SZMM3Z12VT1G Description

Short technical summary and product information.

The SZMM3Z12VT1G is a 12V Zener voltage regulator diode from ON Semiconductor, part of the SZMM3ZxxxT1G series. It provides a nominal Zener voltage of 12V with ±5% tolerance and a maximum impedance of 25Ω. The device is rated for 300mW power dissipation on an FR-4 board at 25°C, with a thermal resistance of 416°C/W junction-to-ambient. It features a low forward voltage of 900mV at 10mA and a reverse leakage current of 100nA at 8V.

 

The diode is housed in a SOD-323 surface mount package, ideal for space-constrained designs. It operates over a junction and storage temperature range of -65°C to 150°C. The SZ prefix indicates AEC-Q101 qualification, making it suitable for automotive and other applications requiring stringent reliability. The device also boasts an ESD rating of Class 3 (>16 kV) per the Human Body Model.

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in portable electronics, automotive modules, and high-density PCBs. The SOD-323 package allows for efficient use of board space while maintaining robust performance.
