VIS400 Frequently Asked Questions (FAQs)

A good PCB layout for VIS400 involves keeping the input and output traces separate, using a ground plane, and minimizing the distance between the device and the TVS diodes. It's also recommended to use a common ground point for all components.
While VIS400 is rated for 400A surge currents, it can handle higher currents for shorter durations. However, exceeding the rated current can lead to device degradation or failure. It's essential to ensure that the device is properly sized for the application's surge current requirements.
Yes, VIS400 devices can be used in parallel to increase the surge current rating. However, it's crucial to ensure that the devices are properly matched and that the PCB layout is designed to minimize any differences in current sharing between devices.
The response time of VIS400 is typically in the range of 1-10 nanoseconds. This fast response time helps to protect sensitive electronics from surge damage.
VIS400 is designed to minimize the impact on signal integrity. The device's low capacitance and inductance ensure that high-speed data lines are not compromised, and the signal integrity is maintained.
