This document introduces the features and characteristics of the MMSZ4678T1 series Zener diodes. These diodes are available in a convenient, surface mount plastic SOD−123 package, providing an alternative to the leadless 34-pin package style.
The document describes the MMSZ4678T1 Series Zener Voltage Regulators, which are offered in convenient, surface mount plastic SOD-123 packages. These devices serve as an alternative to leadless 34-package styles and provide a wide Zener reverse voltage range from 1.8 V to 43 V. The series includes Pb-free package options and is designed for optimal automated board assembly with a small package size suitable for high-density applications.
