VALUE UNIT
V(ESD) Electrostatic discharge Human-Body Model (A114-A)(1) ±1500 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000
Machine Model (A115-A) ±200
(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.
