T390N12TOFXPSA1

Overview

The Infineon T390N12TOFXPSA1 is a Phase Controlled Thyristor (PCT) designed for high-power industrial applications. It features a repetitive peak reverse voltage of 1200 V and an average on-state current rating of 450 A. The device supports a surge current capacity of 6.8 kA and utilizes a bolted mounting configuration within the BG-T4214K0 package. Key electrical parameters include a maximum gate trigger current of 150 mA, a holding current of 200 mA, and an operating temperature range from -40°C to 125°C.

Feature Summary

• High surge current capability for robust fault handling
• Bolted terminal design for secure mechanical attachment
• Phase controlled thyristor structure for precise power regulation

Applications

• Industrial motor drives
• Resistive heating control systems
• Power supply rectification

Procurement Notes

Verify the specific suffix against official Infineon documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with existing thermal management solutions given the high current ratings. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a 1200 V blocking voltage and 450 A continuous current are required. Compare against the T390N16 series if higher voltage ratings are needed. Verify that the gate drive circuit can supply at least 150 mA to ensure reliable triggering under all operating conditions.

Part Context

This part belongs to the T390N family of phase controlled thyristors from Infineon Technologies. These devices are engineered for heavy-duty industrial environments requiring high reliability and efficient power conversion capabilities in medium to large-scale electrical systems.

Replacement Considerations

Check for direct equivalents such as the T390N12TOF variant. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement meets the same 1200 V and 450 A specifications.
