Overview
The IXYS CS19-12HO1 is a Silicon Controlled Rectifier (SCR) housed in a TO-220 through-hole package. It features a rated repetitive off-state voltage of 1200 V and an average on-state current of 19 A. The device supports a surge current rating of 180 A with a maximum gate trigger current of 28 mA. Operating within a temperature range from -40°C to +125°C, it exhibits a peak on-state voltage of 1.6 V and a holding current of 50 mA. This component is designed for robust power switching applications requiring reliable latching behavior.
Feature Summary
- High-voltage blocking capability suitable for demanding power circuits
- Robust surge current handling for transient protection scenarios
- Standardized three-terminal control interface for simple drive integration
Applications
- Industrial motor control systems
- Power supply rectification stages
- Heating element regulation circuits
Procurement Notes
Verify the exact suffix designation against official manufacturer documentation to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status via the specific datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a 1200 V blocking voltage and 19 A continuous current are required in a standard TO-220 form factor. Ensure the gate drive circuit can supply at least 28 mA to guarantee reliable triggering. Verify that the thermal management design accommodates the junction temperature limits during operation.
Part Context
This SCR belongs to the IXYS CS series, which focuses on general-purpose thyristors for industrial and commercial power electronics. The series offers various voltage and current ratings packaged in standard through-hole formats to facilitate easy integration into existing PCB layouts and heat sink assemblies.
Replacement Considerations
Direct substitutes include other 1200 V, 19 A SCRs in TO-220 packages such as those from Littelfuse or Microchip. Verify matching electrical parameters like IGT and VTM before substitution.
