CS29-08IO1C

Overview

The IXYS CS29-08IO1C is a phase control thyristor (SCR) rated for 800 V repetitive peak reverse voltage and 35 A RMS on-state current. It utilizes an ISOPLUS220 package with an electrically isolated back surface, providing 2500 V isolation between the cathode and mounting tab. The device features a silicon chip on a Direct-Copper-Bond substrate for high power dissipation and low thermal resistance. Key electrical parameters include a maximum average forward current of 23 A at 95°C case temperature, a non-repetitive surge current of up to 215 A, and a gate trigger voltage of 1.0 V at 25°C.

Feature Summary

• Electrically isolated back surface design enabling direct heatsink mounting without additional insulators
• Silicon chip mounted on a Direct-Copper-Bond substrate for enhanced thermal performance
• Planar passivated chip structure 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 that the part number suffix matches the required voltage rating, as the series includes variants with different blocking voltages. Ensure compliance with RoHS directives if applicable to the assembly process. Review the datasheet for any product change notifications regarding pinout or dimensional updates before finalizing procurement orders.

Selection Notes

Select this component based on the specific voltage requirement, noting that the '08' suffix denotes an 800 V rating while other suffixes indicate 1200 V. Evaluate thermal management requirements using the provided junction-to-case thermal resistance values. Consider the gate trigger characteristics and di/dt capabilities when designing the drive circuitry. Verify that the operating ambient temperature allows for the necessary derating of the average forward current.

Part Context

This component belongs to the IXYS CS29 series of phase control thyristors housed in the ISOPLUS220 package. The series is characterized by its electrically isolated back surface, which simplifies mounting compared to standard configurations. The CS29-08IO1C specifically represents the 800 V variant within this family, sharing common thermal and mechanical properties with higher voltage versions like the CS29-12IO1C.
