MM3Z10B

Single Zener Diodes Overview

The MM3Z10B is a surface-mount planar Zener diode manufactured by Diotec Semiconductor in the SOD-323F package. It provides a nominal Zener voltage of 10 V with a tight tolerance of ±2%, ranging from 9.77 V to 10.21 V at a test current (IZ) 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. Electrical characteristics include a dynamic resistance (rzj) of 30 Ω at 1 kHz, a reverse leakage current of 0.1 µA at 7 V, and a typical temperature coefficient of +5...+8 mV/°C.

Single Zener Diodes Feature Summary

• Sharp Zener voltage breakdown characteristic for precise regulation
• Tight ±2% tolerance on Zener voltage
• Low reverse leakage current
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Zener Diodes Applications

• Voltage stabilization circuits
• Voltage regulator designs

Single Zener Diodes Procurement Notes

Verify the specific suffix when ordering: standard commercial grade uses no suffix, AEC-Q101 compliant grade uses -Q, and AEC-Q101 qualified grade uses -AQ. Confirm that the required reliability level matches the application's needs, as standard versions are intended for commercial and industrial use rather than life-support systems.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 10 V reference or clamp in compact designs. Ensure the circuit can handle the 300 mW power dissipation limit at the expected ambient temperature. Verify if automotive-grade qualification (-AQ) is necessary for the target environment, as it dictates the specific manufacturing and testing standards applied to the unit.

Single Zener Diodes Part Context

This part belongs to the MM3Z2B4 through MM3Z75B series of SMD Planar Zener Diodes. The series covers a wide voltage range from 2.4 V to 47 V, all housed in the space-saving SOD-323F package. These devices are designed for general-purpose voltage stabilization and are available in both standard commercial grades and specialized automotive grades.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include MM3Z10B-Q (AEC-Q101 compliant) and MM3Z10B-AQ (AEC-Q101 qualified). Other manufacturers' SOD-323F 10 V Zener diodes may be considered if they match the 300 mW power rating and ±2% tolerance requirements.
