MMS3Z7B5GW

Single Zener Diodes Overview

The MMS3Z7B5GW is a surface-mount planar Zener diode manufactured by Diotec Semiconductor, housed in an SOD-323 package. It features a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device dissipates up to 300 mW and operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a dynamic resistance of 30 ohms at a test current of 5 mA, a reverse leakage current of 0.5 µA at the rated voltage, and a positive temperature coefficient ranging from +2.5% to +5.3% per degree Celsius.

Single Zener Diodes Feature Summary

• Provides approximately ±2% tolerance for precise Zener voltage regulation
• Features sharp breakdown characteristics for stable voltage clamping
• Maintains low reverse leakage current under operating conditions

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear and switching voltage regulators

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering. The standard version meets commercial and industrial grade requirements. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm that the required automotive or standard grade aligns with the project specifications before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring tight voltage accuracy due to its ±2% tolerance. Ensure the circuit design accommodates the 300 mW power dissipation limit and the specified thermal resistance. Verify that the positive temperature coefficient fits the stability requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the MMS3Z series of SMD Planar Zener Diodes produced by Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 43 V in the compact SOD-323 case outline. These components are designed for general-purpose voltage regulation tasks in commercial and industrial electronic equipment.

Single Zener Diodes Replacement Considerations

Cross-referencing requires matching the 7.5 V nominal voltage, ±2% tolerance, SOD-323 package, and 300 mW power rating. Verify that substitute devices offer comparable dynamic resistance and leakage current specifications to maintain circuit performance.
