MDD142-08N1B, MDD142-12N1B, MDD142-14N1B are industrial-grade dual diode rectifier modules manufactured by IXYS Corporation (now part of Littelfuse Group), featuring 1 pair series diode configuration, specifically designed for high-power rectification applications. The three models are identical in all electrical and mechanical characteristics except for the reverse repetitive peak voltage, allowing flexible selection based on system voltage requirements.
This series of modules adopts Direct Copper Bonded (DCB) Al₂O₃ ceramic substrate and planar passivated chip technology, providing extremely low forward voltage drop and excellent temperature cycling capability. Its high isolation voltage of 3600V RMS and wide junction temperature range of -40°C to 150°C ensure long-term reliable operation in harsh industrial environments. The product uses international standard Y4-M6 package for easy installation, has passed UL E72873 certification, and is widely used in various industrial power systems.
