Procurement Notes

Verify the specific ordering code against official Rohm Semiconductor documentation to ensure correct voltage tolerance and package variant. Confirm that the SOD-323 footprint matches your design constraints. Check for any suffix variations that may indicate different tape-and-reel quantities or lead-free specifications. Ensure compatibility with your assembly process requirements regarding moisture sensitivity levels.

Selection Notes

Select this component when a 6.2V reference point is needed in a small form factor. Evaluate the power dissipation capabilities relative to your circuit's maximum current draw. Consider the thermal resistance of the SOD-323 package if operating near maximum ratings. Compare leakage current specifications against your application's precision requirements to ensure adequate performance margins.
