Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape-and-reel quantities. Confirm that the component meets the required AEC-Q101 qualification level for your target application. Check RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a low-voltage Zener reference is required in space-constrained automotive environments. The UMD2 package offers a small footprint ideal for high-density PCB layouts. Ensure the 200 mW power rating and 2 V breakdown voltage align with the circuit's operational requirements and thermal management capabilities.

Single Zener Diodes Part Context

This part belongs to Rohm's UDZVFH series of Zener diodes, which are specifically engineered for automotive applications. The series emphasizes miniaturization and robustness, utilizing the SC-90A (SOD-323FL) package standard. These components are designed to replace older through-hole or larger surface-mount alternatives in modern vehicle electronics.

Single Zener Diodes Replacement Considerations

Direct pin-compatible substitutes within the same family include other variants in the UDZVFHTE series with different voltage ratings. Verify that any replacement maintains the same UMD2 package dimensions and AEC-Q101 certification to ensure mechanical and reliability compatibility.
