Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix W6DE against official Broadcom datasheets to confirm pinout and packaging details. Confirm RoHS compliance status as indicated in the latest manufacturer documentation. Ensure the component meets the required operating temperature range of -30°C to +100°C for your specific application environment before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of isolation with moderate speed (18 µs) is sufficient. The 70 V collector-emitter voltage rating supports common logic-level interfaces. Consider the 50 mA collector current limit for load driving capabilities. Verify that the PDIP-4 package fits the available board space and that the thermal dissipation requirements are met within the specified ambient temperature limits.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-817 series of transistor output optocouplers from Broadcom Limited. The series is designed for general-purpose isolation applications where cost-effective, reliable signal transfer across potential barriers is required. The W6DE suffix typically denotes specific packaging or tape-and-reel configurations compared to other variants in the family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Consult official Broadcom substitution guides for verified equivalents. Generic replacements must match the 5000 Vrms isolation rating, 70 V Vceo, and 50 mA Ico specifications. Verify pin compatibility and switching time characteristics to ensure circuit functionality remains unchanged.
