Single Zener Diodes Procurement Notes

Verify the specific suffix when ordering; standard versions are commercial/industrial grade, while suffixes -Q and -AQ denote AEC-Q101 compliance or qualification respectively. Confirm that the procurement matches the required automotive or standard reliability grade before finalizing orders.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 5.1 V reference in a compact surface-mount footprint. Ensure the design accommodates the 500 mW power dissipation limit on PCBs with 25 mm² copper pads per terminal. Verify thermal resistance requirements against ambient conditions.

Single Zener Diodes Part Context

This part belongs to the MM1Z4689 through MM1Z4717 series of SMD Planar Zener Diodes. The series covers a wide Zener voltage range from 5.1 V to 43 V, providing a standardized solution for various voltage regulation needs across different commercial and industrial product lines.

Single Zener Diodes Replacement Considerations

Direct substitutes include MMSZ4689ET3G (onsemi) and MMSZ4689-E3-18 (Vishay). These alternatives share similar electrical ratings and SOD-123 packaging but may differ in specific marking codes or manufacturing origins.
