Single Zener Diodes Procurement Notes

Verify that the ordering suffix LT1G corresponds to the specific tape and reel packaging configuration required for your manufacturing line. Confirm that the SZ prefix meets all automotive quality management system requirements, including PPAP submission, if the component is intended for use in automotive assemblies or other applications demanding strict site control changes.

Single Zener Diodes Selection Notes

Select this component when a low-profile surface-mount solution is required for voltage regulation in space-constrained designs. The tight tolerance series availability allows for precise voltage referencing. Ensure the application environment stays within the specified thermal limits and that the 250 mW power rating on FR-4 or FR-5 substrates aligns with the circuit's thermal dissipation capabilities.

Single Zener Diodes Part Context

This part belongs to the BZX84CxxxLT1G series of Zener diodes offered by onsemi. The series covers a wide breakdown voltage range from 2.4 V to 75 V, providing designers with flexible options for various reference and regulation needs while maintaining consistent mechanical and electrical performance standards across the product family.

Single Zener Diodes Replacement Considerations

Non-SZ prefixed equivalents such as BZX84C2V7LT1G share identical electrical specifications but lack the specific automotive qualification and PPAP documentation associated with the SZ prefix. Verify site-specific requirements before substituting.
