MMSZ5225B-E3-08

Single Zener Diodes Overview

The MMSZ5225B-E3-08 is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 3 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW in the SOD-123 surface-mount package. Key electrical parameters include a maximum reverse leakage current of 50 µA at 1 V, a dynamic resistance of 30 Ω, and an operating temperature range from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Silicon planar construction for reliable voltage regulation
• Standard ±5% Zener voltage tolerance for general applications
• ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant commercial grade material categorization

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify that the ordering code matches MMSZ5225B-E3-08 to ensure the correct ±5% tolerance and non-AEC-Q101 qualification status. Confirm the package type is SOD-123 and check the datasheet for specific thermal resistance values required for your power dissipation calculations. Ensure compliance with RoHS standards if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 3 V Zener voltage with ±5% tolerance is required. The SOD-123 package suits space-constrained surface-mount designs. Consider the MMSZ5225C variant if tighter ±2% tolerance is necessary. Verify that the 500 mW power dissipation rating meets the thermal requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225 to MMSZ5267 series of small signal Zener diodes. The 'B' suffix indicates the standard ±5% voltage tolerance, while the '-E3-08' suffix denotes RoHS compliance and tape-and-reel packaging on a 7-inch reel. These devices are designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

MMSZ5225C-E3-08 offers identical physical characteristics but with a tighter ±2% voltage tolerance.
