SZMMSZ15ET1G

Single Zener Diodes Overview

The SZMMSZ15ET1G is a single-channel Zener voltage regulator diode manufactured by onsemi. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Packaged in the surface-mount SOD-123 format, it has two pins and a maximum reverse leakage current of 50 nA. The component is designed for automated board assembly and offers high-density application suitability.

Single Zener Diodes Feature Summary

• Automotive-grade qualification under AEC-Q101 standards
• PPAP capable for automotive supply chain requirements
• ESD protection rating exceeding 16 kV per Human Body Model
• SOD-123 package optimized for automated assembly

Single Zener Diodes Applications

• Automotive electronic circuits requiring unique site control
• General-purpose voltage regulation in industrial systems
• Protection against electrostatic discharge in sensitive interfaces

Single Zener Diodes Procurement Notes

Verify that the part number prefix 'SZ' is explicitly required, as it denotes AEC-Q101 qualification and PPAP capability for automotive applications. Confirm the specific revision level matches your design documentation. Ensure the sourcing channel provides traceability records consistent with automotive quality management standards.

Single Zener Diodes Selection Notes

Select this component when automotive reliability standards are mandatory. The SZ prefix indicates stricter manufacturing controls compared to standard MMSZ series parts. Verify that the 500 mW power rating and SOD-123 footprint align with the thermal and spatial constraints of the target PCB layout.

Single Zener Diodes Part Context

This component belongs to the MMSZxxxET1G and SZMMSZxxxET1G series of Zener voltage regulators. These devices provide a surface-mount alternative to leadless packages, offering wide reverse voltage ranges from 2.4 V to 56 V. The series is engineered for high-density applications with small physical dimensions suitable for modern automated assembly processes.

Single Zener Diodes Replacement Considerations

Standard MMSZ15ET1G may be considered if automotive qualification is not required. Other variants within the MMSZ15T1G family offer similar electrical characteristics but lack the specific automotive site control attributes.
