Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'W' corresponds to the 8-MDIP package variant when sourcing. Confirm that the component status is obsolete as indicated by manufacturer records, ensuring substitute availability is secured prior to procurement. Check datasheet revisions for any changes in mechanical dimensions or electrical limits compared to earlier production batches.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-accessed phototransistor outputs are required for faster switching than standard variants. Ensure the circuit design accommodates the 16 mA forward current requirement and the 8 mA maximum collector current limit. Verify that the 2500Vrms isolation rating meets the safety requirements of the application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

The HCPL4502W belongs to the HCPL-4500 series of high-speed optocouplers from onsemi. This series is characterized by its use of advanced LED technology and phototransistor outputs designed for rapid signal transmission. The 'W' suffix typically denotes the specific plastic DIP packaging configuration used in this product line.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitutes include the HCPL-4562 from Broadcom Limited. Verify pin compatibility and electrical specifications before substitution due to potential differences in current transfer ratios and switching speeds.
