MMSZ5231C-E3-08

Single Zener Diodes Overview

The MMSZ5231C-E3-08 is a silicon planar Zener diode manufactured by Vishay Semiconductors in the SOD-123 surface-mount package. It provides a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%. The device operates at a test current of 20 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a dynamic resistance of 17 Ω, and a temperature coefficient of 0.00 %/°C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar construction for robust performance
• Offers high precision with a ±2% Zener voltage tolerance
• Designed for automated assembly processes
• Compliant with RoHS standards and free from halogen and antimony

Single Zener Diodes Applications

• Voltage reference circuits requiring stable potential
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required ±2% tolerance suffix 'C' and the 3000-unit reel packaging format. Confirm compliance with AEC-Q101 requirements if automotive qualification is necessary, as this specific commercial grade variant does not carry that qualification. Ensure storage conditions align with moisture sensitivity level 1 specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow ±2% tolerance band compared to standard ±5% variants. The zero temperature coefficient near 5.1 V makes it suitable for applications where thermal stability is paramount. Consider the SOD-123 footprint constraints and the 500 mW power dissipation limit relative to the expected operating environment.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225 to MMSZ5267 series of small signal Zener diodes. The series covers a wide range of voltages from 3.0 V to 75 V. The 'C' suffix specifically denotes the tighter manufacturing tolerance, while the 'E3' indicates RoHS compliance. These devices are engineered for general-purpose use in compact surface-mount designs.

Single Zener Diodes Replacement Considerations

MMSZ5231B-E3-08 offers identical physical and electrical parameters except for a wider ±5% voltage tolerance.
