Human body model
Encyclopedia
The human-body model is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge
(ESD). The model is a simulation of the discharge which might occur when a human touches an electronic device.
The HBM definition most widely used is the test model defined in the United States
military standard, MIL-STD-883, Method 3015.8, Electrostatic Discharge Sensitivity Classification. This method establishes a simplified equivalent electrical circuit and the necessary test procedures required to model an HBM ESD event.
An internationally widely used standard is JEDEC standard JS-001.

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...

Model
In both JS-001-2010 and MIL-STD-883G the charged human body is modeled by a 100 pF capacitorCapacitor
A capacitor is a passive two-terminal electrical component used to store energy in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors separated by a dielectric ; for example, one common construction consists of metal foils separated...

Resistor
A linear resistor is a linear, passive two-terminal electrical component that implements electrical resistance as a circuit element.The current through a resistor is in direct proportion to the voltage across the resistor's terminals. Thus, the ratio of the voltage applied across a resistor's...
