Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., CV, CR2V) against the required packaging format, such as tube or reel, as these affect logistics but not function. Confirm RoHS compliance status via official manufacturer declarations. Ensure the ordering part number matches the exact current transfer ratio grade needed for the design. Cross-reference datasheet revisions to confirm pinout and thermal characteristics remain consistent with previous versions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel transistor output is required for moderate-speed signal isolation. The FODM217C offers a balance of speed and gain suitable for general industrial applications. Consider the C-grade current transfer ratio if higher gain is not strictly necessary. Verify that the SOP-4 package dimensions fit the available PCB space. Compare against other FODM217 variants if different packaging or CTR grades are preferred.

Transistor, Photovoltaic Output Optoisolators Part Context

The FODM217C belongs to the FODM217 series of transistor output optocouplers from onsemi. This series includes variants with different current transfer ratios and packaging options, such as the FODM217A, B, D, and their respective reel or tube suffixes. All members share the same core electrical architecture and isolation capabilities, differing primarily in gain specifications and supply configuration.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include FODM217CV and FODM217CR2V. These parts share identical electrical specifications and pinouts but differ in packaging type. Verify that any replacement maintains the required 3750 Vrms isolation and 80 V collector-emitter voltage ratings.
