What is the name of the device shown in figure "2" of the illustration? Illustration EL-0068

Correct Answer: Option B — power rectifier diode

Figure 2 depicts a heavy-duty power rectifier diode, identifiable by its threaded stud mounting designed for high-current stud-cooling heatsinks. These semiconductor devices convert alternating current to direct current in marine charging systems, governed by 46 CFR Subchapter J and IEEE 45 standards.
