SZMMSZ4704T1G

Single Zener Diodes Overview

The SZMMSZ4704T1G is a single Zener diode from the MMSZ4xxxT1G series, manufactured by onsemi. It provides a nominal reverse Zener voltage of 17 V with a tolerance range of 16.15 V to 17.85 V at a test current (IZT) of 50 µA. The device features a maximum reverse leakage current of 50 nA at a reverse voltage of 12.9 V and a maximum forward voltage of 0.9 V at 10 mA. It operates within a junction temperature range of -55°C to +150°C and dissipates up to 500 mW on an FR-5 board. The component is housed in a surface-mount SOD-123 package.

Single Zener Diodes Feature Summary

• SZ prefix indicates qualification for automotive applications requiring unique site and control change requirements, including AEC-Q101 qualification and PPAP capability.
• Designed for optimal automated board assembly with a small package size suitable for high-density applications.
• Features low reverse current characteristics and an ESD rating of Class 3 (> 16 kV) per the Human Body Model.

Single Zener Diodes Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components
• High-density surface mount PCB designs
• Voltage regulation and reference applications

Single Zener Diodes Procurement Notes

Verify that the specific order includes the 'SZ' prefix to ensure compliance with automotive site and control change requirements. Confirm AEC-Q101 qualification status and PPAP capability are required for the intended application environment. Ensure the procurement matches the exact suffix 'T1G' for the specified tape and reel packaging configuration.

Single Zener Diodes Selection Notes

Select this component when a 17 V Zener voltage is required in a compact SOD-123 footprint. Consider the SZ prefix specifically for automotive projects necessitating strict supply chain controls and AEC-Q101 certification. Evaluate the low test current requirement against circuit biasing capabilities to ensure stable operation within the specified thermal limits.

Single Zener Diodes Part Context

This part belongs to the MMSZ4xxxT1G and SZMMSZ4704T1G series of 500 mW Zener diodes. These devices serve as a convenient alternative to leadless 34-package styles while maintaining surface mount compatibility. The series covers a wide Zener voltage range from 1.8 V to 43 V, offering standardized performance across various voltage ratings.

Single Zener Diodes Replacement Considerations

The MMSZ4704T1G is a non-SZ variant of the same electrical specification. Verify if the automotive-specific SZ prefix and associated quality documentation are mandatory before substituting with standard commercial grade parts.
