... 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 LAN8710 to 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 LAN8710 can safely dissipate ± ...
