Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BG' against official Isocom documentation to confirm exact binning or testing criteria, as suffixes may denote variations in CTR ranges or packaging not always detailed in general summaries. Ensure the PDIP package type matches the target PCB footprint. Cross-reference the 5300 Vrms isolation rating with system safety requirements. Confirm compliance with relevant standards such as UL if required for the end application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel optocoupler with NPN output is required for digital isolation. The 5300 Vrms isolation rating suits applications demanding high safety margins. Consider the 50 mA maximum forward current limit for drive circuit design. The PDIP package is suitable for through-hole mounting. Verify that the 200% minimum CTR meets the switching speed and load requirements of the destination circuit.
