CS29-12IO1C

Overview

The IXYS CS29-12IO1C is a phase control thyristor (SCR) housed in an ISOPLUS220 package with an electrically isolated back surface. It features a silicon chip on a Direct-Copper-Bond substrate for high power dissipation and provides 2500 V electrical isolation between the cathode and tab. The device supports a maximum repetitive peak reverse voltage of 1200 V and an RMS on-state current of 35 A. Key electrical parameters include a maximum gate trigger current of 65 mA at 25°C, a holding current of 50 mA, and a junction temperature range from -40°C to +150°C.

Feature Summary

• Electrically isolated mounting surface via Direct-Copper-Bond substrate
• High power dissipation capability with low cathode-to-tab capacitance
• Planar passivated chips ensuring long-term stability of leakage current and blocking voltage

Applications

• Motor control systems
• Power converters
• AC power controllers
• Inrush current limiting in power supplies or AC drives

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches ISOPLUS220 dimensions and pinout configuration. Ensure thermal interface materials are compatible with the isolated back surface design. Review lot traceability documentation to guarantee compliance with RoHS standards. Validate that ordering suffixes correspond exactly to the required voltage rating variant.

Selection Notes

Select this component when electrical isolation between the heat sink and circuit ground is required. The ISOPLUS220 package simplifies mounting compared to traditional insulated washers. Evaluate thermal resistance values relative to the specific heatsink design to maintain junction temperatures within limits. Consider the 2500 V isolation rating for safety-critical applications requiring galvanic separation.

Part Context

This part belongs to the IXYS CS29 series of phase control thyristors designed for high-reliability industrial applications. The series utilizes planar passivation technology to enhance performance consistency. The CS29-12IO1C specifically denotes the 1200 V blocking voltage variant within the ISOPLUS220 form factor family.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement devices match the ISOPLUS220 footprint and 2500 V isolation requirements. Verify that alternative SCR parameters meet or exceed the original 35 A RMS current and 1200 V voltage ratings.
