Single Zener Diodes Procurement Notes

Verify component status as Not Recommended for New Designs (NRND). Confirm AEC-Q101 qualification aligns with target automotive or industrial specifications. Ensure SOT-23-3 footprint compatibility during PCB layout review. Validate thermal management capabilities against the 250 mW power dissipation limit in final assembly conditions.

Single Zener Diodes Selection Notes

Select this component when precise voltage reference stability is required in space-constrained designs. The narrow voltage tolerance suits applications demanding accurate threshold detection. Consider the high operating temperature range for environments with significant thermal stress. Verify that the 5 mA test current matches the biasing conditions of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the ROHM BZX84 series of single Zener diodes. The series offers various voltage options in the same SOT-23-3 package family. The 'B' suffix indicates tighter voltage tolerance compared to standard variants. The LFHT116 suffix denotes specific tape and reel packaging configuration for automated assembly processes.
