Procurement Notes

Verify the specific suffix WCRZ to confirm the wide-temperature and automotive-qualified variant. Confirm package type matches SOIC-8 specifications. Check RoHS compliance status against current regulatory requirements. Ensure availability aligns with restricted supply conditions noted by distributors. Validate that the reel packaging quantity meets production needs.

Selection Notes

Select this component when bidirectional communication is required at speeds up to 100 Mb/s. Choose this part over unidirectional variants if signal directionality must be reversible. Consider the AEC-Q100 qualification for applications subject to automotive standards. Verify that the 3000 Vrms insulation rating satisfies system safety isolation requirements.

Part Context

This component belongs to the ADUM1285 series of dual-channel digital isolators. It shares the SOIC-8 footprint with other members but differs in channel directionality and speed capabilities. The series utilizes capacitive or magnetic coupling technologies depending on the specific model number prefix.

Replacement Considerations

Direct replacements include other ADUM1285 series variants such as ADUM1285BRZ or ADUM1285ARZ, provided they meet the bidirectional and speed requirements. Verify pinout compatibility and insulation ratings before substitution.
