Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix DFGR against the manufacturer's official datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure compliance with AEC-Q100 requirements if automotive qualification is needed, as this variant may differ from standard industrial grades. Cross-reference RoHS status and humidity sensitivity levels prior to procurement to align with assembly process constraints.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current transfer ratio and AC input compatibility are required in a compact SOIC-4 footprint. Compare CTR ranges and isolation voltages against alternative models like ISOM8117 or ISOM8116DFSR to ensure adequate margin for specific load conditions. Consider thermal dissipation limits and operating temperature range relative to the target application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISOM8116 series of AC-input optocouplers designed for robust isolation in noisy environments. It complements other variants such as ISOM8116DFSR and ISOM8116DFHRQ1, differing primarily in packaging, CTR specifications, and automotive qualification status within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations
