Product details
Overview
DD400S33K2CB3NDSA1 from Infineon Technologies is a 3.3 kV, 400 A reverse-conducting diode module designed for high-power inverter legs in industrial traction and medium-voltage drives. It features 3300 V repetitive peak reverse voltage, 800 A repetitive peak forward current, 55.5 kA²s I²t rating, and operates up to 125°C junction temperature in motor drive inverters.
For engineers reviewing the DD400S33K2CB3NDSA1 datasheet, DD400S33K2CB3NDSA1 pinout, DD400S33K2CB3NDSA1 application, or DD400S33K2CB3NDSA1 equivalent, key selection criteria include its 3300 V VRRM rating, 400 A continuous DC forward current, low 51.0 K/kW junction-to-case thermal resistance per diode, and compatibility with FF400R33KF2C IGBT modules in dual-switch configurations.
Technical Context
This diode module is engineered for anti-parallel operation with 3.3 kV IGBTs in three-phase voltage-source inverters. Its dynamic recovery characteristics-235–440 µC recovered charge (Qr) and 245–515 mJ reverse recovery energy (Erec) at 400 A-are specified under standardized conditions (VR = 1800 V, -diF/dt = 2200 A/µs, VGE = -15 V).
The module uses AlN ceramic isolation on an AlSiC baseplate, delivering 6.00 K/kW case-to-heatsink thermal resistance per module and 25 nH stray inductance (LsCE). Its 6.0 kV isolation test voltage and >400 CTI support safe operation in harsh industrial environments requiring reinforced insulation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum allowable junction temperature for continuous operation?
The DD400S33K2CB3NDSA1 has a maximum junction temperature (Tvj op) of 125°C for continuous operation, validated under rated 400 A forward current and proper heatsink mounting with λgrease = 1 W/(m·K). Operation beyond this limit risks irreversible degradation of the AlN isolation layer and silicon die.
Can this diode module be used without a matching IGBT module?
Yes, it can operate standalone in rectifier or freewheeling applications, but its dynamic parameters (Qr, Erec, IRM) are characterized in conjunction with the FF400R33KF2C IGBT module. Using it with non-matched IGBTs may cause unbalanced loss distribution and premature failure due to mismatched recovery timing.
What is the significance of the 'B3NDSA1' suffix in the part number?
The 'B3NDSA1' suffix denotes a specific variant with enhanced creepage and clearance distances (32.2 mm), optimized M6 mounting hardware, and compliance with EN 50124-1 for railway applications. It also indicates inclusion of Infineon's standard thermal interface paste and mechanical alignment features for automated assembly.
How does the 25 nH stray inductance affect gate driving requirements?
The 25 nH LsCE contributes directly to voltage overshoot (V = L × di/dt) during diode reverse recovery. At 2200 A/µs diF/dt, this generates ~55 V overshoot-requiring gate drivers with sufficient negative bias (-15 V) and low-inductance layout to suppress oscillation and ensure reliable IGBT turn-off in shared-leg configurations.
