DESCRIPTION
The popular Transient Voltage Suppressor series of M1.5KE6.8 M1.5KE400CA with its
various upscreening options offer an extended voltage range and provides a wide variety of
commercial, high reliability, RoHS and bidirectional options. All have the same high peak
pulse power rating of 1500 W and extremely fast response time. They can protect from
secondary effects of lightning per IEC61000-4-5 and the class levels as shown below as well
as voltage transients from inductive switching and RFI. Since their response time is virtually
instantaneous, they also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
