Component Specifications

Definition
Main terminals (anode/cathode) are critical electrical connection points in Silicon-Controlled Rectifier (SCR) modules, designed to handle high current loads and provide reliable interfaces between the semiconductor device and external power circuits. These terminals facilitate the controlled rectification of alternating current to direct current in industrial applications.
Working Principle
The anode and cathode terminals serve as the primary electrical pathways for current flow through the SCR. When a gate signal triggers the SCR, current flows from the anode to the cathode terminal, enabling power control in AC-to-DC conversion circuits.
Materials
Copper alloy (typically C11000 or C10100) with tin or silver plating for enhanced conductivity and corrosion resistance; insulating materials include ceramic or high-temperature thermoplastics.
Technical Parameters
  • Current Rating 50-1000A
  • Voltage Rating 600-1600V
  • Temperature Range -40°C to +125°C
  • Contact Resistance <0.5mΩ
  • Insulation Resistance >1000MΩ
Standards
ISO 9001, DIN EN 60146

Frequently Asked Questions

What is the difference between anode and cathode terminals in SCR modules?

The anode terminal is the positive input where current enters the SCR, while the cathode terminal is the negative output where current exits after rectification.

How do main terminals affect SCR module performance?

Main terminals directly impact current-carrying capacity, thermal management, and electrical reliability; poor terminal design can lead to overheating, voltage drops, or connection failures.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
