Human-body model
The human-body model (HBM) 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.
Model
In both JS-001-2010 and MIL-STD-883G the charged human body is modeled by a 100 pF capacitor and a 1500 ohm discharging resistance. During testing, the fully charged capacitor is discharged through the resistor connected in series to the device under test.
