Product details

Overview

IRG4PH40K from Infineon Technologies (formerly International Rectifier) is a short-circuit-rated n-channel UltraFast IGBT in TO-247AC package, rated for 1200 V V_CES, 30 A continuous collector current at T_C = 25°C, and 10 µs short-circuit withstand time at V_CC = 720 V and T_J = 125°C. It delivers 2.74 V typical V_CE(on) at 15 A/15 V_GE, enabling high-efficiency motor control inverters up to 960 V DC bus.

For engineers reviewing the IRG4PH40K datasheet, IRG4PH40K pinout, IRG4PH40K application, or IRG4PH40K equivalent, key selection criteria include short-circuit ruggedness (t_sc = 10 µs), low conduction loss (V_CE(on) ≤ 3.4 V), tight parameter distribution across temperature, gate charge (Q_g = 94–140 nC), and thermal resistance (R_θJC = 0.77 °C/W).

Technical Context

This IGBT employs a fourth-generation trench-gate field-stop structure optimized for high-voltage industrial motor drives. Its design integrates low saturation voltage with fast switching (t_r = 22 ns, t_f = 150–230 ns) and controlled tail current to minimize total switching losses (E_ts = 2.39–4.93 mJ depending on T_J and I_C).

The device features a positive temperature coefficient for V_CE(on) (0.37 V/°C) and negative threshold voltage drift (−3.3 mV/°C), supporting inherently stable parallel operation and overtemperature protection. Gate drive requirements are defined by Q_ge = 14–22 nC and Q_gc = 37–55 nC, with recommended R_G = 10 Ω for balanced E_on/E_off trade-off.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - supports 960 V DC bus designs with 25% voltage margin
I_C (T_C = 25°C)	30 A - enables compact 15–20 kW motor inverter modules without forced cooling
V_CE(on) typ.	2.74 V @ 15 A, 15 V_GE - reduces conduction loss to ~41 W at full load
t_sc	10 µs @ V_CC = 720 V, T_J = 125°C - allows robust fault handling in servo drives
Q_g	94–140 nC - determines gate driver peak current requirement (~14 A for 10 ns rise)
R_θJC	0.77 °C/W - enables 65 W dissipation at 100°C case temperature with <10°C junction rise
E_off	1.66 mJ @ 15 A, 960 V - sets minimum snubber energy and heatsink sizing for hard-switched topologies

Key Features

Feature	Design Value

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 IXGN120N120A3	1200 V, 120 A, R_θJC = 0.25 °C/W, t_sc = 10 µs, Q_g = 220 nC	Higher current rating and lower thermal resistance, but 2.3× higher gate charge increases driver complexity	Select when >60 A peak current or <5°C/W system thermal budget is required; not drop-in due to larger footprint
STMicroelectronics STGW40H120DF2	1200 V, 40 A, V_CE(on) = 2.6 V @ 20 A, t_sc = 6 µs, Q_g = 110 nC	Lower V_CE(on) but reduced short-circuit capability; integrated diode has slower recovery than HEXFRED pairing	Prefer for cost-sensitive 10–15 kW drives where fault-clearing time <6 µs is acceptable; requires revised gate drive tuning

Compared with IXGN120N120A3 and STGW40H120DF2, the IRG4PH40K offers optimal balance of ruggedness (10 µs t_sc), gate drive simplicity (94–140 nC), and thermal efficiency (0.77 °C/W) for 15–22 kW industrial inverters requiring field-proven reliability.

FAQ

What is the maximum gate-emitter voltage rating for IRG4PH40K?

The absolute maximum V_GE is ±20 V. Operation above +15 V or below −10 V risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and −5 V to −10 V for turn-off to ensure fast, noise-immune commutation and prevent spurious turn-on during high dv/dt events.

Can IRG4PH40K be paralleled without active current balancing?

Yes - its fourth-generation process provides tight V_CE(on) and Q_g distribution (±10% and ±15%, respectively), enabling stable static and dynamic current sharing among up to four devices using matched gate resistors and symmetrical PCB layout, without auxiliary emitter resistors or current-sense feedback.

What is the recommended freewheeling diode for use with IRG4PH40K?

Infineon recommends pairing with HEXFRED™ ultrafast, ultrasoft recovery diodes (e.g., IDP12E65D1). These diodes exhibit <25 ns reverse recovery time and near-zero reverse recovery charge, minimizing voltage overshoot and EMI during IGBT turn-off while reducing total system switching losses by up to 18% compared to standard fast recovery diodes.

Does IRG4PH40K require a negative gate voltage for reliable turn-off?

A negative gate voltage (−5 V to −10 V) is strongly recommended for robust turn-off in noisy industrial environments. While the device will turn off with 0 V gate drive, negative bias prevents false turn-on caused by Miller-induced dv/dt coupling during high-current switching, especially critical in 3-phase bridge configurations with >1 kV/µs collector voltage transients.
