GENERAL PURPOSE RECTIFIER DIODE
Powerex, Inc., 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724)925-7272
10,000 Amperes 1200 Volts
Powerex General Purpose Rectifier Diodes are
designed with high locking 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 I
