TZMB4V3-GS08

Single Zener Diodes Overview

The Vishay TZMB4V3-GS08 is a single-channel silicon epitaxial planar Zener diode in the MiniMELF (SOD-80) surface-mount package. It provides a nominal Zener voltage of 4.3 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 1 μA, a dynamic resistance of 90 Ω, and a temperature coefficient ranging from -0.06%/K to -0.03%/K.

Single Zener Diodes Feature Summary

• Features a very sharp reverse characteristic for precise voltage regulation
• Ensures very high stability and low noise performance
• Maintains extremely low reverse current levels

Single Zener Diodes Applications

• Voltage stabilization circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code suffix matches GS08 to confirm the specific SOD-80 packaging format. Ensure compliance requirements align with material categorization definitions provided by the manufacturer. Confirm that the component meets AEC-Q101 automotive standards if required for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a tight ±2% voltage tolerance is required compared to the standard ±5% option. Consider the negative temperature coefficient for low-voltage applications where thermal drift must be accounted for. Verify that the 500 mW power dissipation rating suits the ambient operating conditions without excessive derating.

Single Zener Diodes Part Context

This part belongs to the Vishay TZM-Series of small signal Zener diodes. The series utilizes silicon epitaxial planar technology housed in the MiniMELF glass package. The 'B' designation specifically indicates the tighter ±2% Zener voltage tolerance class within the product family.

Single Zener Diodes Replacement Considerations

TZMC4V3-GS08 offers identical physical characteristics but with a wider ±5% voltage tolerance.
