Feature Summary

• High Q hyperabrupt characteristic optimized for low tuning voltage applications
• Qualified according to AEC-Q101 automotive standards
• Pb-free construction compliant with RoHS directives

Applications

• Voltage Controlled Oscillators (VCOs) in mobile communications equipment

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and marking code. Ensure compliance with environmental regulations regarding lead-free materials. Check for any discontinuation notices or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high Q factors and hyperabrupt capacitance-voltage characteristics. The SOD-323 package suits compact surface-mount designs. Verify that the 7 V reverse voltage limit accommodates the circuit's peak reverse bias conditions. Consider the -55 °C to 125 °C operating range for environmental suitability.

Part Context

This part belongs to the BBY51 series of silicon tuning diodes. Variants such as BBY51-02L and BBY51-02W offer different package configurations like TSLP-2-1 or SC80 while maintaining similar electrical profiles. The '03W' suffix specifically denotes the SOD-323 package variant with corresponding laser marking codes.

Replacement Considerations

Direct substitutes include other BBY51 series variants like BBY51-02L or BBY51-02W if package compatibility allows. Cross-reference capacitance ratios and reverse voltage ratings with alternative hyperabrupt tuning diodes from other manufacturers to ensure functional equivalence in VCO designs.
