Single Zener Diodes Procurement Notes

Verify the specific suffix BGWX against official Nexperia documentation to confirm pinout and tolerance specifications. Ensure the procurement channel provides traceable datasheets matching the SOD-123-2 package dimensions. Confirm RoHS compliance status directly with the supplier or manufacturer records prior to integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V reference with 2% accuracy is required in a compact footprint. Consider the 625 mW power rating for thermal management in enclosed environments. The wide temperature range makes it suitable for automotive or industrial settings where standard commercial grade parts may fail. Compare leakage current specs against other series if ultra-low bias is critical.
