Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix W0LE against official Broadcom documentation to confirm the exact current transfer ratio and packaging specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Check for end-of-life notifications or obsolescence warnings directly from authorized distributors before procurement planning.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel isolation barrier with moderate speed and high voltage ratings is required. Ensure the circuit design accommodates the 35 V collector-emitter voltage limit and 50 mA maximum current. Verify that the PDIP-4 package style matches the PCB layout constraints and thermal management requirements of the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-817 series of transistor output optocouplers. The series offers various configurations distinguished by suffixes indicating current transfer ratio ranges and packaging types. The HCPL-817-W0LE specifically denotes a version with a 100% current transfer ratio packaged in a tube format, distinct from surface-mount variants like the HCPL-817-500E.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include HCPL-817-W0BE and HCPL-817-W0CE, which share identical electrical parameters but differ in current transfer ratio specifications. Cross-reference these part numbers against official Broadcom substitution lists to ensure functional compatibility.
