Single Zener Diodes Procurement Notes

Verify that the specific suffix 'Q' confirms AEC-Q101 automotive qualification status as indicated in official documentation. Ensure the DO-214AA footprint matches the target PCB design. Confirm RoHS3 compliance requirements align with project specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 220 V reference is required in a 3 W surface-mount configuration. The AEC-Q101 certification makes it suitable for automotive environments requiring extended temperature ranges. Consider the 1600 Ohm impedance limit for noise-sensitive applications where higher impedance may impact regulation precision.

Single Zener Diodes Part Context

This part belongs to the 3SMBJ series of Zener diodes from MCC, designed for robust voltage regulation. The 'Q' suffix typically denotes automotive-grade processing and testing. It shares the SMB package form factor with other high-power diodes in the lineup but is distinguished by its specific 220 V rating and automotive qualification.

Single Zener Diodes Replacement Considerations

Cross-reference with other 3W Zener diodes in the DO-214AA package having 220V nominal voltage. Verify if alternative parts meet the same AEC-Q101 qualification and 175°C operating temperature limits to ensure functional compatibility in existing designs.
