MM3Z24

Single Zener Diodes Overview

The MM3Z24 is a surface-mount planar Zener diode manufactured by Diotec Semiconductor, housed in an SOD-323F package. It provides a nominal Zener voltage of 24 V with a tolerance range of 22.8 V to 25.6 V at a test current of 5 mA. The device features a maximum power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a dynamic resistance of less than 70 ohms at 1 kHz and a reverse leakage current of 0.1 µA at 19 V. Standard versions are graded to the E24 series.

Single Zener Diodes Feature Summary

• Sharp Zener voltage breakdown for precise regulation
• Low leakage current under reverse bias conditions
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The standard commercial version lacks automotive qualification. If AEC-Q101 compliance or qualification is required, confirm the presence of the -Q or -AQ suffixes respectively. Ensure the selected variant matches the reliability standards of the target application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable reference voltages near 24 V in compact designs. The SOD-323F package supports automated surface-mount assembly. Consider thermal derating if ambient temperatures exceed standard operating ranges. Verify that the 300 mW power dissipation limit accommodates the expected continuous current load without exceeding the maximum junction temperature.

Single Zener Diodes Part Context

This component belongs to the MM3Z2V4 through MM3Z47 series of SMD planar Zener diodes. The series covers a wide voltage range from 2.4 V to 47 V in the SOD-323F package. The MM3Z24 specifically addresses mid-range voltage requirements within this lineup, offering standardized E24 tolerance grading for general-purpose commercial and industrial electronic designs.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 24 V nominal voltage, SOD-323F package, and 300 mW power rating. Verify dynamic resistance and leakage current specifications against the original datasheet to ensure circuit performance is maintained during cross-brand replacement.
