Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (36AE) against official Broadcom datasheets to confirm lead spacing and packaging details. Ensure compatibility with existing PCB footprints for PDIP-4 Gull Wing configurations. Cross-reference RoHS compliance status with current manufacturer declarations before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when 5000 Vrms isolation is required for single-channel applications. Consider the 18 µs switching speed for moderate-speed digital signals. Verify that the 50 mA collector current rating meets load requirements. Check thermal management needs given the 200 mW power dissipation limit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of optocouplers from Broadcom Limited. The series typically offers various isolation ratings and output types. The HCPL-817 variant specifically focuses on general-purpose isolation with transistor outputs, widely used in legacy and modern industrial designs requiring reliable signal transfer across potential differences.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes such as HCPL-817-36CE or other HCPL-817 variants with matching isolation and current ratings. Verify that any replacement maintains the same PDIP-4 package dimensions and electrical characteristics.
