Overview
The SZMM3Z4V7ST1G is a Zener diode voltage regulator produced by onsemi, packaged in a SOD-323 surface mount package. This component is designed to provide voltage regulation protection and is particularly useful in applications where space is limited. It is well-suited for use in cellular phones, handheld portables, and high-density PC boards.
The device features a steady-state power rating of 300 mW and a standard Zener breakdown voltage range from 2.4 V to 75 V. It is also ESD rated to Class 3 (>16 kV) per the Human Body Model and is Pb-free, halogen-free, and RoHS compliant. The SZ prefix indicates that it is AEC-Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements.
