The 1SMA4728A~1SMA4764A series are Zener diodes designed for voltage regulation applications. They offer low reverse leakage, low Zener impedance, and high stability and reliability. These diodes are suitable for general-purpose use and feature a case that denotes the cathode end with a color band. They are available in a range of Zener voltages from 3.3V to 100V, with a peak pulse power of 1000mW.
