    Matching Power Device: Medium voltage IGCT + fiber optic GDU gate driver board
    Compatible System: Small/medium capacity GE EX2100 Generator Static Excitation Cabinet, ABB ACS6000 MV Drives, Wind Power Grid-Tied Converters
    Type: 800V StakPak Press-Pack Soft Fast Recovery Freewheeling Diode Complete Water-Cooled Stack Assembly
    Core Function: Inductive load freewheeling overvoltage suppression, three-phase rectifier power conversion, modular stack assembly, long-term continuous power plant operation
    1. Product Overview
    5SDF0860H0003 is ABB 800V StakPak press-pack soft fast recovery freewheeling diode, matched with dedicated water cooling mounting frame 3BHL000397P0001 as a complete power stack unit. It is matched with medium voltage IGCT to form full rectifier/inverter bridge arms for medium & small capacity power converters. Hermetic ceramic press-pack housing eliminates internal solder layers, delivering excellent thermal cycling fatigue resistance; the device fails in short-circuit mode to avoid generator loss-of-field runaway risks in power plant excitation systems. Soft recovery characteristic drastically reduces switching reverse recovery losses, lowering cabinet heat generation under 24/7 full load continuous operation. Mainly applied in small/medium unit GE EX2100 static excitation converters, also widely used in wind power grid-connected converters, medium voltage rolling mill & mine variable frequency drives. Integrated water cooling base plate supports 860A continuous rated current stable output. ABB discontinued original new production, refurbished and surplus stacks are mainstream spare parts for power plant maintenance and retrofit.
