Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix DE against official Broadcom datasheets to confirm package type and tape/reel specifications. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm that the delivered units match the exact electrical parameters listed in the official specification sheet.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and moderate speed are required. Compare the 70 V collector-emitter voltage against system requirements. Evaluate the 4 µs rise time against signal integrity needs. Consider the PDIP-4 or surface mount package availability depending on assembly constraints. Verify thermal management capabilities for the specified power dissipation limits.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL series of transistor output optocouplers from Broadcom Limited. The series is designed for general-purpose isolation applications. The HCPL-817 variant specifically targets cost-effective solutions with reliable performance. It shares core architectural similarities with other members of the family while differing in packaging and specific electrical tolerances defined by the suffix.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Official substitutes may include other HCPL-817 variants such as HCPL-817-36CE or HCPL-817-30AE if pin compatibility and electrical ratings align.
