MM9Z3V3

Single Zener Diodes Overview

The MM9Z3V3 is a surface-mount planar Zener diode manufactured by Diotec Semiconductor, designed for voltage stabilization and regulation applications. It operates within a junction temperature range of -55°C to +150°C and features a maximum power dissipation of 250 mW when mounted on a PCB with 3 mm² copper pads at each terminal. The device provides a nominal Zener voltage of 3.3 V with a tolerance of ±5%, ensuring sharp breakdown characteristics. It is available in miniature SOD-882 or DFN1006-2 packages, making it suitable for space-constrained commercial and industrial electronic designs.

Single Zener Diodes Procurement Notes

Verify the specific package variant (SOD-882 or DFN1006-2) required for your design, as both are supported by this part number series. Confirm if an automotive-grade suffix (-Q or -AQ) is necessary for AEC-Q101 compliance. Ensure the application environment remains within the specified commercial/industrial reliability standards, as the standard version is not intended for life-support systems.

Single Zener Diodes Selection Notes

Select the MM9Z3V3 when a stable 3.3 V reference is needed in a small footprint. The component offers a tight ±5% voltage tolerance and low dynamic resistance. Consider the thermal derating curve if ambient temperatures exceed standard conditions. Verify that the 250 mW power rating aligns with the expected current draw and PCB copper pad dimensions for optimal heat dissipation.

Single Zener Diodes Part Context

This component belongs to the MM9Z3V3...MM9Z5V1 series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide range of Zener voltages from 2.4 V to 47 V, all sharing similar mechanical and electrical characteristics. These devices are engineered for general-purpose voltage regulation tasks in modern electronics manufacturing.
