      FAQs

      What is the difference between Diode Modules, Thyristor Modules, Stud, and Disc types?

      Diode Modules and Thyristor Modules are compact, easy-to-mount packages suited for most industrial control boards and assemblies. Stud Thyristors are single-device packages designed for high-current applications with heatsink mounting. Disc Thyristors (also called capsule type) are used in the highest power applications, clamped between heatsinks for maximum thermal performance.

      I'm not sure which product fits my application — can you help?

      Absolutely. Tell us your application (e.g. induction heating, motor drive, electroplating), working voltage, and current requirements — our engineers will recommend the right diode or SCR type and package for you.

      Can I send you a photo or datasheet of my existing part to find a replacement?

      Yes — just send us a photo, nameplate data, or datasheet via WhatsApp or email. Our engineers will identify the equivalent or compatible replacement for you within 24 hours.

      Can you provide test reports or certifications?

      Yes. Our products are CE certified and manufactured under ISO 9001 quality management standards. Test reports are available upon request for each batch.

      What information do I need to provide for a custom or OEM/ODM order?

      Please provide your required voltage and current ratings, package type, quantity, and any special requirements such as high-temperature versions or custom packaging. For ODM requests, please share your specifications or drawings. Our team will respond with a solution within 24 hours.

      What is the lead time and MOQ?

      MOQ is typically 1 piece for standard models. Lead time is 3–7 business days for stock items, and 2–4 weeks for custom or large orders. Contact us for specific availability.
