Product details

Overview

IKW75N65EH5XKSA1 from Infineon is a 650 V, 75 A high-speed TRENCHSTOP™ 5 IGBT with integrated full-rated RAPID 1 antiparallel diode in PG-TO247-3 package, designed for hard-switching and resonant topologies in solar inverters, UPS systems, and welding equipment. It delivers 1.65 V V_CE(sat) at 25°C, 175°C max junction temperature, and 160 nC total gate charge.

For engineers reviewing the IKW75N65EH5XKSA1 datasheet, IKW75N65EH5XKSA1 pinout, IKW75N65EH5XKSA1 application, or IKW75N65EH5XKSA1 equivalent, key selection criteria include switching energy (E_on/E_off), diode reverse recovery performance (Q_rr = 1.33 µC, t_rr = 92 ns), thermal resistance (R_th(j–C) = 0.38 K/W), and JEDEC-qualified reliability for industrial power conversion.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop technology optimized for high-frequency operation up to 50 kHz in DC–AC and DC–DC converters. Its low Q_G (160 nC) and fast switching (t_d(off) = 174 ns, t_f = 41 ns at 75 A) reduce drive loss and enable efficient gate driver sizing.

The co-packaged RAPID 1 diode features soft recovery (I_rrm = 20.5 A, dI_rr/dt = –600 A/µs), minimizing voltage overshoot and EMI in bidirectional current paths. Thermal design is supported by separate IGBT and diode junction-to-case thermal resistances (0.38 K/W and 0.45 K/W).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE Rating	650 V - supports 400 V DC bus designs with 1.6× safety margin for transient overvoltage
I_C Continuous	75 A at T_C = 100°C - defines maximum steady-state output current under heatsink-limited conditions
V_CE(sat)	1.65 V at T_vj = 25°C - directly determines conduction loss (P_cond ≈ I_C × V_CE(sat)) in hard-switched applications
Q_G	160 nC - sets minimum gate driver peak current requirement (e.g., >20 A for 8 Ω gate resistor)
E_off	0.90 mJ at 75 A - quantifies turn-off switching loss critical for efficiency optimization in high-frequency PWM
t_rr (Diode)	92 ns at 75 A - enables clean commutation with low di/dt-induced voltage spikes in inductive loads
R_th(j–C)	0.38 K/W - allows direct thermal interface to heatsink without derating for junction-to-case path

Pinout & Package

IKW75N65EH5XKSA1 uses the PG-TO247-3 through-hole package with isolated collector tab (backside). The case serves as the collector terminal, enabling low-inductance mounting and direct thermal coupling to heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control input requiring low-impedance drive; sensitive to ESD and ringing due to 4200 pF C_ies
Pin 2 + Backside	Collector	Main high-side power terminal; backside metal provides low-inductance, high-current path and thermal conduction
Pin 3	Emitter	Power return and reference node for gate drive; internal emitter inductance is 13 nH (measured 5 mm from case)

Key Features

Feature	Design Value
High-speed TRENCHSTOP™ 5 IGBT die	Enables 50 kHz+ operation with <1.2 mJ total switching energy at 37.5 A, reducing filter size and cost
Co-packaged RAPID 1 antiparallel diode	Delivers soft, low-Q_rr (1.33 µC) recovery-critical for low EMI in solar MPPT and UPS bypass circuits
175°C maximum junction temperature	Supports compact thermal design with 35 K higher operating margin than 150°C-rated predecessors
JEDEC-qualified reliability	Validated for industrial lifetime requirements in continuous-duty converters (e.g., 20-year UPS deployments)
Pb-free, RoHS-compliant plating	Meets global environmental compliance without sacrificing solder joint integrity or thermal cycling robustness

Applications

Solar String Inverters

Uninterruptible Power Supplies (UPS)

Use Scenario: DC–AC inversion stage converting PV array output to grid-synchronized AC using three-phase NPC or T-type topologies.

