What is the voltage range for a class 3 ESDS device?

The voltage range for a class 3 Electrostatic Discharge Sensitive Device (ESDS) is indeed 4-16 kV. This classification is based on the susceptibility of these devices to damage from electrostatic discharge. The class 3 designation indicates that the device is more sensitive to ESD than classes 1 and 2, which are rated for lower voltage ranges.

Devices in the 4-16 kV range can be damaged by relatively low levels of electrostatic discharge, making it critical to handle them with care and to utilize appropriate ESD protection measures. Understanding the voltage range is essential for ensuring that proper precautions are taken during manufacturing, handling, and testing to prevent damage.

In contrast, the other voltage ranges pertain to different classes of ESD sensitivity. For example, class 1 devices are designed to be more resilient against electrostatic discharges, indicating that they can withstand voltages lower than 4 kV before risk of damage, while classes above 3 suggest a higher risk and sensitivity. This knowledge is crucial for individuals working with sensitive electronic components in avionics and other fields where ESD-related failures can occur.
