Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' against official ROHM documentation to confirm exact voltage tolerance and testing parameters. Ensure compatibility with SOD-323FL footprint requirements during PCB layout. Confirm RoHS compliance status through current datasheets as specifications may evolve. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference is required in space-constrained automotive or industrial designs. The 500 mW power rating allows for moderate current handling in small packages. Consider the 20 mA test current for biasing requirements. Evaluate thermal management needs given the 150 °C junction temperature limit.

Single Zener Diodes Part Context

This part belongs to ROHM's UFZVTE series of Zener diodes, which are engineered for high-reliability applications. The series utilizes advanced semiconductor processing to achieve tight voltage tolerances and low leakage currents. These components are widely used in automotive electronics where long-term stability and robustness are critical.

Single Zener Diodes Replacement Considerations

Officially documented substitutes include the UFZVFH7.5B for automotive-grade variants. Verify pinout and electrical characteristics before substitution. Ensure replacement parts meet the same AEC-Q101 qualification standards if used in automotive contexts.
