The SZMM3Z5V1T1G is a Zener voltage regulator designed to provide voltage regulation and protection. This device features a nominal Zener voltage of 5.1V at a test current of 5 mA, a steady-state power rating of 300 mW, and a maximum forward voltage of 0.9V at 10 mA. With a low reverse leakage current of 2 µA at 2.0V, this component is AEC-Q101 qualified, indicating its suitability for automotive applications. Its small SOD-323 package makes it ideal for space-constrained situations such as cellular phones, handheld portables, and high-density PC boards.
