Product Description

Product Overview

The SMSZ4xxx Series Surface Mount Zener Diodes offer a Zener 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 ideal for applications requiring precise voltage regulation and robust performance in a compact SOD-123 package. The short duration test pulse is utilized to minimize self-heating effects during testing.

Product Attributes

  • Package Type: SOD-123
  • ESD Capability: AEC-Q101 compliant (Human body mode > 8kV, Machine mode > 800V)
