5.4 ESD Ratings

VALUE

UNIT

V(ESD)

Electrostatic discharge

Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)

±2000

Charged-device model (CDM), per JEDEC specification JESD22-C101(2)

±1000

(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.
