21.0 Electrostatic Discharge: CI 280
The component shall be immune from overstress due to Electrostatic Discharge (ESD). These requirements are applicable to
the following component categories:
Electronic Modules: A, AS, AM, AX, AY, AW
Electric Motors: Categories EM
Passive Modules: P
** ESD Testing shall be performed prior to any other EMC validation testing **
21.1 Requirements
• The component shall be immune to ESD events that occur during normal handling and assembly. These requirements
are listed in Table 21-1.
• The component shall be immune to ESD events that can occur during normal operation (i.e. powered). These
requirements are listed in 21-2. This includes components in direct access from within the passenger compartment or
trunk, or by direct access through an open window from a person outside the vehicle (e.g. door locks, turn signal
stalk). The requirement also covers components that are not directly accessible.
• After exposure to ESD events listed in Tables 21-1 and 21-2, component I/O parametric values (e.g., resistance,
capacitance, leakage current, etc.) shall remain within their specified tolerances. This may be performed immediately
following ESD testing (recommended) or upon completion of all EMC related testing.

21.2 Test Verification and Test Setup
Testing shall be performed in accordance with ISO 10605-2001 except were noted in this specification. The test facility shall
be maintained at an ambient temperature at (23 ±5) °C and a relative humidity from 20 % to 40 %
The ESD simulator waveform verification shall comply with ISO 10605-2001 with the following exceptions:
• Contact discharge rise time ≤ 1 ns
• Air discharge rise time ≤ 20 ns
The RC time constant shall be verified by calculation using the exponentially decaying portion of the waveform after the
leading edge and/or ringing.
