Procurement Notes

Verify the specific part number against the manufacturer's datasheet to confirm electrical ratings and package dimensions. Ensure compliance with RoHS requirements as indicated in the product documentation. Check for any recent design updates or reliability improvements issued by Comchip Technology prior to finalizing procurement specifications.

Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency in surface-mount designs. The DO-214AC package offers a compact footprint suitable for automated assembly processes. Consider the thermal resistance and current derating curves if operating in high ambient temperature environments to ensure reliable performance within the specified junction temperature limits.

Part Context

The CDBA220L-G belongs to the CDBA220L-G through CDBA240LL-G series of Low VF SMD Schottky Barrier Rectifiers produced by Comchip Technology. This series provides various reverse voltage options ranging from 20 V to 40 V while maintaining a consistent 2.0 A forward current rating. The devices are designed for high-reliability applications requiring efficient power conversion in small form factors.

Replacement Considerations

Compatible substitutes within the same series include CDBA220LL-G, which shares identical electrical characteristics but may differ in specific manufacturing revisions. Verify pinout compatibility and package dimensions when replacing with other SMA-packaged Schottky diodes from different manufacturers.
