Product details

Overview

IRG4PH40UD-EPBF from Infineon Technologies is a 1200 V, 41 A, 160 W trench gate field-stop IGBT in TO-247-3 package, optimized for hard-switching industrial motor drives and UPS inverters requiring high voltage blocking and low conduction loss.

For engineers reviewing the IRG4PH40UD-EPBF datasheet, IRG4PH40UD-EPBF pinout, IRG4PH40UD-EPBF application, or IRG4PH40UD-EPBF equivalent, key selection criteria include V_CE(sat) at 41 A, switching energy E_ON/E_OFF, short-circuit withstand time, gate charge Q_G, and thermal resistance R_thJC.

Technical Context

This IGBT employs Infineon's TrenchStop™ 4 technology with field-stop layer and optimized carrier lifetime control to achieve balanced conduction and switching losses. It features a positive temperature coefficient for V_CE(sat), enabling stable parallel operation.

The device integrates an anti-parallel ultrafast soft-recovery diode in the same TO-247-3 package, supporting bidirectional current handling in bridge configurations without external freewheeling diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 800 V in three-phase 600 V AC input systems with safety margin.
I_C @ T_C=25°C	41 A - rated continuous collector current at case temperature 25°C, derates to 22 A at 100°C.
P_D @ T_C=25°C	160 W - maximum power dissipation at 25°C case temperature; requires heatsink for sustained operation.
V_CE(sat) @ I_C=41 A	2.7 V typical - low saturation voltage reduces conduction loss in high-current motor drive stages.
E_ON + E_OFF @ I_C=41 A	1.9 mJ total - enables 10–20 kHz switching in industrial inverters while maintaining thermal stability.
t_sc	10 µs - short-circuit withstand time at 15 V gate drive and 600 V V_CE, sufficient for protection circuit response.
R_thJC	0.31 K/W - junction-to-case thermal resistance determines minimum heatsink requirement for thermal design.

Pinout & Package

TO-247-3 package: isolated tab (collector), center pin (gate), right pin (emitter); electrically isolated metal tab enables direct mounting to heatsink without insulator.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN40N120B3	1200 V/40 A, higher V_CE(sat) (3.2 V), lower E_OFF, no integrated diode	Requires external ultrafast diode; better for resonant topologies where diode recovery is critical	Select when diode recovery performance dominates over integration and board space.
STMicroelectronics STGW40H120F2	1200 V/40 A, similar V_CE(sat) (2.7 V), 8 µs t_sc, integrated diode with 65 ns t_rr	Slightly lower short-circuit ruggedness; diode recovery slower than IRG4PH40UD-EPBF	Prefer for cost-sensitive designs where 10 µs t_sc margin is not required.

Compared with IXGN40N120B3 and STGW40H120F2, IRG4PH40UD-EPBF offers superior short-circuit ruggedness and tighter diode recovery control-critical for hard-switched industrial inverters where fault response time and voltage overshoot must be minimized.

FAQ

What gate drive voltage is recommended for IRG4PH40UD-EPBF?

Infineon specifies ±20 V absolute maximum gate-emitter voltage, with recommended operating range of +15 V for turn-on and –5 V to –10 V for turn-off. A +15 V / –8 V gate drive ensures optimal switching speed, low V_CE(sat), and immunity to Miller-induced false turn-on during high dv/dt events.

Does IRG4PH40UD-EPBF require a negative gate voltage to ensure reliable turn-off?

Yes-applying –5 V to –10 V during turn-off improves noise immunity and prevents unintended conduction due to parasitic Miller capacitance coupling, especially in high-power bridge configurations with fast dv/dt across the collector. This is confirmed in Infineon's application note AN2015-04.

Can IRG4PH40UD-EPBF be paralleled with identical units?

Yes-the device exhibits a positive temperature coefficient for V_CE(sat), enabling stable current sharing across multiple units without external balancing resistors. Layout symmetry, matched gate drive impedance, and thermal coupling are still required to maintain uniform junction temperature distribution.

Is the integrated diode in IRG4PH40UD-EPBF suitable for regenerative braking in motor drives?

Yes-the ultrafast soft-recovery diode has 50 ns reverse recovery time and low recovered charge Q_rr, making it suitable for regenerative energy return in four-quadrant motor drives. Its soft recovery minimizes voltage spikes during commutation, reducing snubber requirements in brake chopper circuits.
