MMSZ4710T1G

Single Zener Diodes Overview

The MMSZ4710T1G is a Zener voltage regulator diode from the MMSZ4xxxT1G series, manufactured by onsemi. It is housed in an SOD-123 surface-mount package (CASE 425). The device provides a nominal reverse Zener voltage of 25 V with a tolerance range of 23.75 V to 26.25 V at a test current (IZT) of 50 µA. Maximum reverse leakage current is specified as 0.01 µA at a reverse voltage of 19.0 V. Total power dissipation is rated at 500 mW on an FR-5 board at 75°C, derating at 6.7 mW/°C above this temperature. Operating and storage junction temperatures range from -55°C to +150°C.

Single Zener Diodes Feature Summary

• Low reverse current specification for reduced standby power consumption
• SOD-123 package designed for optimal automated board assembly and high-density applications
• ESD rating of Class 3 (> 16 kV) per Human Body Model
• Lead-free construction compliant with RoHS standards

Single Zener Diodes Applications

• Voltage regulation in low-power electronic circuits
• Reference voltage sources in measurement systems
• Over-voltage protection in signal lines

Single Zener Diodes Procurement Notes

Verify the specific part marking code DY against the official datasheet table to confirm the 25 V nominal voltage rating. Ensure the ordering suffix matches the required packaging format, such as T1G for tape and reel quantities. Confirm compliance requirements including RoHS status and lead-free finish before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 25 V reference is needed in a compact surface-mount footprint. Consider the thermal resistance characteristics and derating curves if operating near maximum power limits. Evaluate the low leakage current requirement against circuit sensitivity needs compared to other series options.

Single Zener Diodes Part Context

This device belongs to the MMSZ4xxxT1G series of Zener diodes offered by onsemi. The series covers a wide reverse voltage range from 1.8 V to 43 V within the same SOD-123 package style. These devices serve as alternatives to traditional leadless packages, providing flexibility for automated assembly processes while maintaining consistent electrical performance across the voltage spectrum.

Single Zener Diodes Replacement Considerations

SZMMSZ4710T1G is an automotive-grade variant within the same series offering AEC-Q101 qualification and PPAP capability.
