Single Zener Diodes Procurement Notes

Verify the specific suffix 'BK' indicates bulk packaging when ordering. Confirm that the 'PBFREE' designation aligns with environmental compliance requirements for the target assembly process. Ensure the DO-35 axial form factor matches the printed circuit board layout constraints. Cross-reference the manufacturer's latest product discontinuation notices to confirm active production status before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a precise 14 V reference is required with tight ±5% tolerance. The DO-35 package suits designs needing axial leads for through-hole mounting. Evaluate the 500 mW power dissipation limit against expected thermal loads in the final enclosure. Consider the low reverse leakage current for sensitive analog signal conditioning paths where minimal current drain is critical.
