ABB 3BHE014105R0001 5SHX26L4510 5SXE05-0154 IGCT Power Module

Product Overview

The 5SHX 26L4510 (3BHE014105R0001) is an ABB reverse-conducting IGCT power module engineered for high-power, medium-frequency converter systems. The device integrates an IGCT and its antiparallel diode into a single press-pack assembly and operates together with the dedicated gate-drive unit 5SXE05-0154, forming a complete, field-proven switching solution for demanding industrial and traction applications.

This RC-IGCT platform is specifically designed for snubberless operation at switching frequencies below 1 kHz, enabling high efficiency, reduced component count, and excellent long-term reliability in multi-kilovolt converter stacks.

Device Architecture and Operating Principle

The 5SHX 26L4510 employs a reverse-conducting IGCT structure in which the main thyristor and free-wheel diode share a common press-pack housing. This configuration minimizes internal stray inductance, enhances thermal symmetry, and supports extremely fast and stable turn-off behavior without external snubber networks.

The matching gate-drive unit 5SXE05-0154 delivers high peak gate currents required for IGCT operation while continuously monitoring device status. Integrated protection and feedback signals allow seamless coordination with higher-level converter control systems.
