1.5KE6.8-1.5KE400A
High-reliability discrete products and engineering services since 1977
1500 WATT TRANSIENT
VOLTAGE SUPPRESSORS
FEATURES Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number. Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix.
Voltages from 6.8 to 400 V Breakdown (VBR)
Suppresses transients up to 1500 watts @ 10/1000 μs (see Figure 1)
