Single Diodes Procurement Notes

Verify the specific datasheet revision and AEC-Q101 certification status directly with Comchip Technology or authorized distributors before integration. Confirm that the SOD-923F footprint matches the target PCB design. Ensure supply chain sources are authorized to guarantee component authenticity and traceability for automotive compliance requirements.

Single Diodes Selection Notes

Select this component when a small-form-factor Schottky diode is required for automotive environments. The 70 V rating suits low-voltage DC bus protection. Consider the 70 mA current limit for signal-level or low-power rectification tasks. The wide operating temperature range supports harsh automotive conditions. Verify thermal management needs against the small package dissipation capabilities.
