VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±500
IEC 61000-4-2 contact discharge(3) ±8000
IEC 61000-4-2 air-gap discharge(3) ±15000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
(3) Discharges applied to circuit of Figure 22 between RJ-45, adapter, and output voltage rails, on TPS2372- 4EVM-006 Evaluation Module.
