Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix X001 against official Vishay documentation to confirm package type and CTR binning. Ensure compatibility with required isolation standards such as UL or IEC if applicable. Confirm that the 5000 Vrms rating meets system safety requirements. Check for availability of RoHS compliance data relevant to the manufacturing date code.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a base-connected phototransistor is required for faster switching or improved linearity compared to unconnected base variants. Consider the 160-320% CTR range for consistent gain in digital switching applications. Evaluate the 70V collector voltage limit against load requirements. Compare thermal dissipation capabilities if operating near the upper temperature limit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of general-purpose optocouplers. The series offers various CTR bins and packaging options, including surface mount and through-hole configurations. The CNY17-4 variant specifically targets applications requiring higher current transfer ratios than lower-bin parts like the CNY17-1.
