Single Zener Diodes Procurement Notes

Verify the exact part number spelling upon receipt, as the provided input 'SMMSZ5252BT1G' differs from the standard manufacturer designation 'SZMMSZ5252BT1G'. Confirm that the received components match the SOD-123 package type and the specified 24 V Zener voltage characteristics. Ensure compliance with RoHS standards and AEC-Q101 qualification requirements if applicable to your specific design constraints.

Single Zener Diodes Selection Notes

Select this component when a 24 V regulation point is required in a space-constrained surface-mount layout. The 500 mW power rating supports moderate current applications without excessive heat sinking. Consider the 5% voltage tolerance and 33 Ω dynamic impedance for circuit stability requirements. The wide operating temperature range makes it suitable for industrial environments.

Single Zener Diodes Part Context

This device belongs to the MMSZ52 series of Zener diodes offered by onsemi. The series utilizes the SOD-123 plastic package, providing an alternative to traditional leadless styles. These regulators are designed for general-purpose voltage regulation tasks across various consumer and industrial electronics applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other MMSZ52xxBT1G variants with different voltage ratings from onsemi. Cross-manufacturer equivalents should be verified against the 24 V nominal voltage, 500 mW power dissipation, and SOD-123 footprint specifications.
