Power Semiconductor Diode Modules include one or more power diodes and, in some cases, other power semiconductor devices. Diode module packages are electrically isolated, and usually include metal base-plates (sometimes copper) and a DCB Alumina substrate (Al2O3 Insulator). Power Semiconductor Diode Modules have high thermal efficiency, which assures long life and reliable performance. These modules come with voltage ratings typically between 200 – 1,600 volts (available up to 6,500 volts) and current ratings from 10 – 2,500 amps. Many of these Diode Modules are UL Recognized and RoHS-compliant.
Applications for Diode Modules include Bridge Circuits (single-phase and three-phase), AC-DC Motor Drives, Battery Chargers, Power Supplies, Large IGBT Front End Circuits, Lighting Control, Heat/Temperature Controls (for large commercial ovens, chemical processes, etc.), Motor Drives, and Industrial Welders.
Specific attributes which are important in selecting the right Diode Module for your application include: Configuration – 3 Phase Bridge Rectifier, Antiparallel Pair (unconnected), Diode Phase Leg, Dual Parallel Diodes, Dual Common Anode, etc. (many more configurations available); Voltage Rating (V); Current Rating (A); and Package Type. Our Diode Modules feature a wide range of industry-standard package types.
