Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '560E' confirms the gull-wing surface mount package variant, distinct from through-hole DIP versions. Confirm RoHS compliance status via the official datasheet. Check lifecycle status as some distributors list this part as obsolete or limited supply. Ensure the manufacturer is identified as Broadcom Limited or Avago for authenticity.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high gain and moderate speed are required for galvanic isolation. The photodarlington output offers higher current drive than standard transistor outputs but may have slower switching speeds compared to logic gate outputs. Verify that the 100 kb/s data rate meets system timing requirements and that the 3750 Vrms isolation voltage satisfies safety standards.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL series of optocouplers from Broadcom Limited. The series includes various packages and output types, such as transistors, darlingtons, and logic gates. The HCPL-4701 specifically denotes the single-channel photodarlington variant, designed for applications requiring high current transfer ratios and reliable signal transmission across isolated boundaries.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-4701-500E is a documented substitute part number, representing the same functional device but packaged in an 8-pin DIP format rather than the gull-wing SMD package of the 560E variant. Verify pinout compatibility and mounting constraints before substitution.
