VALUEUNIT
V(ESD)Electrostatic discharge(3)Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)±2000V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2)±750
(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 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
