Single Zener Diodes Procurement Notes

Verify supply status carefully as this component may be subject to Last Time Buy notices. Confirm that the ordering part number VDZFHT2R5.1B matches the required specification. Ensure compatibility with existing PCB footprints for the VMD2 package. Check for recommended replacement parts if long-term availability is a concern.

Single Zener Diodes Selection Notes

Select this component when an AEC-Q101 qualified Zener diode is required in a small SOD-723 package. Consider the 100mW power dissipation limit and 5.1V nominal voltage. Evaluate the EDZVFH5.1B as a potential alternative with similar specifications but different packaging if space or supply constraints exist.

Single Zener Diodes Part Context

This part belongs to the VDZFH series of Zener diodes manufactured by ROHM Semiconductor. The series is characterized by its compliance with automotive quality standards and its use in compact surface-mount packages. The VDZFHT2R5.1B specifically denotes the tape-and-reel version of the 5.1V variant in the VMD2 package.

Single Zener Diodes Replacement Considerations

The EDZVFHT2R5.1B is listed as a recommended replacement with similar specifications. Note that it uses an EMD2 (SOD-523) package, which differs in physical dimensions from the VMD2 package of the original part.
