SLVS675D – AUGUST 2006 – REVISED DECEMBER 2014
6.2 ESD Ratings
V_(ESD) Electrostatic discharge
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾
Charged-device model (CDM), per JEDEC specification JESD22-
C101 ⁽²⁾
VALUE
±2000
±1500
(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.
