Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the diodes are separated and packaged as individual components
Packaged diodes, including Schottky diodes, fall under the specific subheading for diodes.
If the wafer contains transistors rather than diodes
Transistor dice on wafers are classified under the transistor subheadings when separated.
If the wafer includes integrated control circuitry
Wafers combining power devices with integrated circuits may be classified as electronic integrated circuits.
