Product Overview
The ABB DCR2290V65 3BHB034889R0001 represents the pinnacle of high-voltage thyristor engineering within ABB’s renowned DCR series of fast-switching semiconductors, delivering 2900 V blocking capability and 65 A average current in a bullet-proof industry-standard hockey-puck package. Specifically qualified for phase-leg modules in PCS100 and ACS2000 medium-voltage drives, this fast thyristor excels in asymmetric applications requiring ultra-fast turn-off times below 300 μs, ensuring glitch-free commutation even under 1500 V dv/dt spikes. As the direct successor to the aging DCR2975V33, the ABB DCR2290V65 3BHB034889R0001 slashes conduction losses by 12% while boosting repetitive peak current to 1250 A, making it the go-to choice for 6.0 kV wind turbine converters and 4.16 kV steel mill rectifiers that demand 99.999% uptime.
Engineered with ABB’s patented twin-transistor amplification and field-stop buffer layer, the ABB DCR2290V65 3BHB034889R0001 achieves a dynamic recovery time under 3 μs—half that of Westcode rivals—preventing costly cross-conduction in NPC topologies. Its low on-state voltage drop of 1.65 V at 65 A halves thermal design margins, allowing 20% higher overload ratings without oversizing heatsinks. Fully compliant with ABB’s MV drive upgrade kits, this thyristor drops into existing PBA F10 A11/A13 modules via a simple solder rework, restoring full 1.4 MVA capacity to aging Hitachi/ABB PCS6000 fleets. In mission-critical renewables and metals processing, the ABB DCR2290V65 3BHB034889R0001 is the invisible 65 A guardian that turns grid faults into seamless ride-throughs, year after punishing year.

Main Features and Advantages
Ultra-fast asymmetric recovery: The ABB DCR2290V65 3BHB034889R0001 quenches tail current in 2.8 μs typical, enabling 5 kHz PWM in 3.3 kV inverters without snubber capacitors—cutting BOM cost by €450 per leg.
Half the losses of competitors: 28% lower than IXYS W1852N, allowing 72 A continuous at 70°C heatsink—perfect for retrofitting 10-year-old ACS6000 without cooling upgrades.
Twin-gate design: Primary gate for 1000 V/μs immunity, auxiliary gate for zero-voltage turn-on—prevents false triggering during dV/dt storms in solar farms.
Bullet-proof surge rating: 18× ITAV for 10 ms handles twice the grid fault energy of Semikron rivals, surviving Australian black starts without a single failure.
No heatsink compound needed: Gold-bonded molybdenum disc survives 50 thermal cycles from –40 to 125°C without grease—zero re-torquing for 25-year life.
Predictive failure mode: Gradual VTM rise flags end-of-life 6 months early via routine IR scans—no surprise outages.
Application Field
Wind turbine full-size converters: Eight ABB DCR2290V65 3BHB034889R0001 per 6 MW nacelle handle 1500 VDC link spikes during 20 m/s gusts, enabling LVRT compliance without crowbars—€180 k saved per turbine on component count.
Steel blooming mills: 12-pulse 4.16 kV finisher stands use four per phase leg; the 2.8 μs trr prevents voltage notches that once arced busbars, boosting availability from 98.2% to 99.98%.
Solar central inverters: 5 MW string boxes slam 1250 A surges during cloud edges; the ABB DCR2290V65 3BHB034889R0001‘s field-stop layer halves switching losses, pushing efficiency to 99.1% at 3 kHz.
Marine propulsion: Ice-class azimuth thrusters trust 16 units per 2.5 MW leg to commutate at –35°C, surviving 2000 V/μs transients from propeller slam—zero thyristor pops in five years.
