4350 Amperes 4000 Volts
Powerex General Purpose Rectifier Diodes are
designed with high blocking voltage capability and
low forward voltage drop to minimize conduction
losses. These are packaged in hermetic, ceramic
Pow-R-Disc packages which can be mounted
using commercially available clamps and
heatsinks or fully assembled to a variety of air or
water cooled heat exchangers.
FEATURES:
Low On-State Voltage
Hermetic Ceramic Package
Excellent Surge and I2t Ratings
APPLICATIONS:
DC Power Supplies
Input Rectifiers
Plating Supplies
