The MM3Z3V0CW is a SOD-323-packaged Zener diode manufactured by the Taiwanese semiconductor firm Tak Cheong, which is compliant with the Restriction of Hazardous Substances (RoHS) Directive. It is characterized by a wide range of operation voltage with a relatively high zener voltage, combined with a low reverse current. With these features, it is designed for applications such as voltage reference, address buffers, line drivers, level translators, power supplies, and regulators.
