The SANREX DFA50BA160 is a high-voltage diode module rated at 50 amperes and 1600 volts, built for demanding rectification and freewheeling applications in industrial power electronics. As a double-diode configuration module, it delivers reliable forward conduction and reverse blocking performance in a compact, thermally efficient package. The 1600V voltage class provides necessary headroom for line-connected and inverter-based systems where transient overvoltages are a routine design concern. Engineers specifying or replacing this module will find it a direct fit for legacy SANREX-based power assemblies.

The DFA50BA160 is commonly found in AC/DC converters, motor drive front-end rectifiers, uninterruptible power supplies, welding equipment, and industrial heating systems. Its 1600V blocking capability makes it well-suited for three-phase rectifier bridge assemblies operating from high-line AC sources. Field replacement of this module is critical in maintaining uptime for older capital equipment where the original design is no longer supported by the OEM. Applications in crane drives, lift systems, and process control power supplies frequently rely on SANREX diode modules of this class for long-term serviceability.

Key Features of the DFA50BA160:

• 50A average forward current rating suitable for mid-range industrial rectifier assemblies
• 1600V repetitive peak reverse voltage (VRRM) providing robust transient margin in high-line applications
• Double-diode module configuration enabling compact bridge or freewheeling circuit integration
• Isolated baseplate construction for direct heatsink mounting without additional insulation hardware
• Low forward voltage drop minimizing conduction losses and reducing thermal management requirements
• Industry-standard SANREX module footprint simplifying direct drop-in replacement in existing equipment

The DFA50BA160 carries an obsolete status with a 99-week factory lead time, meaning new production orders from SANREX are not a viable option for maintenance or emergency replacement scenarios. For procurement teams managing MRO inventories or engineers facing unplanned downtime, waiting nearly two years for a factory order is not operationally acceptable. ATI Accurate Technology specializes in exactly this situation — stocking hard-to-find, long-lead-time, and obsolete power semiconductors so your equipment stays running without extended delays. Verifying stock levels early and securing spares before the next failure event is strongly recommended for any facility running systems that depend on this module.

ATI Accurate Technology is located in Palmetto, Florida and ships same-day on orders received before 5PM EST. We stock IGBTs, thyristors, diodes, and rectifier modules including obsolete and allocated parts that are difficult to source elsewhere. Volume pricing is available for MRO stocking orders.
