffixes match specific binning requirements for current transfer ratio. Check for updated nomenclature if replacing legacy Fairchild stock with onsemi equivalents.
Selection Notes
Select this component for applications requiring high isolation voltage and extended temperature operation. The FOD817D bin provides a current transfer ratio range of 300% to 600%, suitable for robust signal transmission. Ensure circuit design accommodates the 70V minimum collector-emitter breakdown voltage. Verify compatibility with surface mount form factors if required.
Part Context
This component belongs to the FOD817 series of 4-pin phototransistor optocouplers. The series includes variants like FOD817A, B, C, and D, differentiated primarily by their current transfer ratio bins. The '300W' suffix typically denotes specific packaging or binning characteristics within the Fairchild/onsemi portfolio.
Replacement Considerations
Legacy Fairchild parts may require substitution with onsemi equivalents due to corporate integration. Verify that the replacement part number reflects the updated naming convention without underscores.
