More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the wafer is diced into individual transistor chips
Diced transistor chips would be classified as transistors rather than diodes.
If the wafer contains integrated circuits rather than discrete diode structures
Wafers with monolithic integrated circuits fall under electronic integrated circuits.
If the wafer includes additional elements beyond the diode junctions
Parts of semiconductor devices are classified separately when not meeting the definition of complete devices.
