Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific CTR bin (X3) corresponds to the required gain range of 50% to 600% for your design. Confirm the DIP-4 package compatibility with your PCB footprint. Ensure the 5000 Vrms isolation rating meets safety standards for your application. Check RoHS compliance documentation if environmental regulations apply. Validate that the 20 mA collector current limit is sufficient for the load.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard single-channel isolation solution with moderate speed is required. The X3 designation indicates a specific Current Transfer Ratio range suitable for logic-level switching. Compare against other PC817 variants if different CTR bins or package types are needed. Consider the 18 µs switching time for frequency limitations. Ensure the 80 V collector-emitter voltage exceeds the peak voltage in the switched circuit.
