Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm compliance with RoHS directives and ensure the component meets specific thermal dissipation requirements during installation. Cross-reference datasheet revision 19 for accurate electrical specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference is required with a 5 W power rating. Ensure the application circuit can handle the specified 150 mA test current and 580 mA maximum regulator current. Verify that the axial lead mounting position aligns with the PCB layout constraints and that ambient temperature conditions do not exceed the derating limits defined in the datasheet.
