Overview
The IXYS CS8-12IO2 is a phase control thyristor designed for line frequency applications, featuring a maximum repetitive reverse voltage of 1200 V and an RMS on-state current rating of 25 A. It supports a maximum average forward current of 16 A at a case temperature of 85°C with a 180-degree sine wave conduction angle. The device utilizes a JEDEC TO-64 package with a planar glassivated chip to ensure long-term stability of blocking currents and voltages. Key electrical characteristics include a maximum non-repetitive surge current of 270 A at 8.3 ms (60 Hz) and a critical rate of rise of off-state voltage of 1000 V/µs. The component operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Planar glassivated chip construction for enhanced long-term stability of blocking currents and voltages
- International standard JEDEC TO-64 package design facilitating simple mounting and space savings
- Optimized for line frequency operations in motor control and power conversion systems
Applications
- Motor control circuits
- Power converter systems
- AC power controllers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical tolerances and packaging specifications. Ensure that the procurement channel provides valid traceability for the IXYS brand component. Cross-reference the datasheet revision date to confirm compliance with current IEC 60747 standards before finalizing acquisition.
Selection Notes
Select this component based on the required voltage rating of 1200 V and the RMS current capacity of 25 A. Evaluate the thermal management requirements by considering the junction-to-heatsink thermal resistance values provided in the datasheet. Confirm that the gate trigger parameters align with the driving circuit capabilities, particularly regarding the maximum gate peak reverse voltage limits.
Part Context
This part belongs to the IXYS CS8 series of phase control thyristors, which are engineered for robust performance in high-power industrial environments. The series offers various voltage ratings from 800 V to 1200 V while maintaining consistent mechanical dimensions through the standardized TO-64 package format.
Replacement Considerations
Consult official cross-reference lists for equivalent phase control thyristors with matching 1200 V and 25 A ratings. Verify pinout compatibility and thermal resistance characteristics when evaluating alternative manufacturers.
