SZMMSZ4693T3G

Single Zener Diodes Overview

The SZMMSZ4693T3G is a single Zener voltage regulator diode from the MMSZ4xxxT1G/SZMMSZ4xxxT1G series, manufactured by onsemi. It features a nominal reverse Zener voltage of 7.5 V with a tolerance range of 7.13 V to 7.88 V at a test current (IZT) of 50 µA. The device has a maximum power dissipation rating of 500 mW and operates within a junction temperature range of -55°C to +150°C. It is housed in an SOD-123 surface-mount package (CASE 425). The component is qualified under AEC-Q101 standards for automotive applications and supports PPAP requirements.

Single Zener Diodes Feature Summary

• SZ prefix designation indicates qualification for automotive applications requiring unique site and control change requirements.
• SOD-123 surface mount package designed for optimal automated board assembly and high-density applications.
• Low reverse leakage current characteristics suitable for precision voltage regulation tasks.

Single Zener Diodes Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components.
• Voltage reference applications in industrial systems.
• Clamping and protection circuits in consumer electronics.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix T3G corresponds to the specific tape and reel quantity required for production lines. Confirm that the SZ prefix is necessary to meet project-specific site and control change documentation requirements mandated by automotive quality standards. Ensure compatibility with standard SOD-123 footprints during PCB layout validation.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V Zener reference is needed in a compact surface-mount form factor. The low test current of 50 µA makes it suitable for low-power biasing or reference applications where minimal quiescent current draw is critical. Verify that the 500 mW power rating aligns with the thermal management capabilities of the target printed circuit board substrate.

Single Zener Diodes Part Context

This part belongs to the MMSZ46xx series of silicon Zener diodes offered in the SOD-123 plastic package. The series provides a wide range of nominal voltages from 1.8 V to 43 V. The SZ variant specifically targets markets requiring strict supply chain traceability and manufacturing site controls, distinguishing it from standard commercial grade equivalents within the same electrical family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other MMSZ4693 variants such as MMSZ4693T1G or MMSZ4693T3G from onsemi, noting differences in packaging quantities. Cross-manufacturer replacements must match the 7.5 V nominal voltage, SOD-123 footprint, and AEC-Q101 qualification if automotive compliance is required.
