Product details

Overview

AUIRGU4045D from Infineon Technologies is an automotive-qualified 600 V, 12 A trench IGBT with integrated ultrafast soft-recovery co-pack diode in D-Pak (TO-252) package. It delivers 2.07 V V_CE(on) at 6 A/15 V/25°C, 5 µs short-circuit safe operating area (SCSOA), and 175°C maximum junction temperature-enabling high-efficiency motor control in 48 V–400 V DC bus inverters for electric power steering and HVAC blowers.

For engineers reviewing the AUIRGU4045D datasheet, AUIRGU4045D pinout, AUIRGU4045D application, or AUIRGU4045D equivalent, key selection criteria include its square RBSOA, 178 µJ E_rec diode reverse recovery energy at 175°C, 13 nC typical gate charge, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This IGBT employs trench-gate field-stop technology with positive V_CE(on) temperature coefficient and tight parameter distribution-ensuring stable current sharing in parallel configurations. Its co-pack diode features soft recovery (t_rr = 74 ns, I_RR = 12 A at 175°C) and low E_rec (178 µJ), minimizing voltage overshoot and EMI during commutation.

The device supports robust transient operation via full-square RBSOA up to 600 V and 5 µs SCSOA at V_GE = 20 V. Thermal design is enabled by validated R_θJC values: 1.9 °C/W (IGBT) and 6.8 °C/W (diode), measured on FR-4 PCB with 1"² copper pad.

FAQ

What is the maximum recommended gate resistor value for reliable switching at 100 kHz?

The datasheet specifies 47 Ω as the test condition for switching loss characterization at 100 kHz. Using >100 Ω increases turn-off delay (t_d(off) = 95 ns at 175°C) and risks exceeding SCSOA limits during faults. For 100 kHz operation, 22–47 Ω is optimal-balancing E_off (189 µJ at 175°C) and dv/dt control without compromising short-circuit ruggedness.

Can AUIRGU4045D replace AUIRGR4045D in existing designs?

Yes-AUIRGU4045D and AUIRGR4045D share identical electrical specifications, thermal ratings, and pinout. The "U" suffix denotes D-Pak (TO-252) packaging, while "R" indicates I-Pak (TO-220AB); both are electrically interchangeable but require footprint revision due to different thermal pad layouts and mounting holes.

Is the co-pack diode rated for continuous reverse recovery at 175°C?

Yes-the diode's reverse recovery parameters (t_rr = 74 ns, I_RR = 12 A, E_rec = 178 µJ) are fully characterized at T_J = 175°C per Figure 17–21. Its soft recovery waveform (low I_RR/t_rr ratio) prevents oscillatory turn-off and ensures stable operation in hard-switched inverters up to the rated junction temperature.

Does the 5 µs SCSOA apply to all gate drive voltages?

No-the 5 µs SCSOA is validated only at V_GE = 20 V per Figure 22. At V_GE = 15 V, the safe time reduces to ~3.2 µs due to slower current rise and increased tail current. Designers must use V_GE ≥ 18 V and active desaturation detection to guarantee full 5 µs fault tolerance in automotive safety-critical applications.
