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.
