ABB 5SHY4045L0004 IGCT Module | 4500V, 91MM 3BHB021400R0002
Product Overview
5SHY4045L0004 belongs to ABB HiPak series press-pack IGCT (Integrated Gate Commutated Thyristor), with ABB part code 3BHB021400R0002. It adopts 91mm chip package size and 4500V rated blocking voltage. It is an asymmetric IGCT developed by ABB for high-power medium-voltage power conversion. Integrated with gate drive unit and built in Press-Pack press package, it serves as the core power switching device for high-power converter valves and medium-voltage drive units.
IGCT is a high-power semiconductor upgraded by ABB based on GTO. It retains the advantage of low conduction loss of thyristor while realizing gate-controlled hard turn-off without bulky snubber circuits (snubberless turn-off). It greatly simplifies the hardware structure of high-power converters and improves system power density. This device comes with factory-integrated gate unit and adopts optical fiber signal drive isolation to electrically separate high voltage and control loops, suitable for megawatt-level high-power conversion scenarios.

Core Product Features
- Press-pack double-sided heat dissipation: Press-Pack package enables heat dissipation from both top and bottom surfaces, with much higher heat dissipation efficiency than single-sided substrate modules. The device fails in short-circuit mode without explosion risk. It has explosion-proof design and high safety when connected in series in high-voltage valve stacks.
- Integrated gate unit + fiber optic drive: Gate driver board is integrated with IGCT body. Switching signals are transmitted via optical fiber to fully isolate strong and weak electricity, delivering strong anti-electromagnetic interference capability for high-voltage heavy electromagnetic environments.
- Low conduction loss: Low on-state voltage drop under large current reduces continuous conduction loss and the load of cooling system, suitable for long-term continuous high-power operation.
- Snubberless turn-off capability: It supports direct hard turn-off without snubber capacitors or buffer circuits, simplifying converter topologies, cutting component quantity, improving overall reliability and lowering maintenance cost.
- Wide temperature range & high reliability: It can start at -40℃ with maximum junction temperature of 125℃ and strong load cycle tolerance, adapting to harsh industrial environments such as mining, metallurgy and offshore applications.
Application Scenarios
- Medium & high voltage high-power drives: Main drives for rolling mills, mining ball mills / semi-autogenous mills, large compressors, fans and water pump medium voltage frequency converters
- Grid power quality equipment: STATCOM/SVG static synchronous compensator, SVC static var compensator, grid stabilization devices
- New energy & power transmission: Full power converters for large wind turbines, energy storage PCS, VSC-HVDC converter valves
- Other high-power applications: Marine electric propulsion, four-quadrant converters for pumped storage units, large metallurgical electrolysis power supplies, high-power drives for oil & gas industry
Operation Notes
- Uniform clamping force must be applied to the device in accordance with ABB specifications. Insufficient clamping pressure will increase thermal resistance and cause overheating damage to the device.
- Water cooling is preferred; derating is required for air cooling working conditions.
- Gate power supply and fiber optic links must be designed per original manufacturer documents. Fiber bending radius and signal timing have strict requirements.
- Multiple devices can be connected in series or parallel for capacity expansion, but voltage sharing and current sharing design must be strictly implemented following ABB HiPak series connection specifications.

Frequently Asked Questions
Q: What is the relationship between 5SHY4045L0004 and 3BHB021400R0002?
A: They refer to the same device. 5SHY4045L0004 is the device model, and 3BHB021400R0002 is ABB material order code. Both numbers can be used for searching during procurement and spare part replacement.
Q: What are the advantages of IGCT compared with IGBT?
A: IGCT has lower on-state loss and higher surge current withstand capability. The press-pack package has safe short-circuit failure mode, making it more suitable for megawatt-level high-voltage valve stacks. IGBT has advantages in medium-low power and high-frequency applications.
Q: Does this IGCT come with built-in freewheeling diode?
A: This model is asymmetric IGCT without integrated freewheeling diode. Separate matching fast recovery diodes are required for high-power inverter topologies.
Q: What cooling method is recommended for 5SHY4045L0004?
A: Liquid water cooling is the primary recommended cooling solution for full rated operation. Air cooling can only be used under low load conditions (<30% rated load).
