6.2 ESD Ratings

VALUEUNIT
VESD(1)Electrostatic DischargeHuman body model (HBM), per ANSI/ESDA/JEDEC JS–001, all pins(2)±2000V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(3)±500
(1) Electrostatic discharge (ESD) to measure device sensitivity and immunity to damage caused by assembly line electrostatic discharges into the device.
(2) JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process. Pins listed as 1000V can have higher performance.
(3) JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process. Pins listed as 250V can have higher performance.
