Diode Arrays Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Comchip Technology or authorized distributors before procurement. Confirm that the SOT-323-3 package dimensions match your PCB footprint requirements. Ensure that the 30 V reverse voltage rating provides sufficient margin for your specific operating conditions and transient spikes. Cross-reference the part number suffix to confirm it matches the exact electrical characteristics required for your design.

Diode Arrays Selection Notes

Select this component when a low-profile, dual-series Schottky diode is required for space-constrained designs. The 200 mA current rating suits low-power applications where minimal forward voltage drop is critical for efficiency. Consider the 30 V reverse voltage limit to ensure compatibility with system rail voltages. The SOT-323-3 package offers a smaller footprint compared to standard single-diode packages, making it suitable for dense board layouts.

Diode Arrays Part Context

The CDBV3-54S-HF belongs to Comchip Technology's CDBV3 series of Schottky barrier rectifiers. This series utilizes silicon epitaxial planar technology to achieve fast switching speeds and low reverse recovery times. The dual series configuration allows two diodes to be integrated into a single small outline transistor package, reducing board space and assembly costs while maintaining high reliability and thermal performance.

Diode Arrays Replacement Considerations

Direct replacements must match the SOT-323-3 package, 30 V reverse voltage, 200 mA forward current, and dual series configuration. Verify pinout compatibility as internal connection schemes may vary between manufacturers. Ensure equivalent forward voltage and reverse leakage current specifications to maintain circuit performance.
