Overview
The IXYS CS20-12IO1 is a single Silicon Controlled Rectifier (SCR) housed in a TO-247AD ISOPLUS package. It features a rated repetitive off-state voltage of 1.2 kV and an RMS on-state current of 31 A. The device has a maximum forward voltage of 1.23 V, with a gate trigger voltage of 1.3 V and a gate trigger current of 80 mA. It operates within a temperature range of -40°C to +125°C, offering high dv/dt capability and robust surge performance for phase control applications.
Feature Summary
- High thermal efficiency via TO-247AD ISOPLUS three-pin through-hole mounting
- Robust surge current handling for demanding power switching environments
- Sensitive gate triggering characteristics for efficient drive circuit integration
Applications
- Industrial motor speed control systems
- Solid-state relay circuits
- General purpose AC power regulation
Procurement Notes
Verify the specific suffix and marking against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status directly with the supplier or authorized distributor before procurement. Cross-reference the part number with official component databases to avoid counterfeit risks.
Selection Notes
Select this component when a 1200 V blocking voltage and approximately 31 A continuous current are required in a standard TO-247 package. Ensure the gate drive circuit can supply at least 80 mA to guarantee reliable turn-on. Verify that the ambient temperature does not exceed the specified limits without adequate heatsinking.
Part Context
This SCR belongs to the IXYS CS series of high-power thyristors designed for industrial phase control. The CS20-12IO1 variant specifically targets applications requiring 1200 V isolation with moderate current capacity. It serves as a discrete alternative to integrated modules in cost-sensitive power electronics designs.
Replacement Considerations
Consult the official IXYS replacement guide for direct equivalents. Generic replacements must match the 1200 V rating, TO-247 package, and similar gate trigger specifications to maintain circuit performance.
