SKKT460 SKKH460 Thyristor Diode Module

The SKKT 460 / SKKH 460​ as high-performance, highly reliable industrial-grade power modules. Their robust current-handling capability, high insulation strength, and durable construction make them ideal for medium-to-high power industrial drives, power supplies, and control systems.

Key Features & Capabilities

1. High Power Handling:​ The modules can handle an average on-state current of 460 Amperes, with peak surge currents reaching tens of thousands of amperes, making them suitable for heavy-duty industrial use.

2. Voltage Ratings:​ Two main voltage classes are available: 1600V​ and 2200V, to suit different operational voltage requirements.

3. Advanced Insulation:​ The module features a ceramic insulated metal baseplate (using Aluminium Nitride), ensuring high electrical isolation between the internal circuitry and the external heatsink for safety and reliability.

4. High Reliability:​ The use of precious metal pressure contacts (instead of solder) enhances reliability by making the module more resistant to thermal cycling and power stress.

Typical Applications

These modules are workhorses in industrial settings, commonly found in equipment such as:

• AC Motor Soft Starters:​ For smoothly starting large AC motors to prevent high inrush currents.

• Input Converters for AC Drives:​ Used in variable frequency drives for motor speed control.

• DC Motor Control:​ e.g., in machine tools for precise speed regulation.

• Industrial Temperature Control:​ e.g., for ovens and chemical processes.

• Professional Lighting Dimming:​ For high-power lighting systems in studios and theaters.
