... HBM testing verifies the ability to withstand the ESD strikes like those that occur during handling and manufacturing, and is done without power applied to the IC. To pass the test, the device must have no change in operation or performance due to the event. All pins on the LAN8700 provide ±8kV HBM protection.

... ESD strikes while the end equipment is operational. In contrast, the HBM ESD tests are performed at the device level with the device powered down. SMSC contracts with Independent laboratories to test the LAN8700 to EN/IEC61000-4 working system. Reports are available upon request. Please contact your SMSC representative, and request information on 3rd party ESD test results. The reports show that systems designed with the LAN8700 can safely dissipate ± ...
