DDB6U134N16RRBOSA1

Overview

The DDB6U134N16RRBOSA1 is a diode module with an integrated chopper IGBT in the EconoBRIDGE™ package. It features a three-phase rectifier rated for 1600 V repetitive peak reverse voltage and 134 A output current at 100°C case temperature. The unit includes a 1200 V collector-emitter chopper IGBT capable of 70 A DC collector current. An internal fast diode provides 1200 V blocking capability with 35 A continuous forward current. Thermal management relies on a maximum junction temperature of 150°C, supported by a 5 kΩ NTC thermistor connected to the baseplate for precise temperature monitoring.

Feature Summary

• Integrated brake chopper functionality combining a three-phase rectifier with a dedicated IGBT switch
• Built-in NTC thermistor for accurate thermal monitoring and protection
• High-voltage isolation with 2.5 kV insulation test voltage between terminals and baseplate
• Robust mechanical design utilizing Al2O3 internal insulation and screw-mount installation

Applications

• Industrial motor drives requiring regenerative braking capabilities
• Medium-power AC/DC conversion systems
• Pulse width modulation (PWM) converter topologies

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm that the ordering suffix BOSA1 corresponds to the specific packaging and tape-and-reel configuration required for your assembly line. Cross-reference the datasheet revision date against your bill of materials to ensure compatibility with existing design specifications.

Selection Notes

Select this module when designing circuits that require both high-current rectification and active braking control within a single footprint. Ensure the cooling system can maintain the case temperature below 100°C to support the full 134 A output rating. Verify that the gate drive circuitry accommodates the specified 15 V saturation voltage and ±20 V peak gate-emitter limits.

Part Context

This component belongs to the DDB6U series of diode modules with chopper IGBTs from Infineon Technologies. It utilizes the EconoBRIDGE™ form factor, which integrates multiple power semiconductors into a compact, standardized housing. This series is engineered for industrial applications demanding high reliability and efficient thermal dissipation in medium-power electronic converters.

Replacement Considerations

Direct replacements must match the 1600 V rectifier rating, 1200 V chopper IGBT rating, and identical EconoBRIDGE™ mounting dimensions. Verify that any substitute part maintains the same 5 kΩ NTC resistance value and pinout configuration to ensure seamless integration without PCB redesign.
