Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode with a nominal 39 V breakdown voltage is required. The ±5% tolerance variant suits applications where standard precision is adequate. Ensure the design accommodates the 300 mW power dissipation limit and the thermal characteristics associated with the small SOD523 footprint.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX585 series of voltage regulator diodes. The series comprises 74 types covering nominal voltages from 2.4 V to 75 V. These diodes are designed for general-purpose regulation tasks and are available in two tolerance series: ±2% (BZX585-B) and ±5% (BZX585-C).

Single Zener Diodes Replacement Considerations

Cross-reference with other BZX585-C39 variants or equivalent SOD523 Zener diodes from other manufacturers if supply constraints exist. Verify that replacement parts match the 39 V nominal voltage, ±5% tolerance, and 300 mW power rating specifications.
