1. Product Overview
5SHX2645L0002 is ABB 2600V reverse conducting RC-IGCT press-pack silicon chip, integrated with built-in freewheeling diode inside single wafer, matched with dedicated optical gate driver board 3BHB012961R0002 as a full power stack unit.
Compared with discrete IGCT + external separate diode stacks (5SDF series), this RC integrated design reduces bus stray inductance, simplifies cabinet layout and cuts overall equipment volume. Hermetic ceramic press-pack housing eliminates internal solder layers for outstanding thermal cycling reliability; device fails in short-circuit mode to avoid generator loss-of-field runaway hazards in power plant excitation systems.
Low snubberless switching losses reduce cabinet heat generation under 24/7 full-load continuous operation. Widely applied in medium/small unit GE EX2100 static excitation converters, ABB ACS6000 medium voltage mine & steel mill variable frequency drives, wind farm grid-connected VSC converters. Dual-sided water cooling design supports stable 2645A rated continuous output. ABB discontinued original new production, refurbished and surplus stacks are mainstream spare parts for power plant maintenance and retrofit.
