Product details
Overview
IRG4PSH71UD from Infineon (formerly International Rectifier) is a 1200V, 99A ultrafast IGBT with integrated HEXFRED™ antiparallel diode in Super-247 package, optimized for hard-switching up to 40kHz and resonant soft-switching up to 200kHz in industrial motor drives, UPS inverters, and induction heating systems.
For engineers reviewing the IRG4PSH71UD datasheet, IRG4PSH71UD pinout, IRG4PSH71UD application, or IRG4PSH71UD equivalent, key selection criteria include VCE(on) = 2.52V @ 70A/15V, RθJC = 0.36°C/W, Qg = 380–570nC, trr = 110–270ns, and integrated diode recovery performance under high di/dt.
Technical Context
This Generation 4 IGBT employs field-stop trench gate structure enabling tighter parameter distribution, lower conduction loss (VCE(on) typ. 2.52V), and reduced switching losses (Etot = 18.2–19.7mJ @ 70A/960V/25°C). Its integrated HEXFRED diode delivers soft reverse recovery with Qrr = 350–1300nC and di(rec)M/dt up to 230A/µs.
The device operates across -55°C to +150°C junction range, supports ±20V gate drive, and features 5.35mm creepage distance. Thermal design is enabled by low RθJC (0.36°C/W) and flat-case mounting with recommended 20N clip force.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200V - Withstands DC bus voltages up to 960V in 3-phase inverter topologies with 20% margin. |
| IC @ TC = 25°C | 99A - Enables single-device use in 15–20kW motor drive stages without paralleling. |
| VCE(on) | 2.52V @ 70A/15V - Reduces conduction loss to ~177W at full load, easing heatsink requirements. |
| Qg | 380–570nC - Determines gate driver power demand; compatible with 2–4A peak drivers (e.g., IR2110, UCC21520). |
| trr / Qrr | 110–270ns / 350–1300nC - Enables clean turn-off in ZVS circuits and minimizes diode-induced EMI in high-frequency inverters. |
| RθJC | 0.36°C/W - Allows 140W dissipation at 100°C case temperature, supporting compact thermal designs. |
| Eoff | 9.4mJ @ 70A/960V - Dominates total loss budget in hard-switched PFC and inverter legs; benefits from low-Qgc (130–200nC). |
Pinout & Package
Supplied in industry-standard Super-247 package (pin-compatible with TO-247 but rated for higher power density), featuring isolated collector tab, insulated gate terminal, and emitter lead. Creepage distance increased to 5.35mm for enhanced safety in high-voltage industrial systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current path input | Electrically connected to metal tab; requires insulated mounting and ≥20N mechanical clamping force. |
| Gate (G) | Control electrode | High-impedance MOS-controlled terminal; requires low-inductance gate loop and RC snubber for dV/dt immunity. |
| Emitter (E) | Main current path output & diode cathode | Shared emitter node for IGBT and antiparallel diode; critical reference for gate drive return path. |
Key Features
| Feature | Design Value |
|---|---|
| UltraFast switching | Enables 40kHz hard-switching operation with Etot < 20mJ - reduces filter size and improves system efficiency in servo drives. |
| Integrated HEXFRED diode | Soft recovery (trr ≤ 270ns @ 125°C) lowers EMI and eliminates need for external snubbers in resonant converters. |
| Generation 4 IGBT die | Tighter VCE(on) distribution (±5%) enables reliable paralleling without current-sharing resistors in multi-kW inverters. |
| Super-247 package | Twice TO-247 power handling in same footprint - saves PCB area and simplifies thermal layout vs. TO-264 alternatives. |
| Lead-free construction | RoHS-compliant and halogen-free per JEDEC J-STD-020; qualified for reflow soldering up to 260°C peak. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT-inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN75N120B3 | 1200V/75A, TO-247 package, Qg = 420nC, VCE(on) = 2.7V @ 75A - higher conduction loss, no integrated diode. | Requires external fast recovery diode; suitable only where discrete diode placement is acceptable. | Prefer when cost sensitivity outweighs board space constraints and thermal performance is secondary. |
| STMicroelectronics STGW40H120DF2 | 1200V/40A, TO-247 package, integrated diode, VCE(on) = 2.6V @ 40A - lower current rating, higher RθJC (0.5°C/W). | Limited to ≤10kW systems; requires larger heatsink due to higher thermal resistance. | Select only for lower-power designs where footprint compatibility with legacy TO-247 layouts is mandatory. |
Compared with IXGN75N120B3 and STGW40H120DF2, IRG4PSH71UD delivers superior power density (99A in Super-247), lowest VCE(on), and best diode integration - making it optimal for space-constrained, high-efficiency 15–25kW industrial inverters.

FAQ
What gate resistor value is recommended for IRG4PSH71UD in a 16kHz motor drive?
A 5.0Ω gate resistor is validated in the datasheet for 70A/960V switching, yielding td(on) = 46ns and tf = 220ns. For 16kHz operation, this value balances switching speed against gate oscillation risk; lower values (3.3Ω) may be used with ferrite-beaded gate traces to suppress ringing without exceeding 4A peak driver current.
Can IRG4PSH71UD replace older IRG4PHxx series devices in existing designs?
Yes - IRG4PSH71UD shares identical Super-247 footprint and pinout with IRG4PH71UD, but offers 12% lower VCE(on) and 18% lower Eoff. No layout change is needed; gate drive voltage remains compatible at 15V, though gate charge increase (380–570nC vs. 320nC) may require verifying driver peak current capability.
How does the HEXFRED diode improve EMI performance compared to standard FRDs?
The HEXFRED diode exhibits soft, non-oscillatory reverse recovery with controlled di(rec)M/dt (150–230A/µs) and low stored charge (Qrr = 350–1300nC), reducing high-frequency spectral content above 30MHz. This directly lowers conducted EMI in input filters and eliminates need for RC snubbers on diode legs in resonant converters.
What is the maximum allowable case temperature for continuous 99A operation?
Continuous 99A operation is rated only at TC = 25°C per datasheet Fig.4. At TC = 100°C, maximum continuous current drops to 50A. To sustain 99A, case temperature must remain ≤45°C - achievable with forced-air cooling (≥10CFM) and low-thermal-resistance interface materials (RθCS ≤ 0.24°C/W).
