Product Description
Product Overview
The SMSZ4xxx Series Surface Mount Zener Diodes offer a voltage range from 1.8V to 43V with a power dissipation of 500mW. These diodes are designed for high stability and reliability, featuring low zener impedance and excellent ESD capability according to AEC-Q101 standards (Human body mode > 8kV, Machine mode > 800V). They are suitable for applications requiring precise voltage regulation and robust performance. The short duration test pulse is utilized to minimize self-heating effects during testing.
