Product details
Overview
AIKB40N65DF5ATMA1 from Infineon Technologies is an automotive-qualified 650 V, 40 A field-stop TRENCHSTOP™ 5 IGBT in TO-263-7 (D²PAK) package with integrated co-packaged fast-recovery anti-parallel diode and low VCE(sat) of 1.6 V @ Tj = 150 °C. It is designed for high-efficiency main inverter and auxiliary inverter stages in electric and hybrid vehicles, supporting motor drive and regenerative braking in 3-phase B6 bridge topologies.
For engineers reviewing the AIKB40N65DF5ATMA1 datasheet, AIKB40N65DF5ATMA1 pinout, AIKB40N65DF5ATMA1 application, or AIKB40N65DF5ATMA1 equivalent, key selection criteria include its 650 V blocking voltage, 40 A rated current, 1.6 V saturation voltage at 150 °C, integrated diode softness (trr = 290 ns), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This IGBT employs Infineon's TRENCHSTOP™ 5 silicon technology with field-stop layer and optimized trench gate structure to achieve low conduction loss without compromising switching speed. Its design targets hard-switched 3-phase inverters operating up to 20 kHz with gate charge Qg = 120 nC and turn-off energy Eoff = 1.1 mJ @ VCC = 600 V, IC = 40 A, RG = 10 Ω.
The integrated ultrafast soft-recovery diode features reverse recovery time trr = 290 ns and peak reverse recovery current IRRM = 48 A, enabling reduced voltage overshoot and EMI in bidirectional energy flow applications such as regenerative braking and auxiliary inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 650 V - supports DC-link voltages up to 500 V nominal in EV main inverters with 20 % safety margin |
| IC @ Tc = 100 °C | 40 A - continuous collector current rating enabling compact 30–50 kW auxiliary inverter designs |
| VCE(sat) @ IC = 40 A, Tj = 150 °C | 1.6 V - reduces conduction loss by ~25 % vs. prior-generation IGBTs, improving inverter efficiency at partial load |
| Eoff @ VCC = 600 V, IC = 40 A | 1.1 mJ - enables 15–20 kHz switching in thermally constrained modules without excessive heatsink requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGW40H65DFB-4 | 650 V, 40 A; higher VCE(sat) = 1.75 V @ 150 °C; slower diode trr = 380 ns | Less suitable for high-frequency regenerative braking due to higher switching loss and harder diode recovery | Prefer when cost sensitivity outweighs 0.5 % system efficiency gain and EMI constraints are relaxed |
| IXYS IXYP40N65C5 | 650 V, 40 A; no integrated diode; requires external ultrafast diode; higher Rth(j-c) = 0.75 K/W | Requires additional component count and PCB area; less optimal for space-constrained automotive modules | Consider only if discrete diode selection is mandatory for legacy design reuse or thermal interface constraints prevent D²PAK mounting |
Compared with STGW40H65DFB-4 and IXYP40N65C5, AIKB40N65DF5ATMA1 delivers lower conduction loss, softer diode recovery, and superior thermal resistance-making it the preferred choice for new automotive inverter designs targeting ASIL-B compliance and >96 % inverter efficiency.

FAQ
What is the maximum junction temperature rating for AIKB40N65DF5ATMA1?
The absolute maximum junction temperature is 175 °C, with continuous operation rated up to 150 °C per AEC-Q101 stress testing conditions. Derating curves in the datasheet specify that at Tc = 100 °C, the device supports 40 A DC current; above this case temperature, linear derating applies down to zero current at 175 °C junction.
Does AIKB40N65DF5ATMA1 require a negative gate voltage for reliable turn-off?
No, AIKB40N65DF5ATMA1 is fully specified for 0 V to +15 V gate drive with no requirement for negative bias. Its gate threshold voltage VGE(th) is 5.0 V min, and the device remains safely off with 0 V gate potential under all operating conditions, simplifying gate driver design in automotive systems.
Can the integrated diode be used independently of the IGBT in bidirectional topologies?
Yes-the diode shares the collector and emitter terminals with the IGBT but operates autonomously during reverse conduction. In synchronous rectification or regenerative braking modes, the diode conducts freewheeling current even when the IGBT is off, and its soft recovery behavior is characterized separately in the datasheet with trr = 290 ns and Qrr = 1.1 µC.
Is AIKB40N65DF5ATMA1 compliant with RoHS and REACH regulations?
Yes, AIKB40N65DF5ATMA1 is lead-free and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Infineon confirms substance declarations per IPC-1752A, with no SVHC substances above 0.1 % w/w threshold in homogeneous materials.
