Single Zener Diodes Selection Notes

Select this component when a 43 V reference requires tight ±2% accuracy and robust thermal stability. The SOD-80C package suits space-constrained designs needing high-temperature resilience. Ensure the circuit current remains within the 500 mW dissipation limit and verify that the 150 Ohm impedance meets noise sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the BZV55 series of low-power voltage regulator diodes. The series provides a comprehensive range of normalized E24 voltages from 2.4 V to 75 V. The 'B' designation indicates the ±2% tolerance variant, distinguishing it from the standard ±5% 'C' series variants within the same LLDS package family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' SOD-80C Zener diodes rated at 43 V with ±2% tolerance and 500 mW power dissipation. Verify pinout compatibility and thermal characteristics before substitution.
