5.2 ESD Ratings

VALUEUNIT
V(ESD)Electrostatic dischargeHuman-body model (HBM), per AEC Q100-002 (1)±2000V
Charged-device model (CDM), per AEC Q100-011, all pins (2)±500
V(ESD)Electrostatic dischargeCharged-device model (CDM), per AEC Q100-011, corner pins (2)±750V
(1) Level listed above is the passing level per ANSI, ESDA, and JEDEC JS-001. JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500V HBM is possible with the necessary precautions.
(2) Level listed above is the passing level per EIA-JEDEC JESD22-C101. JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250V CDM is possible with the necessary precautions.
