A&S Thyristor Co., Ltd. distributes a full line of ABB power thyristors, including bi-directional controlled thyristors (BCT), gate turn-off asymmetric standard thyristors, fast thyristors, integrated gate-commutated thyristors (IGCT), and GTO thyristors. The catalog spans models such as ABB 5SGA 40L4501, 5STB 24Q2800, 5STP 18H3600, 5STP 45QXXXX, and T989-3300XX, covering voltage classes from 1.8 kV to 4.5 kV and current ratings up to 4500 A, as listed in the supplier’s inventory. Each unit is sourced as original ABB stock, with no aftermarket modifications.
These devices are built on silicon wafer substrates with typical diameters of 100 mm to 150 mm for high-power applications, offering standard blocking voltages in the 2 kV to 6 kV range and typical on-state voltage drops of 1.2 V to 2.5 V. The thyristors are designed for industrial converters, HVDC transmission, and motor drives, conforming to standard IEC 60747 and typical industry practices for thermal cycling, surge current (ITSM), and di/dt ratings. A&S Thyristor Co., Ltd. provides these components in press-pack, module, or stud-base housings, depending on the model.
Industrial buyers use these thyristors in medium and high-voltage drives, static VAR compensators, and traction applications where precise phase control and high reliability are critical. The supplier supports bulk orders and can source additional ABB models on request, with technical data sheets and compatibility verification available. Buyers should confirm exact voltage, current, and switching frequency requirements for their systems, as well as packaging preferences for integration into existing racks or custom assemblies.

Before ordering, verify the exact part number compatibility with your system’s voltage, current, and switching frequency requirements. Cross-reference the model’s datasheet to confirm electrical characteristics such as on-state voltage drop, ITSM, and di/dt ratings, as these directly impact performance and longevity in your application.
Confirm the preferred housing type (press-pack, module, or stud-base) and packaging options for your order. Discuss Incoterms such as FOB, CIF, or DDP with the supplier, and clarify payment terms, which may include T/T or other methods. Lead times for standard models are typically short, but custom or less common parts may require additional sourcing time.
Request a certificate of conformity and test reports for the thyristors to ensure they meet IEC 60747 standards. For critical applications, consider third-party inspection or factory acceptance testing to validate performance under load. Ensure all documentation, including packing lists and compliance certificates, is included with the shipment for customs clearance.
