Human Body Model Testing
As the name implies, this test method emulates the ESD
event delivered to an IC during human handling. The tester
delivers the charge stored on a 100pF capacitor through a
1.5kΩ current limiting resistor into the pin under test. The

HBM method determines an ICs ability to withstand the ESD
events typically present during handling and manufacturing.
The RS-485 pin survivability on this high ESD family has
been characterized to be in excess of ±15kV, for discharges
to GND.
