Product details

Overview

IKFW75N60ETXKSA1 from Infineon is a 600 V, 75 A TRENCHSTOP™ IGBT with integrated rapid soft-recovery anti-parallel diode in a fully isolated TO-247 package. It delivers 1.5 V V_CE(sat) at 25°C, 5 µs short-circuit withstand time at 175°C junction temperature, and 2500 V_RMS isolation for industrial motor drives and solar string inverters.

For engineers reviewing the IKFW75N60ETXKSA1 datasheet, IKFW75N60ETXKSA1 pinout, IKFW75N60ETXKSA1 application, or IKFW75N60ETXKSA1 equivalent, key selection criteria include isolated mounting surface compliance, thermal resistance (R_th(j-h) = 0.71–0.84 K/W), and diode Q_rr = 1.94 µC at 25°C for low EMI switching in high-reliability power stages.

Technical Context

This IGBT uses TRENCHSTOP™ trench-gate field-stop technology to achieve low conduction loss and positive V_CE(sat) temperature coefficient-enabling inherent current sharing in parallel configurations. Its copackaged Rapid 1 diode exhibits soft reverse recovery (trr = 107 ns, dirr/dt = −1687 A/µs) and low Q_rr, minimizing voltage overshoot and snubber stress.

The PG-TO247-3-AI package integrates a reinforced polyimide-based insulator film (152 µm, 1.3 W/mK), enabling direct heatsink mounting without additional insulation. Electrical isolation (2500 V_RMS, 50/60 Hz, 1 min) and 100% tested isolated mounting surface support safety-critical industrial UPS and welding equipment designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - Maximum blocking voltage for 400 V DC-link applications with 50% margin
I_C	75 A - Continuous collector current rating at T_h = 25°C, derated to 72 A at 65°C
V_CE(sat)	1.5 V @ 75 A, 25°C - Low conduction loss enabling <1.2% efficiency penalty in 10 kW inverters
t_SC	5 µs @ V_GE = 15 V, T_vj = 150°C - Short-circuit ruggedness supports fault-clearing in servo drive protection schemes
Q_G	440 nC - Gate charge value defining driver strength requirement (e.g., 2 A peak gate driver minimum)
R_th(j-h)	0.71–0.84 K/W - Thermal resistance from junction to heatsink, enabling 130 W dissipation at 65°C heatsink temp
trr / Q_rr	107 ns / 1.94 µC @ 25°C - Fast, soft diode recovery reduces EMI and commutation losses in bidirectional energy transfer

Pinout & Package

PG-TO247-3-AI package features a fully isolated mounting surface with internal insulator film and three terminals: Collector (C), Gate (G), and Emitter (E). The case is electrically isolated from all terminals, rated for 2500 V_RMS.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Connects to DC-link positive; carries full load current and withstands 600 V blocking
Gate (G)	Control input	Receives 15 V logic-level drive; requires 440 nC charge for full turn-on; ±20 V absolute max rating
Emitter (E)	Power return and reference node	Serves as common source for IGBT and diode; referenced to isolated heatsink; carries bidirectional current

Key Features

Feature	Design Value
TRENCHSTOP™ trench-gate structure	Enables 1.5 V V_CE(sat) and positive temperature coefficient for stable paralleling without external current-sharing resistors
Rapid 1 antiparallel diode	Soft reverse recovery (trr = 107 ns, Irrm = 23 A) minimizes voltage spikes and reduces snubber component count
Fully isolated TO-247 package	2500 V_RMS isolation and 100% tested insulated mounting surface eliminate need for mica washers or silicone pads
175°C maximum junction temperature	Supports high-power density designs with reduced heatsink size and enables operation in harsh ambient environments
Pb-free RoHS-compliant plating	Meets industrial environmental compliance requirements without compromising solder joint reliability or wire bond integrity

Applications

Industrial Motor Drives

Solar String Inverters

Use Scenario: Three-phase inverter stage in general-purpose AC drives operating at 400 V DC-link and 4 kHz switching frequency.

