Single Zener Diodes Procurement Notes

Verify the complete part number including the suffix to confirm packing quantity and carrier type. Confirm that the component meets RoHS 3 and halogen-free requirements for your specific manufacturing standards. Ensure compatibility with IATF16949:2016 certified facility sourcing if automotive grade compliance is required for the project.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage with strict ±2.0% tolerance is necessary. Consider the 350 mW power dissipation limit and the SOD523 footprint constraints during PCB layout. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Single Zener Diodes Part Context

This component belongs to the BZT585B series of surface mount precision Zener diodes. The series covers a wide voltage range from 2.4 V to 43 V, all sharing the same compact SOD523 package and high-reliability automotive qualification standards. The 'TQ' designation indicates the specific tape and reel packaging configuration available for automated assembly processes.

Single Zener Diodes Replacement Considerations

Other parts in the BZT585B series offer different voltage ratings but share identical package dimensions and electrical profiles. Cross-reference datasheets for specific voltage tolerances and impedance values before substituting.
