P4KE6.8 thru P4KE400CA, e3  
400 Watt Transient Voltage Suppressor  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
This 400 W Transient Voltage Suppressor (TVS) series is an economical  
molded axial-leaded package to protect voltage-sensitive components from  
destructive or partial degradation. They are available in both unidirectional  
or bi-directional configurations as well as RoHS Compliant (annealed  
matte-Tin finish) with an e3 suffix added to the part number. They have a  
peak pulse power rating of 400 watts for a 10/1000 µs as depicted in  
Figures 1 and 2. The nominal breakdown voltages (VBR) in this series  
extend from 6.8 to 400 volts. Microsemi also offers a broad spectrum of  
additional TVSs to meet your needs.  
DO-41  
(DO-204AL)
