The MM3Z16VT1G is a Zener voltage regulator designed to provide voltage regulation and protection. It features a nominal Zener voltage of 16.2 V at a test current of 5 mA and a maximum Zener impedance of 40 Ω. This lead-free device has a low reverse leakage current of 0.05 μA at 11.2 V and a maximum power dissipation of 300 mW. Due to its compact SOD-323 package, it is particularly well-suited for space-constrained applications like cellular phones, handheld portables, and high-density PC boards.
