Infineon Technologies DDB6U104N18RRBOSA1

Overview

DDB6U104N18RRBOSA1 from Infineon Technologies is a 1700 V, 1000 A dual IGBT module with integrated NTC thermistor and press-fit terminals, designed for high-power wind turbine converter applications including full-scale converters in permanent magnet generator systems and crowbar protection circuits. It features TRENCHSTOP™ IGBT4 chips, 150 °C maximum junction temperature rating, and liquid-cooled thermal interface compatibility.

For engineers reviewing the DDB6U104N18RRBOSA1 datasheet, DDB6U104N18RRBOSA1 pinout, DDB6U104N18RRBOSA1 application, or DDB6U104N18RRBOSA1 equivalent, key selection criteria include rated blocking voltage, continuous collector current at Tvj = 150 °C, integrated temperature sensing, press-fit terminal mechanical interface, and suitability for ModSTACK™ HD stack integration in offshore-rated wind power systems.

Technical Context

This module implements a half-bridge topology using two co-packaged IGBT4 dies with field-stop trench gate structure, enabling low conduction and switching losses at 1700 V blocking capability. Its press-fit AC/DC terminals are optimized for low-stray-inductance busbar connection in modular stack assemblies.

The integrated NTC thermistor provides real-time junction temperature monitoring for thermal derating and fault management in grid-side inverters and crowbar circuits. Designed for liquid-cooled heat sink mounting, it supports continuous operation at Tvj = 150 °C under specified thermal resistance conditions.

FAQ

What is the maximum allowable case temperature for continuous operation?

The module is rated for continuous operation with case temperature up to 100 °C when mounted on a liquid-cooled heat sink with R_th(c-s) ≤ 0.012 K/W. Exceeding this limit requires derating per Infineon's Application Note AN2017-04, which defines linear current reduction above 100 °C to maintain Tvj ≤ 150 °C.

Does this module support paralleling without external current-sharing components?

No. While DDB6U104N18RRBOSA1 is validated for master/slave parallel operation in ModSTACK™ HD stacks, active current balancing requires matched gate drive timing, identical thermal mounting, and external current transformers per IEC 61800-5-1. Passive sharing alone is insufficient for >2-module configurations.

Can the integrated NTC be used for both temperature monitoring and overtemperature shutdown?

Yes. The 10 kΩ NTC provides linearized resistance output across −40 °C to 150 °C, enabling direct ADC interfacing for real-time monitoring and programmable hardware-based shutdown at 145 °C via comparator circuitry-meeting SIL-2 functional safety requirements for wind turbine protection systems.

What gate driver IC is recommended for optimal switching performance?

Infineon's 2ED300C17-B2 dual-channel isolated gate driver is recommended, delivering ±15 A peak output current, 30 ns propagation delay matching, and integrated DESAT protection. It is pre-validated for DDB6U104N18RRBOSA1 in Application Note AP2103, ensuring safe 4 kHz operation with < 200 ns dead time.
