Procurement Notes

Verify the specific suffix H indicates the default high output configuration against the official Wurth Elektronik datasheet. Confirm the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for AEC-Q100 or similar reliability certifications if required for your specific application environment.

Selection Notes

Select this component when high-speed digital isolation is required for CAN or similar bus protocols. The 150 Mbps rate suits most standard industrial communication needs. Consider the 3750 Vrms isolation rating for safety compliance. The default high output feature simplifies interface design by ensuring a known state upon power-up. Evaluate the SOIC-8 package size against available board space constraints.
