Single Zener Diodes Procurement Notes

Verify that the specific part code matches the required electrical parameters and packaging format. Confirm RoHS III compliance status and lead exemption details against the latest specification sheet. Ensure the supplier provides valid documentation for REACH SVHC substances before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 24V Zener reference is required in a compact SOD-123 footprint. Consider the 0.5W power rating and thermal resistance limits for heat dissipation requirements. Verify compatibility with standard reflow soldering profiles and ensure the ±5% voltage tolerance meets the circuit design specifications.

Single Zener Diodes Part Context

This component belongs to the MMSZ series of SMD Zener diodes manufactured by NextGen Components. It serves as a cross-reference equivalent to parts originally produced by MDD Diodes under the same model number. The product line covers a wide Zener reverse voltage range from 2.4V to 43V in the SOD-123 case.