IC Role / Device Role / Timing Role: Main switching device in high-side leg; handles 75 A RMS current at 16–20 kHz switching frequency with synchronous diode commutation.

Use Value: Low V_CE(sat) and soft diode recovery reduce system-level conduction and switching losses, improving inverter efficiency to >98.5% at rated load.

Use Scenario: Online double-conversion UPS where IGBTs manage battery charging, inverter output, and static bypass switching.

IC Role / Device Role / Timing Role: Bidirectional switch in inverter bridge; conducts forward current during normal mode and reverse recovery during transfer to bypass.

Use Value: 175°C rating and JEDEC qualification ensure stable operation across 0–40°C ambient with no derating, supporting N+1 redundant architectures.

Industrial Welding Converters

Mid-Frequency Induction Heaters

Use Scenario: Inverter stage of IGBT-based arc welding machines delivering 100–500 A DC output with dynamic current control.

IC Role / Device Role / Timing Role: Primary power switch modulating 400 V DC bus at 20–30 kHz; withstands repetitive short-circuit events during arc ignition.

Use Value: Turn-off SOA (300 A at 650 V, 1 µs) and low tail current minimize risk of destructive failure during load transients.

Use Scenario: Resonant half-bridge inductor-heater driving 50–200 kHz tank circuits for localized metal heating in manufacturing.

IC Role / Device Role / Timing Role: High-frequency switching element in zero-voltage switching (ZVS) topology; relies on diode reverse recovery characteristics for soft turn-on.

Use Value: Fast, soft RAPID 1 diode (t_rr = 92 ns, Q_rr = 1.33 µC) ensures reliable ZVS across full load range, reducing MOSFET replacement cost and complexity.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65H5	Lower current rating (40 A), same 650 V, 1.65 V V_CE(sat), identical RAPID 1 diode	Targeted at sub-3 kW solar microinverters and smaller UPS units	Select when thermal budget or cost constraints require lower conduction loss trade-off vs. 75 A capability
FGH75T65SHD	Same 75 A/650 V rating but uses Field Stop IV technology; higher V_CE(sat) (1.8 V), slower switching (E_off = 1.4 mJ)	Better suited for 8–15 kHz industrial motor drives where switching loss is secondary to ruggedness	Prefer for legacy designs requiring drop-in compatibility with older FS-IV platforms and higher short-circuit withstand time

Compared with IKW40N65H5 and FGH75T65SHD, IKW75N65EH5XKSA1 uniquely balances high current density, ultra-low switching energy, and soft diode recovery-making it optimal for next-generation solar and UPS systems demanding >98% efficiency at 20+ kHz.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off?

The datasheet specifies RG(off) = 8 Ω for standard test conditions (V_GE = 0/15 V, I_C = 75 A). Using >12 Ω increases t_d(off) and E_off significantly-up to 1.0 mJ at 150°C-risking thermal runaway in high-frequency operation. For robust short-circuit protection, keep RG(off) ≤ 10 Ω with active Miller clamping.

Can IKW75N65EH5XKSA1 replace IKW75N65ES5 in existing designs?

Yes-IKW75N65EH5XKSA1 is a direct plug-and-play upgrade to IKW75N65ES5, offering identical pinout, voltage rating, and package. It improves V_CE(sat) by 0.1 V and reduces E_off by 33%, enabling higher efficiency without layout or driver changes.

Is the backside collector electrically isolated from the mounting screw?

No-the backside collector is metallurgically bonded to the TO-247 case and forms part of the main current path. Mounting must use electrically insulating thermal pads or ceramic washers when the heatsink is grounded, per Infineon's Application Note AN2015-04.

Does the RAPID 1 diode support bidirectional current in synchronous rectification?

Yes-the co-packaged RAPID 1 diode is rated for 75 A continuous forward current and 300 A pulsed current, with soft reverse recovery (dI_rr/dt = –600 A/µs). It is qualified for synchronous rectification in LLC resonant converters where controlled body-diode conduction is required.
