EN61000-4-2 Performance
The EN61000-4-2 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.
In addition to defining the ESD tests, EN61000-4-2 also categorizes the impact to equipment operation
when the strike occurs (ESD Result Classification). The LAN8187 maintains an ESD Result
Classification 1 or 2 when subjected to an EN61000-4-2 (level 4) ESD strike.
Both air discharge and contact discharge test techniques for applying stress conditions are defined by
the EN61000-4-2 ESD document.
AIR DISCHARGE
To perform this test, a charged electrode is moved close to the system being tested until a spark is
generated. All pins of the LAN8187 can safely dissipate +/- 15kV air discharges per the EN61000-4-2
specification without additional board level protection. 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. All pins of the LAN8187 can
safely dissipate +/- 8kV contact discharges per the EN61000-4-2 specification without the need for
additional board level protection.