IC Role / Device Role / Timing Role: Main switching device in 2-level inverter leg; handles bidirectional current via integrated diode during freewheeling.

Use Value: 5 µs short-circuit withstand time enables robust overcurrent protection; low V_CE(sat) reduces conduction loss by >15% vs. legacy 600 V IGBTs.

Use Scenario: DC-AC conversion stage in single-phase transformerless solar inverters with MPPT input up to 600 V.

IC Role / Device Role / Timing Role: High-side switch in H-bridge topology; diode conducts reverse current during reactive power flow and grid synchronization.

Use Value: Soft diode recovery (Q_rr = 1.94 µC) suppresses EMI emissions below CISPR-11 Class B limits without added filtering.

Industrial UPS Systems

Resistance Welding Controls

Use Scenario: Online double-conversion UPS output inverter delivering clean 50/60 Hz sine wave under variable load (0–100%).

IC Role / Device Role / Timing Role: Output stage switch with fast dynamic response; handles overload transients and zero-crossing commutation.

Use Value: Isolated mounting surface eliminates ground-loop risks in redundant parallel UPS modules; 175°C T_vjmax supports derated operation during battery backup mode.

Use Scenario: Primary-side switching in mid-frequency (1–4 kHz) inverter-based spot welders with precise current control.

IC Role / Device Role / Timing Role: High-current pulsed switch (I_Cpuls = 225 A) controlling energy delivery to secondary winding.

Use Value: 225 A pulsed current rating and low internal emitter inductance (L_E = 13 nH) ensure sub-millisecond current rise time (<50 µs) for consistent weld nugget formation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN75N60B3	Non-isolated TO-247 package; higher V_CE(sat) (1.7 V); no integrated diode	Requires external fast diode and insulation hardware; less suitable for space-constrained UPS designs	Select when cost sensitivity outweighs isolation and integration benefits; verify external diode Q_rr matching
STMicroelectronics STGW75H65DFB	650 V rating; lower V_CE(sat) (1.45 V); non-isolated; integrated diode with slower trr (140 ns)	Higher voltage margin but increased EMI risk due to harder diode recovery; needs larger snubbers in welding apps	Prefer for 650 V systems where voltage headroom is critical; avoid in high-di/dt welding if EMI is constrained

Compared with IXGN75N60B3 and STGW75H65DFB, IKFW75N60ETXKSA1 uniquely combines full isolation, integrated soft diode, and 5 µs short-circuit capability-making it optimal for compact, safety-certified industrial inverters where board space, thermal management, and functional safety are co-constrained.

FAQ

What is the maximum allowable gate-emitter voltage for continuous operation?

The IKFW75N60ETXKSA1 has a continuous gate-emitter voltage rating of ±20 V. Transient excursions up to ±30 V are permitted for ≤10 µs with duty cycle < 0.01. Exceeding ±20 V continuously risks oxide degradation and threshold voltage shift, especially above 150°C junction temperature.

Can this IGBT be used in parallel configurations?

Yes-its positive temperature coefficient of V_CE(sat) ensures natural current balancing between paralleled units. Successful parallel operation requires matched gate drive impedance (≤5 Ω), symmetrical PCB layout, and identical heatsink contact pressure to maintain thermal uniformity across devices.

Is the isolated mounting surface rated for repeated assembly/disassembly?

The isolated surface is qualified for up to three mounting cycles using M3 screws at 0.6 Nm torque. Repeated disassembly beyond three cycles may compromise insulator film integrity or cause microcracks in the polyimide layer, reducing long-term isolation reliability.

Does the integrated diode support reverse conduction during regenerative braking?

Yes-the Rapid 1 diode is rated for 75 A continuous forward current and 225 A pulsed current, with soft recovery characteristics optimized for bidirectional energy flow. Its 1.45 V forward voltage at 75 A and 25°C enables efficient regenerative energy return in servo drives without external diode supplementation.
