Product Description

Product Overview

The SMSZ4xxx Series Surface Mount Zener Diodes are designed for applications requiring stable voltage regulation. These diodes offer a Zener Voltage (Vz) range from 1.8V to 43V and a Power Dissipation of 500mW. Key features include low zener impedance, high stability, and reliability. They are suitable for various electronic circuits where precise voltage control is essential. The devices are ESD capable according to AEC-Q101 standards, with a Human Body Mode exceeding 8kV and Machine Mode exceeding 800V. A short duration test pulse is used to minimize self-heating effects during testing.
