DD450S45T3E4BPSA1

Overview

The DD450S45T3E4BPSA1 is a silicon diode module manufactured by Infineon Technologies, designed for high-power industrial applications. It features a reverse voltage rating of 4.5 kV and a continuous forward current capacity of 450 A. The device exhibits a forward voltage drop of 2.6 V at rated conditions and supports a maximum power dissipation of 1.5 MW. It utilizes screw mount installation within the AG-XHP100-3 package configuration.

Feature Summary

• High-voltage insulation capability with 4.5 kV blocking rating
• High-current handling performance up to 450 A
• Robust thermal management supporting 1.5 MW power dissipation
• Industrial-grade reliability using silicon technology

Applications

• High-power rectifier circuits in industrial converters
• Freewheeling diodes in IGBT-based inverter systems
• DC link applications requiring high surge current tolerance
• Medium voltage drive systems

Procurement Notes

Verify the exact suffix BPSA1 against official Infineon documentation to confirm pinout and terminal configuration. Ensure compatibility with AG-XHP100-3 mounting hardware. Confirm RoHS compliance status through the latest datasheet revision. Validate thermal interface requirements for the specified power dissipation level before integration.

Selection Notes

Select this component when system design requires a standalone high-voltage diode rather than an integrated switch-diode pair. The 4.5 kV rating provides margin for transient overvoltages in medium-voltage networks. Consider the 2.6 V forward voltage impact on conduction losses during efficiency calculations. Verify that the 450 A current rating aligns with peak load demands and thermal constraints.

Part Context

This module belongs to Infineon's high-power discrete diode portfolio, specifically engineered for demanding industrial environments. It complements the company's IGBT modules by providing complementary switching elements. The XHP series packaging enables efficient heat transfer to cold plates, supporting compact converter designs in traction and renewable energy sectors.

Replacement Considerations

Cross-reference part number DD450S45T3E4_B5 for equivalent specifications. Verify mechanical footprint compatibility with existing PCB or busbar layouts. Confirm electrical parameter alignment, particularly forward voltage and recovery characteristics, to ensure circuit performance stability.
