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.

Before placing an order, verify the exact model number and package configuration match your application requirements. Confirm that the thyristor’s voltage and current ratings include safety margins for your load profile. Request the original Eupec datasheet for each model, as specifications vary even within similar series. Do not assume interchangeability without electrical testing under real operating conditions.
Lead time is not stated and must be confirmed per model. Most orders ship within 7 to 14 days if in stock. Incoterms are typically FOB Chengdu, but CIF or DAP may be arranged. Payment is usually via T/T in advance or LC at sight. Packaging is dry-sealed with desiccant and anti-static foam. Always request a packing list with model and serial codes for customs clearance.
Perform incoming inspection using a curve tracer to validate Igt, Vtm, and leakage current. Check for physical damage, correct labeling, and proper lead finish. Ensure the thermal interface material matches the datasheet recommendation. Retain sample units for future reference. Request a certificate of conformance with test data for each batch, especially if used in safety-critical systems.
