DIFF Subclass Not Allocatable
H10D

INORGANIC ELECTRIC SEMICONDUCTOR DEVICES

Introduced: January 2025

Description

H10D covers inorganic semiconductor devices and solid-state electronic components not classified elsewhere in section H10. This subclass encompasses a broad range of semiconductor technologies including diodes, transistors, thyristors, and other discrete or integrated inorganic semiconductor devices based on materials such as silicon, germanium, gallium arsenide, and similar compounds. It serves as a residual category for inorganic semiconductor inventions that do not fall within the more specialized subclasses H10B (semiconductor devices with at least one potential-jump barrier or surface barrier), H10F (unspecified semiconductor devices), or other dedicated H10 classifications. Typical applications include power electronics, microwave devices, and specialized semiconductor components for which no specific classification exists.

IPC and CPC are identically structured here. All 17 subcodes exist in both systems.

4 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2025.
