Human-Body-Model stresses devices by sudden application of a high voltage supplied by a 100pF capacitor through 1.5k-ohm resistance.

Testing was started at 5.0V (Positive) or 0V (Negative), and the DUT was biased for 0.5 seconds. If neither the PUT current supply nor the device current supply reached the predefined limit (DUT=00mA, Icc=100mA), then the voltage was increased by 0.1Volts and the pin was tested again. This procedure was recommended by the JEDEC JC-40.2 CMOS Logic standardization committee. Notes: 1. DUT: Device Under Test. 2. PUT: Pin Under Test.
