TZMC4V3-GS18

Single Zener Diodes Overview

The TZMC4V3-GS18 is a silicon epitaxial planar Zener diode from the Vishay TZM series, housed in a MiniMELF (SOD-80) surface-mount package. It provides a nominal Zener voltage of 4.3 V with a tolerance of ±5%. The device operates at a test current of 5 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 2 V and a dynamic resistance of less than 90 Ω.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging details. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the requested quantity aligns with standard reel sizes or cut tape availability specified by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a stable 4.3 V reference is required in a compact SMD footprint. The ±5% tolerance suits general-purpose applications where tight precision is not critical. Consider the thermal impedance and power dissipation limits relative to the ambient operating temperature of the target circuit.

Single Zener Diodes Part Context

This part belongs to the TZM series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes silicon epitaxial planar technology and is available in various voltage ratings within the MiniMELF package format.

Single Zener Diodes Replacement Considerations

Cross-reference with other Vishay TZM-series variants such as TZMB4V3-GS18 for tighter tolerance requirements. Verify pinout compatibility and thermal characteristics before substituting with components from different manufacturers.
