DESCRIPTION
These MRT100KP40A MRT100KP400CA high reliability devices protect against dangerous
high-voltage, short term transients such as those caused the the secondary effects of lightning
per IEC61000-4-5 (see protection classes below) and RTCA/DO-160. They also protect
against voltage spikes caused by inductive load switching, induced RFI, and ESD or EFT per
IEC61000-4-2 and IEC61000-4-4. Clamping time is nearly instantaneous at < 5ns.
