M1.5KE6.8A M1.5KE400CA(e3) Screening in 1500 Watt Unidirectional and Bidirectional reference to Available MIL-PRF-19500 Transient Voltage Suppressor available 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.
