T2563N85TS12XOSA1

Overview

The T2563N85TS12XOSA1 is a high-power rectifier diode disc manufactured by Infineon Technologies. It features a maximum repetitive peak reverse voltage (VRRM) of 8500 V and a maximum average forward current rating of 2563 A. The device utilizes a ceramic baseplate with a diameter of 120 mm and a height of 26 mm, designed for clamp mounting with a specified force range of 36 to 52 kN. Key electrical characteristics include a maximum junction temperature (Tvj) of 160 °C, a maximum forward voltage drop of 2.6 V at 4.0 kA, and a surge current capability (IFSM) of 50,000 A for 10 ms. Thermal resistance from junction to case (RthJC) is rated at a maximum of 8.55 K/kW.

Feature Summary

• High-voltage blocking capability up to 8500 V for demanding power conversion applications
• Robust mechanical design with ceramic insulation and standardized disc dimensions for secure clamp mounting
• High surge current handling capacity suitable for fault conditions in industrial power systems

Applications

• High-voltage direct current (HVDC) transmission systems
• Industrial motor drives and variable frequency drives
• Power supply units for heavy machinery and traction applications

Procurement Notes

Verify the specific ordering suffix XOSA1 against official Infineon documentation to confirm exact packaging, marking, and compliance details. Ensure that the required clamping force falls within the 36 to 52 kN range during assembly to maintain thermal performance and mechanical integrity. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential obsolescence notices.

Selection Notes

Select this component when designing circuits requiring high voltage isolation and significant current carrying capacity. The 8500 V rating provides substantial safety margin for high-voltage DC applications. Consider the 160 °C maximum junction temperature limit for thermal management strategies. The ceramic baseplate offers superior electrical insulation compared to standard metal-base alternatives, making it suitable for isolated mounting configurations.

Part Context

This part belongs to Infineon's high-power thyristor and diode disc family, specifically designed for industrial and traction applications. These components are characterized by their robust construction and ability to handle extreme electrical stresses. The disc form factor allows for efficient heat dissipation through direct contact with cooling surfaces via mechanical clamping.

Replacement Considerations

Consult official Infineon substitution guides or technical support for verified equivalent parts. Ensure any replacement matches the 8500 V rating, 2563 A current capacity, and 120 mm disc dimensions. Verify compatibility with existing clamp mounting hardware and thermal interface materials.
