Import Eupec Thyristors — Buy in Bulk from Supplier in China

A&S Thyristor Co., Ltd. supplies original Eupec high-power thyristors and diodes, including models such as D2209N22T, T1451N, D798N16TOF, T218N16TOF, T358N16TOF, T588N16TOF, and T1189N18TOF. These devices are designed for industrial switching applications with voltage ratings up to 1600V and current ratings up to 1189A, compliant with IEC 60747-6 standards. All units are sourced as genuine Eupec components, not rebranded or remanufactured.

The thyristors feature silicon PNPN junctions with glass passivation, standard for high-reliability industrial use. Typical thermal resistance values range from 0.05 to 0.15 K/W depending on package type, and gate trigger current (Igt) varies between 20mA and 150mA across models. Packaging includes TO-200AB, TO-200AC, and disc-type configurations with copper-clad substrates for efficient heat dissipation in high-current environments.

These components are used in motor drives, welding equipment, induction heating systems, and power regulators by industrial OEMs and maintenance suppliers. Buyers typically order in quantities of 10 to 50 units per model. Packaging is anti-static, dry-sealed with desiccant, and shipped in bulk trays or tubes. Lead time is confirmed upon order, and delivery terms are negotiable under FOB Chengdu or CIF terms.

A&S Thyristor Co., Ltd. is based in Chengdu, Sichuan, China, and operates as an authorized distributor of original Eupec, ABB, Infineon, and other major semiconductor brands. The company specializes in industrial-grade power semiconductors and maintains inventory of discontinued and hard-to-source thyristor models. Their listing indicates an imported supplier tier and harbor trust status, but no manufacturing capability is claimed. No revenue figures, employee count, or client list are provided or implied.

The supplier responds to inquiries within one working day, though no formal verification badges or certifications are displayed. They do not claim to manufacture components but state they distribute original devices with traceable provenance. All products are sourced from established channels, and model availability is confirmed upon request. The company does not offer custom modifications or retesting services.
