CS20-14IO1

Scrs Overview

The CS20-14IO1 is a single phase control thyristor manufactured by IXYS, designed for line frequency applications. It features a 1400 V repetitive peak off-state voltage and a 20 A average on-state current rating. The device utilizes a planar passivated chip structure housed in an isolated TO-247AD (ISOPLUS) package with three terminals. Key electrical characteristics include a maximum DC gate trigger current of 65 mA and a holding current of 100 mA. It supports a non-repetitive peak on-state current of 220 A and offers a critical rate of rise of off-state voltage of 1000 V/µs.

Scrs Feature Summary

• Planar passivated chip design ensures long-term stability of blocking currents and voltages
• Isolated mounting screw hole allows for easy installation without additional insulators
• Complies with international JEDEC standards for the TO-247 package form factor

Scrs Applications

• Motor control systems
• Power converter circuits
• AC power controllers
• Switch-mode and resonant mode power supplies
• Light and temperature control devices

Scrs Procurement Notes

Verify the specific suffix IO1 to confirm the 1400 V voltage class and ISOPLUS packaging variant. Ensure the ordering code matches the exact manufacturer designation from IXYS or Littelfuse documentation. Cross-reference the JEDEC package outline to guarantee mechanical compatibility with existing heatsink interfaces and PCB layouts.

Scrs Selection Notes

Select this component when a 1400 V blocking capability is required alongside a 20 A continuous current rating. The TO-247AD package provides robust thermal performance for high-power density designs. Consider the 65 mA gate trigger requirement for driver circuit sizing. Verify that the application operates within the specified line frequency range for optimal switching performance.

Scrs Part Context

This part belongs to the IXYS CS20 series of single thyristors, which shares common architectural features across different voltage ratings. Variants such as CS20-12IO1 and CS20-16IO1 offer 1200 V and 1600 V ratings respectively, maintaining identical current handling and package dimensions. This standardization simplifies inventory management for designs requiring different voltage margins.

Scrs Replacement Considerations

Direct substitutes include other IXYS CS20 series variants like CS20-12IO1 or CS20-16IO1 if voltage ratings permit. Generic replacements must match the TO-247AD footprint, 20 A current rating, and 1400 V blocking voltage. Verify gate trigger specifications and thermal resistance values before substituting with components from other manufacturers.
