Overview
The IXYS CS35-08IO4 is a Silicon Controlled Rectifier (SCR) designed for phase control applications. It features a TO-208AC (TO-65) package with stud mounting. Key electrical parameters include a repetitive peak reverse voltage of 800 V and a maximum DC gate trigger current of 100 mA. The device supports an RMS on-state current of 120 A and an average on-state current of 69 A. Non-repetitive peak surge current is rated at 1200 A. Operating temperature ranges from -40°C to 125°C.
Feature Summary
- Utilizes planar glassivated chip technology for enhanced long-term stability and reliable blocking performance.
- Designed specifically for line frequency phase control thyristor applications.
- Complies with international standard JEDEC TO-208AC packaging for chassis or stud mounting.
Applications
- Industrial phase control systems
- High-power rectification circuits
- Motor speed control drives
Procurement Notes
Verify the specific suffix IO4 against official IXYS documentation to confirm pinout configuration and mechanical dimensions. Ensure thermal management solutions align with the TO-208AC stud mount requirements. Confirm compliance with RoHS standards if required by the end application. Cross-reference datasheet revisions to ensure parameter consistency before integration into final designs.
Selection Notes
Select this component when high current capacity and robust blocking voltage are required in a standard industrial package. The 120 A RMS rating suits heavy-duty phase control tasks. Consider the TO-208AC form factor for compatibility with existing heatsink infrastructure. Evaluate thermal resistance characteristics against system dissipation needs to maintain junction temperatures within safe operating limits during continuous operation.
Part Context
The CS35-08IO4 belongs to the IXYS CS35 series of phase control thyristors. This series is engineered for demanding power electronics environments requiring stable operation under high current loads. The component represents a standard solution for industrial AC power regulation, offering a balance of high current handling and reliable switching characteristics in a widely recognized package format.
Replacement Considerations
Direct substitutes include other IXYS CS35 series variants such as CS35-12IO4 or CS35-14IO4, which share similar mechanical footprints but differ in voltage ratings. Verify that alternative SCR models match the 120 A RMS current requirement and TO-208AC mounting style to ensure physical and electrical compatibility without redesigning the PCB or heatsink assembly.
