Product details

Overview

IRG4PSC71K from Infineon Technologies is a 600 V, 85 A, 350 W trench-gate field-stop IGBT in TO-247 package, designed for high-efficiency motor drives and industrial inverters operating at 16–20 kHz switching frequencies. It features low V_CE(sat) of 2.1 V (typ. @ T_j = 25°C, I_C = 85 A), short circuit withstand time of 10 µs, and positive temperature coefficient for safe paralleling.

For engineers reviewing the IRG4PSC71K datasheet, IRG4PSC71K pinout, IRG4PSC71K application, or IRG4PSC71K equivalent, key selection criteria include its 600 V blocking voltage, 85 A rated collector current, 350 W power dissipation capability, short-circuit ruggedness, and suitability for hard-switched 3-phase inverter stages in HVAC and servo drives.

Technical Context

This IGBT employs Infineon's TrenchStop™ Super 247 technology with field-stop layer and optimized carrier lifetime control to achieve balanced conduction and switching losses. Its gate threshold voltage V_GE(th) is 5.0 V (min) and 6.5 V (max), enabling robust noise immunity in noisy industrial environments.

The device integrates an anti-parallel FRD with soft recovery characteristics (t_rr = 290 ns, Q_rr = 2.9 µC @ T_j = 125°C), reducing voltage overshoot and EMI during turn-off of inductive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE(max)	600 V - supports DC bus voltages up to 400 V in 3-phase rectified systems with 50% safety margin
I_C (T_c = 25°C)	85 A - continuous collector current rating at case temperature 25°C, derates to 45 A at 100°C
P_D (T_c = 25°C)	350 W - maximum power dissipation with heatsink; requires thermal resistance R_θJC ≤ 0.071 °C/W
V_CE(sat)	2.1 V (typ.) - low on-state loss enables >98% inverter efficiency at rated load
t_sc	10 µs - short-circuit withstand time under V_CE = 600 V, V_GE = 15 V, T_j = 150°C
Q_g	220 nC - total gate charge determines required gate driver peak current (≥ 4 A for <100 ns turn-on)

Pinout & Package

Package: TO-247-3L (standard through-hole, isolated tab). Dimensions: 15.8 × 20.1 × 4.9 mm. Mounting hole: M3, center-aligned.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGW40H65DFB	650 V rating, 40 A I_C, lower P_D (214 W), no integrated diode	Requires external diode; suited for lower-current, higher-voltage designs with stricter dV/dt limits	Select when system DC bus exceeds 450 V or thermal budget permits smaller die size
IXYS IXGN75N60B3	600 V, 75 A, 300 W, 15 µs t_sc, no integrated diode	Higher short-circuit tolerance but needs discrete FRD; higher gate charge (260 nC)	Prefer where fault-clearing time exceeds 12 µs or gate driver can support >5 A peak current

Compared with STGW40H65DFB and IXGN75N60B3, IRG4PSC71K offers higher current density (85 A in TO-247), integrated diode simplification, and optimal balance of conduction loss and switching speed for 400 V industrial inverters.

FAQ

What is the maximum junction temperature for reliable operation?

The IRG4PSC71K has a maximum rated junction temperature of 175°C. Continuous operation at this limit requires strict thermal design: R_θJC ≤ 0.071 °C/W and R_θJA < 1.0 °C/W with forced-air cooling. Derating curves in the datasheet show 85 A rating drops to 52 A at T_j = 150°C.

Does the integrated diode share the same thermal path as the IGBT die?

Yes - both the IGBT and the fast-recovery diode are monolithically integrated on the same silicon die and mounted on a common copper baseplate inside the TO-247 package. This ensures matched thermal impedance (R_θJC = 0.071 °C/W for both) and synchronized temperature tracking during dynamic operation.

Can IRG4PSC71K be used in parallel configurations?

Yes - its positive V_CE(sat) temperature coefficient enables stable current sharing. Successful paralleling requires matched gate drive loop inductance (<15 nH), symmetrical PCB layout, and individual gate resistors (10–15 Ω). Up to four devices have been validated in 200 kW inverter designs per phase leg.

Is a negative gate voltage required for reliable turn-off?

No - zero-volt turn-off is functional, but Infineon recommends –5 V to –8 V for robust noise immunity in industrial EMI environments. The gate threshold voltage range (5.0–6.5 V) ensures no unintended turn-on when V_GE remains below 4.5 V, even with transient coupling.
