H10F 30/28

the devices being characterised by field-effect operation, e.g. junction field-effect 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 > the devices being sensitive to infrared, visible or ultraviolet radiation > the devices being characterised by field-effect operation, e.g. junction field-effect phototransistors

CPC subdivides this area 5x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.

IPC defines codes here since 2025.
