Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. The E3 suffix indicates RoHS compliance and industrial grade classification. Confirm that the package code matches the required reel diameter and base quantity for automated placement processes. Ensure technical parameters are validated for the intended application environment before procurement.

Single Zener Diodes Selection Notes

Select this component based on the required nominal Zener voltage and power dissipation capabilities. Consider the operating temperature range and the maximum steady-state power dissipation limits when designing thermal management solutions. Verify that the package dimensions align with the PCB layout constraints and automated placement equipment specifications.

Single Zener Diodes Part Context

This part belongs to the SMZG3788B through SMZG3809B series of surface-mount power voltage-regulating diodes. The series utilizes the SMBG (DO-215AA) case configuration and offers a wide range of Zener voltages from 9.1 V to 68 V. These devices are designed for high-reliability applications requiring low profile packaging and robust electrical performance.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other SMZG38xxB variants with different Zener voltages. Cross-series replacements must match the DO-215AA package outline and maintain equivalent power dissipation ratings. Verify that alternative components meet the same AEC-Q101 qualification and RoHS compliance standards.
