Charged-device model
Encyclopedia
The charged-device model (CDM) is a model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge
(ESD). The model is an alternative to the human-body model (HBM).
Devices that are classified according to CDM are exposed to a charge at a standardized voltage level, and then tested for survival. If it withstands this voltage level, it is tested at the next level and so on, until the device fails.
CDM is standardized by JEDEC
in JESD22-C101E.
Electrostatic discharge
Electrostatic discharge is a serious issue in solid state electronics, such as integrated circuits. Integrated circuits are made from semiconductor materials such as silicon and insulating materials such as silicon dioxide...
