4 ESD SENSITIVITY LEVELS

This ESD control plan establishes a baseline for hardware that is sensitive to Human Body Model

(HBM) type events of voltage level Class 1A. Requirements are also included for hardware that is more sensitive such as HBM Class 0 or Charged Device Model (CDM) Class C1. The sensitivity levels and models are defined by Electrostatic Discharge Association (ESDA) test methods ESD/JEDEC JS-001 for the HBM event, and ESD S5.3.1 for the CDM event. HBM and CDM are not directly comparable due to the differences in their event characteristics (voltage, current, time, and energy). CDM Class C1 and C2 are both considered Ultra-Sensitive within the context of this document.

a. An ESD sensitivity level shall be identified for all ESDS applicable hardware by model and level

(e.g. “HBM Class 1A”; “CDM Class C1”).

b. Inspection reports, travelers and/or other paperwork accompanying the hardware shall identify the

ESD sensitivity level at minimum, as well as applicable cautionary notes.

Table 4-1: ESDS Item Sensitivity Classifications

GSFC EPA Control Level ESD Sensitivity Voltage Range

Ultra-Sensitive

CDM C1 <125 V

CDM C2 125 V to <250 V

HBM w/ Breakdown Energy ≤ 0.3 μJ <125 V

HBM Class 0 HBM 0 125 V to <250 V

HBM Class 1A HBM 1A 250 V to <500 V

Note: HBM and CDM sensitivity levels are not proportional or similar by voltage range. The two models differ by duration and shape of the associated pulse when plotted by Current vs. Time.
