Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when sourcing this component. The 'G' suffix indicates a lead-free package compliant with RoHS directives. Confirm that the requested part number matches the exact voltage and package variant required for your design, as the datasheet covers a wide series of devices with different electrical parameters.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 10 V reference in a compact surface-mount form factor. Ensure the circuit design accounts for the 500 mW power dissipation limit and derating above 75 °C. Verify that the ±5% voltage tolerance meets the precision requirements of the target application before finalizing the bill of materials.

Single Zener Diodes Part Context

This device belongs to the MMSZxxxET1G series of Zener voltage regulators manufactured by onsemi. The series offers a wide range of reverse voltages from 2.4 V to 56 V in the SOD-123 package. These components serve as alternatives to older leadless packages, providing improved mechanical stability and suitability for modern automated surface-mount manufacturing processes.

Single Zener Diodes Replacement Considerations

Cross-reference with other MMSZ10ET1G variants from onsemi. Devices with the 'SZ' prefix are qualified for automotive applications with unique site and control change requirements. Ensure any substitute maintains the same SOD-123 footprint and electrical specifications.
