Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify specific ordering suffixes (e.g., -000E, -020E) to confirm insulation voltage ratings and packaging types. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by variant. Ensure the selected package matches the intended PCB assembly method, whether through-hole or surface mount.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select variants based on required isolation voltage levels, choosing between standard 3750 Vrms or enhanced 5000 Vrms options. Consider package type preferences, such as PDIP for through-hole or SOIC-8 for space-constrained surface-mount designs. Verify that the 100 kb/s data rate meets system timing requirements and that the 60 mA output current capability suffices for load driving needs.
