Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and lead condition upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit products. Validate technical specifications match design requirements before final procurement.

Single Zener Diodes Selection Notes

Select this component when an 18 V Zener reference is required in a compact through-hole format. Consider the 500 mW power rating for thermal management in enclosed designs. Evaluate the DO-35 package dimensions for PCB layout constraints. Compare leakage and impedance specs against alternative series if tighter tolerances are needed.

Single Zener Diodes Part Context

This component belongs to the standard 1N52xx series of 500 mW Zener diodes manufactured by onsemi. The series offers a broad range of voltage options in the DO-35 package. The 'B' suffix typically denotes a 5% tolerance variant. This specific model provides a mid-range voltage option within the series lineup.
