Procurement Notes

Verify the exact part number suffix against official Infineon documentation to confirm specific manufacturing lot or revision details. Confirm that the requested quantity aligns with the manufacturer's standard packaging requirements. Ensure compatibility with existing cooling systems given the high current rating. Check for any obsolescence notices as this series may have limited availability compared to newer generations.

Selection Notes

Select this component when designing circuits requiring high voltage isolation and significant continuous current capacity. Evaluate the thermal resistance parameters to ensure adequate heat sinking is implemented. Compare the gate trigger specifications with the available drive circuitry to guarantee reliable turn-on. Consider the physical dimensions of the disc package for mechanical integration within the enclosure.

Part Context

This part belongs to Infineon's high-power thyristor portfolio, specifically engineered for phase control applications. It represents a legacy series often used in established industrial infrastructure. Engineers typically select these devices for their proven reliability in high-voltage environments where silicon-controlled rectifiers are preferred over faster switching devices due to cost and ruggedness.

Replacement Considerations

Direct replacements must match the 2800 V voltage rating and 1590 A current capacity. Verify that alternative parts from other manufacturers offer compatible pinout configurations if applicable, though disc thyristors often require custom mounting solutions. Ensure the replacement maintains similar thermal characteristics and gate trigger requirements.
