ESD Models:

HBM (Human Body Model)

The Human Body Model ESD is a modeling of a situation where a certain amount of energy from an external electrical power or an electrostatic energy source becomes charged within the human body to become discharged as electrostatic energy.

MM (Machine Model)

The Machine Model is a modeling of a situation where electrostatic energy is charged within the machine through a grounding problem or some other negative influence.

CDM (Charged Device Model)

The Charged Device Model is when an electric charge within the Package becomes discharged through an external conductive material, and the device is damaged through a self-discharge. This model is different from other electrostatic discharge models in that the Pulse duration is very short, which causes Oxide failures such as oxide or poly-filament breakdown.
