Infineon Technologies DDB6U104N16RRBOSA1

Overview

DDB6U104N16RRBOSA1 from Infineon Technologies is a dual-function power module integrating a 1200 V / 50 A chopper IGBT and a 1600 V / 60 A rectifier diode in a single N2 packaging platform, with integrated NTC temperature sensor (R25 = 5 kΩ) and 2.5 kV AC insulation rating; used in industrial motor drives for DC link chopper and freewheeling functions.

For engineers reviewing the DDB6U104N16RRBOSA1 datasheet, DDB6U104N16RRBOSA1 pinout, DDB6U104N16RRBOSA1 application, or DDB6U104N16RRBOSA1 equivalent, key selection criteria include its dual-device thermal coupling, 150 °C max junction temperature, low RthJC (0.38 °C/W for IGBT), and fast recovery diode Qr of 2.3 µAs at 25 °C - critical for high-efficiency regenerative braking and snubberless inverter designs.

Technical Context

This module implements a half-bridge chopper topology where the IGBT switches the DC link to control energy flow during regeneration, while the anti-parallel rectifier diode handles freewheeling current. Its integrated NTC enables real-time thermal monitoring of both semiconductor dies via shared baseplate.

The rectifier diode features soft-recovery characteristics (Qr = 2.3–6.0 µAs across 25–125 °C) and low forward slope resistance (rT = 5.5 mΩ), minimizing conduction loss during high-current freewheeling. The IGBT exhibits vCE(sat) = 2.1–2.8 V at 50 A/15 V gate drive, optimized for 1200 V bus applications with tight thermal constraints.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is 100 °C for 105 A output current under DC conditions, as defined by the Id vs. TC derating curve on page 7 of the datasheet. Operation above this temperature requires derating or forced cooling to maintain Tvj ≤ 150 °C.

Does this module support gate driving with standard ±15 V IGBT drivers?

Yes - the module accepts gate-emitter voltage within ±20 V, fully compatible with industry-standard ±15 V isolated gate drivers. Gate threshold voltage is 4.5–6.5 V, and input capacitance is 3.3 nF, enabling reliable switching with typical 2–5 A peak gate drivers.

How is the NTC thermistor electrically isolated from the power terminals?

The NTC is mounted directly on the insulated Al₂O₃ baseplate and shares no electrical connection with P/N/C/G/E terminals. Its two leads (NTC1/NTC2) are routed separately through the module housing, maintaining 2.5 kV isolation from all high-voltage nodes per IEC 61800-5-1.

Can the rectifier diode and IGBT be used independently in separate circuits?

No - the diode cathode (N) and IGBT emitter (E) are internally bonded to the same terminal. This common-emitter configuration prevents independent use; both devices must operate in coordinated chopper/freewheeling pairs within the same DC link branch.
