Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with automated pick-and-place equipment regarding the SOD-923F-2 footprint dimensions. Confirm RoHS compliance status matches project environmental standards before finalizing procurement orders.

Selection Notes

Select this component when board real estate is constrained due to its ultra-thin form factor. Consider the 100 mA current rating for suitability in low-power signal rectification or small-signal power paths. Evaluate thermal management needs based on the package's dissipation capabilities relative to the expected operating temperature range.

Part Context

This part belongs to the CDBQC series of Schottky Barrier Rectifiers from Comchip Technology. The series emphasizes batch process design for consistent thermal resistance and reverse leakage current performance. It targets modern electronics demanding miniaturization without compromising switching speed or power efficiency.

Replacement Considerations

Direct substitutes must match the 100 mA current, 30 V voltage rating, and SOD-923F-2 package. Verify pinout polarity and forward voltage specifications to ensure circuit functionality remains unchanged during replacement.
