MM3Z3V9ST1G Description

Short technical summary and product information.

The MM3Z3V9ST1G is a Zener voltage regulator diode from On Semiconductor's MM3ZxxxST1G series. It provides a nominal Zener voltage of 3.9V with a tight ±2% tolerance, making it suitable for precision voltage regulation applications.

 

This diode offers a maximum power dissipation of 300mW on an FR-4 board at 25°C (500mW under certain conditions) and features a low maximum Zener impedance of 90Ω. It has a maximum reverse leakage current of 3µA at 1V and a typical forward voltage of 900mV at 10mA.

 

The device is housed in a compact SOD-323 surface-mount package, ideal for space-constrained designs. It is rated for an operating junction temperature range of -65°C to 150°C and has an ESD rating of Class 3 (>16kV) per the Human Body Model. The component is Pb-free, Halogen Free/BFR Free, and RoHS compliant.
