ABB 3BHB018160R0001 / 5SHY4045L0001 Asymmetric IGCT Power Module – Genuine ABB

Product Overview

The ABB 5SHY4045L0001​ is a high-power asymmetric Integrated Gate-Commutated Thyristor (IGCT) and a member of ABB’s 5SYA1233 data-sheet family. In the ABB 5SHY4045L0001, the power semiconductor is combined with an integrated low-inductance gate unit in a single press-pack assembly, so the device functions as a complete high-current switch rather than as a bare thyristor chip. Its role is to turn multi-megawatt DC-link power into controlled AC for medium-voltage motor drives, or to act as the controlled switching element in rectifiers, inverters and other high-power converter equipment.

The electrical identity of the ABB 5SHY4045L0001​ is built around a 4500 V repetitive off-state blocking rating and a 4000 A maximum controllable turn-off current. These ratings place the device in ABB’s 91 mm IGCT class and make it suitable for series-connected power stacks in medium-voltage converters. Because the device is asymmetric, it is optimised for applications in which forward blocking and controlled turn-off are the principal requirements; it should not be treated as a symmetric four-quadrant switch without checking the converter topology and the official documentation.

The ABB 5SHY4045L0001​ uses press-pack construction for double-sided thermal contact and is intended for forced liquid cooling. This gives the device a well-defined mechanical and thermal interface to the power stack and avoids the bonded-interconnect fatigue mechanisms associated with some conventional module packages. The model supplied here carries the customer ordering reference 3BHB018160R0001. Note that ABB’s 5SYA1233-02 documentation references the ordering code 3BHB018162R0001; the difference should be verified against the physical board or device label, the power-stack drawing and the drive’s bill of materials before ordering or fitting a replacement.
