VALUEUNIT
V(ESD)Electrostatic discharge(3)Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1)±2kV
Charged-device model (CDM), per JEDEC specification JESD22- C101(2)±500V
(1) JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process.
(3) The human-body model is a 100-pF capacitor discharged through a 1.5kΩ resistor into each pin.
