T1500N14TOFVTXPSA1

Overview

The T1500N14TOFVTXPSA1 is an Electrical Triggered Phase Control Thyristor manufactured by Infineon Technologies. It features a 1400 V repetitive peak reverse voltage and a maximum average on-state current of 1500 A at 85°C with a 180° electrical sine wave conduction angle. The device supports a non-repetitive surge current of 33,500 A over 10 ms at maximum junction temperature. Key thermal characteristics include a maximum junction-to-case thermal resistance of 18.4 K/kW and a maximum junction temperature of 125°C. The component utilizes a disc package with a diameter of 75 mm and height of 26 mm, sealed in ceramic.

Feature Summary

• High surge current capability for robust operation under fault conditions
• Sealed ceramic housing provides protection against mechanical damage and high humidity
• Designed for full blocking capability across wide temperature ranges at 50/60 Hz frequencies

Applications

• Phase control applications in high-power industrial systems
• Rectifier circuits for drive applications
• Energy conversion systems requiring high reliability

Procurement Notes

Verify the complete part number including the XPSA1 suffix to ensure correct configuration. Confirm that the ordering quantity aligns with the manufacturer's standard factory pack size. Check for RoHS compliance status as indicated in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 1400 V blocking voltage and 1500 A continuous current handling. Ensure the cooling solution can maintain the junction temperature below 125°C given the specified thermal resistance. Verify that the gate triggering circuitry matches the requirements for electrical triggered thyristors.

Part Context

This part belongs to the Infineon T1500N series of phase control thyristors. It shares the same physical dimensions and general topology as variants like T1500N12TOF and T1500N16TOF, differing primarily in their voltage ratings. The TOF designation indicates a specific disc package format used for high-power bipolar semiconductors.

Replacement Considerations

Direct replacements within the same family include T1500N12TOF and T1500N16TOF, provided the voltage rating differences are acceptable for the application. Cross-vendor substitutes require careful evaluation of thermal resistance and surge current capabilities.
