T3710N04TOFVTXPSA1

Overview

The T3710N04TOFVTXPSA1 is a silicon phase-controlled thyristor module manufactured by Infineon Technologies. It features a ceramic-sealed disc package with a diameter of 100 mm and a height of 26 mm. The device supports a maximum repetitive peak reverse voltage (VRRM) and maximum blocking voltage (VDRM) of 400 V. It provides an average on-state current (ITAVM) of 3710 A at 180 degrees electrical conduction. The surge on-state current (ITSM) capability reaches 60,000 A for a 10 ms duration at maximum junction temperature. Key thermal parameters include a maximum junction temperature of 140 °C and a thermal resistance from junction to case (RthJC) of 12.5 K/kW.

Feature Summary

• Robust ceramic-sealed disc packaging designed to prevent mechanical damage and resist adverse environmental conditions such as high humidity.
• High surge current handling capacity suitable for demanding industrial power control applications requiring significant fault tolerance.

Applications

• Industrial phase-controlled rectifiers
• DC motor drives
• Resistive load control systems

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct configuration. Confirm that the component meets all required electrical ratings for the intended circuit design before procurement. Check for any specific assembly instructions related to clamp types for bipolar power semiconductors to ensure proper installation and mechanical integrity.

Selection Notes

Select this component based on its 400 V voltage rating and 3710 A current capacity. Ensure the cooling system can maintain the junction temperature below 140 °C given the RthJC of 12.5 K/kW. Verify that the application requires a phase-controlled thyristor topology rather than other switching devices. Consider the physical dimensions of the 100 mm disc package for mechanical integration.

Part Context

This part belongs to Infineon's high-power thyristor disc series, which utilizes silicon technology for robust performance in heavy-duty applications. The T3710N04TOFVTXPSA1 variant specifically denotes the 400 V version within the T3710 family, sharing similar current capabilities with its higher voltage counterparts like the T3710N06TOF VT.

Replacement Considerations

The T3710N06TOF VT is a verified substitute offering identical current ratings but with a higher 600 V blocking voltage. Ensure the replacement fits the existing mechanical constraints and that the increased voltage rating does not conflict with system insulation requirements.
