MM3Z3V9

Single Zener Diodes Overview

The MM3Z3V9 is a surface-mount planar Zener diode manufactured by Diotec Semiconductor, housed in an SOD-323F package. It provides a nominal Zener voltage of 3.9 V with a tolerance of ±5%. 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 maximum dynamic resistance of 85 Ohms at 1 kHz, a reverse leakage current of 5 µA at 1.0 V, and a test current of 5 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear voltage regulators

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. Standard versions are commercial grade, while suffixes like -Q indicate AEC-Q101 compliance and -AQ indicates qualification. Confirm mechanical data such as tape-and-reel packaging dimensions and moisture sensitivity level prior to procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable reference voltages near 3.9 V. Ensure the operating environment stays within the specified thermal limits to maintain performance. Consider the dynamic impedance when designing for high-frequency stability. Verify that the power dissipation requirements do not exceed the 300 mW rating under worst-case ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the MM3Z series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V in the compact SOD-323F package. These devices are designed for general-purpose voltage regulation and protection in commercial and industrial electronic equipment.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 3.9 V Zener voltage, SOD-323F package, and 300 mW power rating. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit compatibility.
