Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix W6CE against official Broadcom documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure the component meets all relevant safety certifications required for your final equipment design.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel with 5000 Vrms isolation and 50mA output current capability is required. Consider the 70V collector-emitter voltage rating for higher voltage load interfaces compared to lower-rated variants. Evaluate the 18us rise/fall times against system speed requirements before choosing over faster logic-output alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-817 series of transistor output optocouplers from Broadcom. The series is widely used for general-purpose isolation tasks. The W6CE suffix typically denotes specific packaging and reel configurations within the broader product family, distinguishing it from tube-packaged equivalents like the HCPL-817-00BE.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same series include HCPL-817-00BE and HCPL-817-500E, though pinout and packaging may differ. Verify functional equivalence regarding CTR ranges and isolation ratings before substitution.
