Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix W00E to confirm through-hole packaging and RoHS compliance status. Confirm that the 35 V collector-emitter rating meets system requirements, as other variants may differ. Ensure the AC input capability aligns with the application design. Cross-reference datasheet revisions for any parameter updates before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when direct AC input drive is required without external rectification. The inverse parallel LED structure simplifies circuit design for AC signals. Verify that the 35 V output voltage rating is sufficient for the load. Consider the 18 us switching speed if timing constraints exist. Compare power dissipation limits against thermal management capabilities in the target enclosure.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-814 series of optocouplers designed for AC input applications. Unlike standard DC-coupled optocouplers, this series integrates two LEDs in inverse parallel to handle alternating current directly. It is distinct from the HCPL-817 series, which typically supports higher collector-emitter voltages but lacks the dedicated AC input optimization.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HCPL-814-000E shares similar functional characteristics but may differ in packaging or compliance status. Verify pinout compatibility and electrical ratings before substitution. Other HCPL-814 variants may offer different CTR ranges or voltage ratings.
