Rugged ESD Demonstration

The LTM2885 µModule isolator is subjected to repeated ESD strikes as high as 20kV. The line driving bus pins, as well as the isolation barrier, are all extremely rugged to high energy ESD pulses. This video also illustrates that the LTM2885 and its RS485 Transceiver continue to operate through the ESD events. Not only is the device undamaged, but its isolated and differential data integrity is maintained during the electrostatic discharge. The video illustrates Human Body Model ESD up to 20kV as well as higher energy IEC cable discharges up to 8kV. Notice the air discharge sparks jumping a 15mm gap. These ESD zaps are more painful if striking the operator than they are to the LTM2885.
