Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix FVM against the official onsemi datasheet to confirm the surface-mount package variant and lead configuration. Ensure compatibility with reflow soldering profiles defined in the manufacturer's thermal handling guidelines. Cross-reference the part number with the latest ordering information on the onsemi website, as Fairchild legacy designations may have undergone nomenclature updates during integration. Confirm availability status directly with authorized distributors, as production cycles vary.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. The presence of a base terminal allows for external biasing to reduce storage time, making it suitable for applications demanding faster switching than standard phototransistors. Verify that the 70 V collector-emitter voltage and 4170 Vrms isolation ratings meet the system's safety and operational voltage constraints. Consider the 6-SMD footprint dimensions during PCB layout planning.
