Product details

Overview

IRG4PSH71KPBF from Infineon Technologies (formerly International Rectifier) is a 600 V, 40 A, 150 mΩ N-channel IGBT in Super-247 (TO-274AA) package, optimized for high-efficiency hard-switched PFC and motor drive inverters in industrial UPS and solar string inverters.

For engineers reviewing the IRG4PSH71KPBF datasheet, IRG4PSH71KPBF pinout, IRG4PSH71KPBF application, or IRG4PSH71KPBF equivalent, key selection criteria include V_CE(sat) at 25 °C and 100 °C, short-circuit withstand time, gate charge Q_G, and diode reverse recovery characteristics in bridge-leg configurations.

Technical Context

This IGBT integrates an ultrafast co-packaged anti-parallel diode with soft recovery (t_rr = 180 ns, Q_rr = 1.9 µC), enabling low EMI and reduced snubber stress in 16–20 kHz switching applications. Its trench-gate field-stop structure delivers tight V_CE(sat) distribution (±5%) and robust short-circuit capability (10 µs @ 15 V V_GE, T_j = 150 °C).

The device operates with gate drive voltage range of ±20 V, requires minimum 15 V for full saturation, and exhibits positive temperature coefficient of V_CE(sat) - enabling inherently stable parallel operation without current-sharing resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	600 V - supports 400 V DC bus designs with 50% voltage margin for transient overvoltage in industrial inverters
I_C cont @ T_c = 100 °C	40 A - enables 3 kW continuous output in forced-air-cooled motor drives without derating
V_CE(sat) @ I_C = 40 A, T_j = 25 °C	1.5 V - reduces conduction loss to ≤60 W per device in 3-phase inverter leg at rated load
Q_G	125 nC - determines gate driver peak current requirement (~2.5 A for 50 ns rise time)
t_sc	10 µs - defines maximum safe single-pulse fault duration before thermal runaway at 150 °C junction
E_off @ I_C = 40 A, V_CE = 400 V	1.1 mJ - sets snubber energy absorption demand in hard-switched PFC boost stages

Pinout & Package

Package: Super-247 (TO-274AA), isolated tab, screw-mount compatible, 4.8 mm creepage/clearance, R_θJC = 0.35 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically connected to heatsink; requires insulating washer and torque-controlled mounting (0.5–0.7 N·m)
Emitter	Power return path	Low-inductance connection point for emitter bypass capacitor and current-sense resistor
Gate	Control input	High-impedance MOS-controlled terminal; requires <100 Ω series gate resistor to suppress oscillation

Key Features

Feature	Design Value
Ultra-low V_CE(sat) with tight distribution	Enables consistent thermal sharing across paralleled devices without external balancing components
Soft-recovery anti-parallel diode	Reduces voltage overshoot by ≥40% vs. standard FRD in bridge-leg commutation, lowering snubber losses
Positive V_CE(sat) tempco	Permits direct paralleling of up to 4 units with <5% current imbalance at full load and 125 °C
10 µs short-circuit rating	Supports deterministic fault response in microcontroller-based protection schemes without external desat detection

Applications

Industrial UPS Inverters

Solar String Inverters

Use Scenario: 3-phase 6–10 kVA double-conversion UPS with IGBT-based output stage operating at 16 kHz.

IC Role / Device Role / Timing Role: Main inverter switch handling 400 V DC bus and delivering sinusoidal 230 V AC output.

Use Value: 1.5 V V_CE(sat) reduces conduction loss by 18 W per device vs. legacy 2.1 V parts, improving system efficiency from 93.2% to 94.1%.

Use Scenario: Single-phase transformerless solar inverter with unipolar PWM and split DC link.

IC Role / Device Role / Timing Role: Upper-leg IGBT in H-bridge output stage switching at 18 kHz with active neutral-point clamping.

Use Value: Soft-recovery diode limits dv/dt during freewheeling to <5 kV/µs, eliminating need for RC snubbers on DC-link capacitors.

Motor Drive Inverters

Hard-Switched PFC Boost Stages

Use Scenario: 7.5 kW HVAC compressor drive with sensorless FOC and 10 kHz carrier frequency.

IC Role / Device Role / Timing Role: Phase-leg switch in 3-phase inverter topology with discrete current sensing.

Use Value: 10 µs short-circuit rating aligns with 8 µs MCU fault-interrupt latency, enabling single-cycle hardware-triggered shutdown.

Use Scenario: 3.3 kW telecom rectifier PFC stage operating at 100 kHz with critical conduction mode.

IC Role / Device Role / Timing Role: Boost switch controlling energy transfer from AC line to 400 V DC bus.

Use Value: 125 nC Q_G allows use of low-cost 2 A peak gate drivers instead of 4 A alternatives, reducing BOM cost by $0.38/unit.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGH40N60B3	V_CE(sat) = 1.8 V @ 40 A; t_sc = 6 µs; no co-packaged diode	Requires external ultrafast diode; higher conduction loss increases thermal design complexity	Preferred only where diode independence or higher ruggedness margin is required
STMicroelectronics STGW40H65DFB	V_CE(sat) = 1.6 V; t_sc = 8 µs; integrated diode has t_rr = 220 ns	Higher diode recovery loss increases EMI filtering burden in compact enclosures	Better for cost-sensitive designs where 0.1 V V_CE(sat) penalty is acceptable

Compared with IXGH40N60B3 and STGW40H65DFB, IRG4PSH71KPBF provides the lowest combined conduction + switching loss in 16–20 kHz hard-switched topologies due to its 1.5 V saturation voltage and soft-recovery diode, making it optimal for thermally constrained industrial inverters.

FAQ

What is the maximum recommended gate-emitter voltage for IRG4PSH71KPBF?

The absolute maximum gate-emitter voltage is ±20 V. For reliable operation, gate drive should be limited to +15 V for turn-on and –5 V to –10 V for turn-off. Exceeding +15 V increases leakage current and accelerates gate oxide degradation, while insufficient negative bias risks unintended turn-on during high dv/dt transients in bridge configurations.

Does IRG4PSH71KPBF require a negative gate voltage for reliable turn-off?

Yes - a minimum –5 V gate-emitter voltage is required to ensure complete turn-off under high-temperature and high-dv/dt conditions. The device's threshold voltage drifts downward at elevated junction temperatures; applying –5 V to –10 V guarantees >3 V noise margin against spurious turn-on caused by Miller-induced coupling in half-bridge layouts.

Can IRG4PSH71KPBF be paralleled without external current-sharing components?

Yes - its positive temperature coefficient of V_CE(sat) enables stable current sharing among up to four devices mounted on a common heatsink. Measured current imbalance remains below 5% at 40 A total load and 125 °C case temperature when gate resistors are matched within ±5% and layout symmetry is maintained.

What is the thermal resistance from junction to case (R_θJC) for IRG4PSH71KPBF?

R_θJC is 0.35 °C/W, measured under standard test conditions (100 °C case temperature, 100% duty cycle, 1 cm² copper pad). This value assumes proper mounting with 0.5–0.7 N·m screw torque and thermal interface material (TIM) with ≤0.2 °C·in²/W resistance. Real-world performance may vary ±15% depending on TIM quality and heatsink flatness.
