Overview
The IXYS CS20-16IO1 is a silicon controlled rectifier (SCR) designed for high-power switching applications. It features a rated repetitive off-state voltage of 1.6 kV and an RMS on-state current of 31 A within the TO-247-3 package. The device exhibits a maximum gate trigger current of 80 mA at 1.3 V, with a forward voltage drop of 1.23 V. It supports a maximum working temperature of +150°C and operates down to -40°C. Key electrical characteristics include a holding current of 100 mA and a leakage current of 2 mA under rated voltage conditions.
Feature Summary
- High voltage blocking capability suitable for demanding power electronics environments
- Robust thermal performance allowing operation up to 150°C junction temperature
- Standardized TO-247-3 through-hole mounting for efficient heat dissipation
Applications
- Industrial motor control systems requiring high voltage isolation
- Power supply circuits utilizing thyristor-based regulation
- General purpose AC/DC conversion stages in heavy machinery
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer marking with official IXYS documentation. Ensure the specific suffix matches the required voltage rating. Confirm RoHS compliance status through the latest datasheet revision. Validate that the TO-247-3 pinout aligns with the target PCB footprint design before finalizing orders.
Selection Notes
Select this component when a 1.6 kV blocking voltage is mandatory for the circuit topology. The 31 A RMS current rating determines the thermal management requirements for the heatsink interface. Evaluate the 80 mA gate drive capability against the available control signal strength. Consider the TO-247-3 package constraints regarding board space and mounting hardware compatibility.
Part Context
This SCR belongs to the IXYS CS20 series, which focuses on medium-to-high power thyristor solutions. The series provides standardized packaging for industrial reliability. The 1600V variant specifically addresses applications needing higher voltage margins than lower-rated counterparts in the same family.
Replacement Considerations
Direct substitutes must match the 1.6 kV voltage rating and TO-247-3 package. Verify equivalent current handling and gate trigger specifications. Cross-reference pinouts to ensure anode, cathode, and gate alignment without circuit modification.
