Working Principles

The SMBG18CA-E3/5B operates as a rectifier diode, allowing current to flow in only one direction. When the anode is at a higher potential than the cathode, the diode conducts, regulating the voltage across the circuit. In reverse bias, it blocks the flow of current, providing overvoltage protection.
