FAQ – Application & Selection Focus

What is the difference between a Diode, SCR, Rectifier Module, and SSR?

Diodes / SCRs – Fast switching, high current handling, precise AC/DC control
Rectifier Modules – Convert AC to DC efficiently with high current ratings
SSR Modules – Silent, mechanical-free switching for industrial automation

How do I choose the correct current and voltage rating?

Diodes / SCRs: 3–5× working current for surge / inductive loads
Rectifiers: ≥ 2× AC line voltage, consider heatsink if >10A
SSRs: Output current ≥ 3–5× load current, add heatsink for inductive / high-power loads

What applications are these components suitable for?

Industrial power systems, heating, motor drives, UPS, automation, welding, electronic controls

Do you provide OEM / ODM customization?

Yes. Current rating, voltage, module type, terminals, enclosure, labeling, and packaging are customizable.

Can you provide datasheets or manuals?

Datasheets and manuals are available on each product page, or contact our technical team for full documentation.

Do you offer technical support?

Yes. Our team provides guidance on component selection, application matching, and installation support.
