Procurement Notes

Verify the specific manufacturer source, as multiple vendors produce this standard part number. Confirm package type (DO-7 vs DO-35) matches design requirements. Check RoHS compliance status if restricted materials are prohibited. Ensure operating temperature ratings align with environmental conditions. Validate datasheet revisions for accurate electrical parameters before finalizing procurement.

Selection Notes

Select this component when an 8.2 V Zener reference is required with 500 mW power capability. Consider the axial leaded package for through-hole mounting constraints. Evaluate thermal management needs given the power dissipation rating. Compare leakage current specifications against sensitive circuit requirements. Verify availability from authorized distributors to ensure supply chain reliability.
