The SANREX DFA100CB160 is a 100A, 1600V diode module engineered for reliable rectification, freewheeling, and snubber circuit duties in high-power industrial applications. Built to SANREX's established module platform, this device delivers robust forward current capacity and high repetitive peak reverse voltage (VRRM) performance in a compact, PCB- or heatsink-mountable package. With low forward voltage drop and strong thermal characteristics, the DFA100CB160 suits both continuous and pulsed-load conditions common in industrial drive and power supply designs.

The DFA100CB160 sees widespread use in AC/DC rectifier front ends, DC bus freewheeling circuits, uninterruptible power supplies, induction heating systems, welding inverters, and regenerative drive platforms. Its 1600V blocking capability provides the necessary voltage headroom for 690V AC line-connected systems where transient overvoltages must be tolerated without device failure. Maintenance engineers replacing failed rectifier modules in legacy variable-frequency drives, crane controls, and elevator drive systems will find this module a direct fit for existing assemblies.

Key Features of the DFA100CB160:

• 1600V repetitive peak reverse voltage (VRRM) for robust margin on 690V AC bus applications
• 100A average forward current (IFAV) rating supporting high-duty-cycle rectification and freewheeling loads
• Low forward voltage drop (VF) minimizes conduction losses and reduces heatsink thermal requirements
• Isolated base plate construction allows direct mounting to system heatsinks without additional insulation hardware
• Compact dual-diode module configuration simplifies PCB layout and reduces component count versus discrete diode assemblies
• Designed to SANREX quality standards with high surge current (IFSM) capability for inrush and fault-tolerant operation

The DFA100CB160 has been officially discontinued by SANREX, with any new factory production requiring a 99-week lead time — effectively making spot inventory the only practical source for immediate repair or production needs. Legacy equipment running SANREX diode modules in this current and voltage class is vulnerable to extended downtime if a replacement is not secured in advance. Procurement teams supporting long-lifecycle industrial machinery should treat available stock as a strategic acquisition opportunity. ATI Accurate Technology specializes in exactly these hard-to-find, obsolete, and long-lead-time power semiconductor situations.

ATI Accurate Technology is located in Palmetto, Florida and stocks IGBTs, diodes, thyristors, and rectifier modules from leading manufacturers — including obsolete lines.
