The 1SMA4754AG with Zener Diodes SMA RoHS manufactured by Shikues is a two-terminal, two-lead, electrically controlled device made of semiconductor material. It is mainly used for voltage regulation, switching, signal clipping, or waveform generation. This type of device is designed in such a way that when it is exposed to a voltage over its breakdown voltage, it lets current pass in one direction. Additionally, it provides protection against electrical surges and transients, and can work as a limiter or rectifier. It meets the standards of the Restriction on Hazardous Substances (RoHS), and is suitable for devices that require higher amounts of power and lower breakdown voltages.
