IEN/IEC61000-4-2 Performance
The EN/IEC61000-4-2 ESD specification is an international standard that addresses system-level
immunity to 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/IEC61000-4-2 in a 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 ±15kV air discharges and ±8kV contact discharges per the EN/IEC61000-4-2
specification without additional board level protection.
In addition to defining the ESD tests, EN/IEC61000-4-2 also categorizes the impact to equipment
operation when the strike occurs (ESD Result Classification). The LAN8700 maintains an ESD Result
Classification 1 or 2 when subjected to an EN/IEC61000-4-2 (level 4) ESD strike.
Both air discharge and contact discharge test techniques for applying stress conditions are defined by
the EN/IEC61000-4-2 ESD document.
AIR DISCHARGE
To perform this test, a charged electrode is moved close to the system being tested until a spark is
generated. This test is difficult to reproduce because the discharge is influenced by such factors as
humidity, the speed of approach of the electrode, and construction of the test equipment.
CONTACT DISCHARGE
The uncharged electrode first contacts the pin to prepare this test, and then the probe tip is energized.
This yields more repeatable results, and is the preferred test method. The independent test laboratories
contracted by SMSC provide test results for both types of discharge methods.
