The IXYS VUB120-16NOXT is a three-phase bridge rectifier module combining a diode front-end rectifier bridge with a fast-recovery or braking chopper configuration in a single isolated package. Rated at 120A and 1600V, this module is built for high-voltage AC-to-DC rectification in continuous-duty industrial environments. The isolated base construction simplifies thermal management on heatsinks, while the robust IXYS packaging provides low thermal resistance and reliable solder-joint integrity under thermal cycling. It is the preferred choice when engineers need a dense, field-proven rectifier solution that minimizes external component count.

The VUB120-16NOXT is widely deployed in variable frequency drives (VFDs), servo drive front ends, regenerative DC bus systems, elevator drive converters, and industrial UPS input stages where 1600V blocking capability provides the necessary margin on 480V and 690V three-phase lines. Its integrated module topology reduces PCB real estate and assembly labor compared to discrete diode assemblies, making it equally valuable in new OEM equipment designs and as a direct drop-in replacement during field repairs on legacy drives from major manufacturers. Welding equipment rectifiers and traction power supplies also leverage this platform for sustained high-current operation.

Key Features of the VUB120-16NOXT:

• 1600V repetitive peak reverse voltage (V_RRM) provides robust transient margin on 480V and 690V three-phase input lines
• 120A average output current rating supports continuous-duty rectification in high-power industrial converter stages
• Isolated copper base plate enables direct heatsink mounting without additional insulation hardware, simplifying thermal stack-up
• Integrated three-phase bridge topology reduces external component count, board space, and assembly complexity versus discrete diode builds
• Low forward voltage drop minimizes conduction losses and heat generation at full rated current, extending thermal life
• IXYS NOXT package platform offers consistent pin-out compatibility for straightforward replacement of same-family predecessor modules in legacy equipment

With a current factory lead time of 99 weeks, the VUB120-16NOXT is one of the most difficult active IXYS modules to source through standard distribution channels. Production line shutdowns or unplanned field failures cannot wait two years for replenishment. Procurement teams managing MRO inventories for drive-heavy facilities, OEM service depots, and repair shops are increasingly turning to specialized distributors to bridge that gap. ATI maintains stock of obsolete, long-lead-time, and hard-to-find power semiconductors precisely for these situations — providing new OEM product when the factory queue is measured in quarters, not days.
