Single Zener Diodes Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and packaging compatibility. Ensure the ordering part number matches the required tape-and-reel quantity. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 12V reference with high thermal endurance is required in compact spaces. The SOD-123FL footprint allows for dense PCB layouts. Verify that the 20mA test current aligns with the circuit's biasing requirements and that the 1W power dissipation capacity suits the thermal environment.

Single Zener Diodes Part Context

This part belongs to the KDZV series of small-power molded Zener diodes. It serves as a recommended replacement for legacy parts like the KDZ12B, which is no longer recommended for new designs. The series focuses on providing stable voltage references in minimal footprints suitable for modern electronic assemblies.
