Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the surface-mount tape-and-reel packaging format. Ensure the component matches the required 8-pin SMD PDIP footprint dimensions for PCB layout compatibility. Confirm that the manufacturer designation aligns with Isocom Components specifications rather than generic equivalents.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel optocoupler with moderate speed characteristics is required. The 5.3kVrms isolation rating suits applications demanding robust noise immunity. Consider the 50mA input current limit and the specific current transfer ratio range for driving subsequent stages effectively within the specified temperature limits.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISD series of optocouplers, which are characterized by their dual-channel or single-channel configurations depending on the specific model variant. The ISD74 variant specifically denotes a single-channel device with transistor output, distinct from other series members that may offer different output types or pin counts.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the 8-pin SMD PDIP package and 5.3kVrms isolation rating. Verify equivalent current transfer ratios and switching times. Cross-reference with other manufacturers offering similar single-channel transistor output optocouplers in compatible surface-mount packages.
