(ESD)
Electrostatic discharge
Human body model (HBM), per ANSI/ESDA/JEDEC JS-001
(1)
±2000
V
Charged device model (CDM), per JEDEC specification JESD22-C101
(2)
±500
(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.
