Overview
The CS23-12IO2 is a phase control thyristor manufactured by IXYS, designed for high-voltage applications. It features a maximum repetitive peak reverse voltage of 1200V and a maximum on-state current of 50A. The device utilizes a TO-208AA (TO48) package with screw mounting capabilities. Key electrical characteristics include a maximum gate trigger voltage of 2.5V and a holding current of 100mA. Operating temperatures range from -40°C to +150°C junction temperature.
Feature Summary
- Phase control thyristor design optimized for AC power regulation
- Robust TO-208AA screw-mount package for secure installation
- High voltage blocking capability up to 1200V
- Defined gate triggering parameters for reliable switching
Applications
- Industrial motor speed control systems
- AC power supply phase angle control circuits
- Solid-state relay applications requiring high voltage isolation
- Heating element control in industrial equipment
Procurement Notes
Verify the exact datasheet version from IXYS or authorized distributors to confirm mechanical dimensions and thermal characteristics. Ensure the TO-208AA footprint matches your PCB or chassis design. Confirm that the 50A continuous current rating aligns with your system's thermal management strategy under actual operating conditions.
Selection Notes
Select this component when a 1200V blocking voltage and 50A current capacity are required in a standard stud-mount configuration. Consider the 2.5V max gate trigger voltage for driver compatibility. Evaluate thermal resistance requirements based on the TO-208AA package size and expected duty cycle compared to alternative modules.
Part Context
This part belongs to IXYS's phase control thyristor series, distinct from their fast recovery diodes or IGBT modules. The CS23 series is specifically engineered for line-frequency AC control applications, differing from high-speed switching devices used in DC-DC converters or inverters.
Replacement Considerations
Direct substitutes may include other 1200V/50A TO-208AA thyristors from manufacturers like Littelfuse or Semikron, provided pinout and thermal specifications match. Verify equivalent dv/dt ratings and gate charge characteristics before substitution.
