MM3Z9V1ST1G Description

Short technical summary and product information.

The MM3Z9V1ST1G is a Zener voltage regulator diode from the MM3ZxxxST1G series by onsemi. It provides a nominal Zener breakdown voltage of 9.1V with a tight tolerance of ±2%, suitable for precision voltage regulation applications.

 

Key electrical characteristics include a maximum power dissipation of 300mW at 25°C ambient on FR-4 board (Note 1), a forward voltage of 900mV at 10mA test current, and a zener impedance of 15Ω. The device exhibits a reverse leakage current of 500nA maximum at 6V reverse voltage. It is rated for an operating junction temperature range of -65°C to +150°C. The ESD rating is >16kV per the Human Body Model.

 

This diode is housed in a small SOD-323 surface mount package with body dimensions of 1.7mm x 1.25mm x 0.9mm and a weight of 4.507mg. The package is molded with UL 94 V-0 flammability rating. According to the datasheet, the device is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. It is designed for space-constrained applications such as portable electronics and high-density PC boards.
