Note that availability may be limited as the part status is listed as obsolete in some regions; ensure alternative sourcing strategies are in place for production continuity.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and base-controlled output are required in a compact surface-mount form factor. Ensure the application environment stays within the specified operating temperature range. Verify that the input current requirements do not exceed the 100 mA limit and that the load can be driven by the NPN phototransistor output characteristics.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to onsemi's family of transistor output optocouplers. It shares similar packaging and basic functionality with models like the CNX39U3SD, though specific current transfer ratios and performance metrics may vary. These devices are typically used in applications demanding reliable electrical isolation between low-voltage control circuits and higher-voltage power stages.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct substitutes such as the CNX39U3SD from the same manufacturer, noting differences in current transfer ratio. Evaluate other single-channel SMD-DIP-6 optocouplers with comparable 5300 Vrms isolation and NPN phototransistor outputs if exact matches are unavailable.
