Single Diodes Procurement Notes
Verify the specific suffix and marking code against the official Diotec Semiconductor datasheet to confirm the exact variant. Ensure the ordering information matches the required packaging format and tape-and-reel specifications. Confirm that the component meets the specific temperature range and reliability requirements for the intended automotive application environment before finalizing procurement.
Single Diodes Selection Notes
Select this component when a compact SOD-123FL footprint is required for high-current automotive applications. The 40 V rating suits low-voltage DC bus systems. Compare thermal resistance characteristics against alternative packages if heat dissipation is critical. Verify compatibility with automated assembly processes given the small outline dimensions.
Single Diodes Part Context
This part belongs to Diotec's automotive-grade Schottky diode portfolio, designed for reliability in harsh environments. The 'AQ' suffix typically denotes AEC-Q101 qualification. It complements other series like the SMB and SMC packages for higher power handling needs within the same manufacturer lineup.
Single Diodes Replacement Considerations
Check for direct cross-reference part numbers from Diotec or other manufacturers offering identical 40V/3A SOD-123FL Schottky specifications. Ensure pinout compatibility and thermal performance match the original design requirements.
