GENERAL PURPOSE RECTIFIER DIODE

3500 Amperes 4200 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

APPLICATIONS:

DC Power Supplies

ORDERING INFORMATION Input Rectifiers

Plating Supplies
Select the complete 12 digit Part Number using the table below.
EXAMPLE: RBS84235XXOO is a 4200V-3500A General Purpose Diode
with a typical reverse recovery time of 25µs.
