6 FAQs about [Solar container esd electrostatic test]

What is electrostatic discharge (ESD) on a solar array?

ISO 11221:2011 details that Electrostatic Discharge (ESD) on a solar array is “a single, fast, high-current transfer of ESD that results from a strong electrostatic field between two objects in close proximity.” Differential charging on solar array exterior surfaces builds up an electric charge on the insulator surface.

What is electrostatic discharge (ESD)?

Electrostatic Discharge (ESD) remains a threat to the integrity of electronic hardware in space despite extensive NASA and industry experience with controlling ESD and its effects. It can cause various detrimental effects to the designated space operation.

How does ESD affect a spacecraft?

As ESD can occur repeatedly during the lifetime of a spacecraft, there can be cumulative effects such as surface degradation, surface contamination via vaporized material, or internal damage to solar cells due to surge voltages.

Why is electrostatic discharge a major concern of spacecraft technology?

Electrostatics is a major concern of spacecraft technology. Since space is filled with hot and low-density plasma that builds up high differential voltages, electrostatic discharge (ESD) can occur. ESD may sometimes cause an anomalous behavior of spacecraft electronics.

Does ISO 11221 help control ESD in space?

Designers of ESD-sensitive devices and handlers of ESD-sensitive equipment should not assume that routine ESD engineering principles and practices will continue to be adequate to prevent damage to flight equipment. Although, adhering to ESD testing standards like ISO 11221:2011 do help in controlling ESD in space. What Is ISO 11221?

Is the diode design type more or less susceptible to ESD stress?

It has been suggested that it is not necessarily the diode design type that determines if the diode is more or less susceptible to ESD stress, but instead a result of quality control of the manufacturing. For example, the process may be as follows: a diode as the 15SQ100 (not tested herein) is being checked in quality control after manufacturing.
