Overview

The ABB IGCT module — represented by part numbers 3BHE014105R0001, 5SHY3545L0020, and 5SXE05-0154 — is a high-power semiconductor switch designed for demanding industrial power conversion. As part of ABB’s Integrated Gate-Commutated Thyristor family, it provides the robustness of a press-pack GTO with the high-speed turn-off capability typically associated with IGBTs.

Supporting snubberless operation, the module enables simpler and more compact converter topologies in medium-voltage drives, traction propulsion, and grid-connected power electronics. Its asymmetric configuration allows efficient handling of unidirectional conduction with bidirectional voltage blocking, ideal for multi-level converter stacks.

Engineered for harsh electrical and thermal environments, the IGCT maintains high reliability under cyclic loading, making it well suited for long-lifecycle industrial applications.

Technical Data

Typical Applications

This IGCT module is widely deployed in:

• Medium-voltage drives (steel rolling mills, compressors, mining systems)

• Traction and locomotive propulsion (regenerative braking & propulsion)

• HVDC and FACTS converters in transmission networks

• Offshore wind & renewable grid interfaces

• Marine propulsion and large drives in ship systems

Its high current capability and fatigue-resistant construction offer long-term performance in converters subject to continuous switching and vibration.

Therefore, the ABB IGCT module is a key enabler of high-efficiency, high-reliability power conversion across modern industrial and energy infrastructures.

FAQ

Q: What are the electrical ratings?
4500 V and 4000 A continuous current capability.

Q: Why select IGCT over IGBT?
Higher efficiency, lower conduction loss, and snubberless switching with thyristor-grade robustness.

Q: Can it be stacked for higher power?
Yes — mechanical press-pack design supports series and parallel operation in multi-level converters.

Q: What cooling is required?
Air or liquid cooling depending on the drive/converter design.

Q: What is required for the gate interface?
A fast, isolated IGCT gate unit that ensures rapid current extraction during turn-off.
