MM3Z18VST1G Description

Short technical summary and product information.

The MM3Z18VST1G is a Zener voltage regulator diode from onsemi's MM3ZxxxST1G series. It provides a nominal Zener voltage of 18V with a tolerance of ±2%. The device is designed for voltage regulation and protection in space-constrained applications.

 

Key electrical characteristics include a forward voltage of 900mV at 10mA, maximum Zener impedance of 45Ω, and a reverse leakage current of 50nA at 12.6V. The diode offers an ESD rating of Class 3 (>16kV) per the Human Body Model. Power dissipation is rated at 300mW on a single-sided FR-4 board and 500mW on a double-sided board.

 

The device is housed in a SOD-323 surface mount package (SC-76 case) weighing 4.507mg. It supports an operating junction temperature range of -65°C to 150°C and a maximum soldering temperature of 260°C for 10 seconds. The component is Pb-Free, Halogen Free/BFR Free, and RoHS3 compliant.
