DIFF Subgroup
H10F 30/20 the devices having potential barriers, e.g. phototransistors
Introduced: January 2025
Full Title
Individual radiation-sensitive semiconductor devices in which radiation controls the flow of current through the devices, e.g. photodetectors > the devices having potential barriers, e.g. phototransistors
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 2025.
