Human body model

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 3015.7, Electrostatic Discharge Sensitivity Classification. This method establishes a simplified equivalent circuit and the necessary test procedures required to model an HBM ESD event.

Model

In 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.
