The IXYS VUB116-16N01 is a three-phase bridge rectifier module delivering 116A average output current at a 1600V repetitive peak reverse voltage rating. Built around IXYS's proven press-pack-style module construction, this device combines six diodes in a full-wave bridge configuration with an isolated copper baseplate, enabling straightforward heatsink mounting and reliable thermal dissipation. Its robust blocking voltage and current capacity make it a preferred choice wherever high-power rectification with long-term field reliability is required.

The VUB116-16N01 is widely deployed in industrial variable-speed AC and DC motor drives, regenerative braking systems, UPS front-end rectifiers, welding power supplies, and medium-voltage DC bus charging circuits. Its high blocking voltage is particularly valuable in 690VAC line-connected systems common in European and heavy industrial environments, while the 116A current rating supports multi-kilowatt continuous duty cycles without derating under proper thermal management. OEM machine builders and MRO teams alike rely on this module for front-end rectifier stages in servo drive cabinets and crane hoist controllers.

Quick Reference: VUB116-16N01

Key Features of the VUB116-16N01:

• 1600V repetitive peak reverse voltage (VRRM) supports direct connection to 690VAC three-phase mains with adequate transient margin
• 116A average forward current (IFAV) per module, enabling multi-kilowatt continuous rectification in a single compact housing
• Isolated copper baseplate construction allows direct heatsink mounting with no additional isolation hardware on the mounting surface
• Low forward voltage drop across bridge diodes minimizes conduction losses and reduces thermal stress in high-duty-cycle applications
• Industry-standard VUB-series footprint ensures pin-compatible drop-in replacement with equivalent modules from compatible manufacturers
• High surge current capability (IFSM) provides resilience during power-on inrush events in capacitive DC bus topologies

With a factory lead time of 34 weeks on new production, the VUB116-16N01 presents a genuine procurement challenge for maintenance teams facing unplanned downtime or engineers building new systems to schedule. IXYS modules in this voltage and current class are frequently constrained at the distributor level, making warehouse inventory critical. ATI Accurate Technology maintains stock of hard-to-find IXYS rectifier modules precisely to bridge these gaps — whether you need a single emergency replacement or a buffer quantity to protect against future lead-time exposure.
