Product details

Overview

IKW40N65F5AXKSA1 from Infineon is a 650V, 40A high-speed TRENCHSTOP™ 5 IGBT copacked with a RAPID 1 fast/soft antiparallel diode in a PG-TO247-3 package. It delivers 1.6V V_CE(sat) at 40A and 25°C, 95nC gate charge, and 175°C maximum junction temperature. Designed for hard-switching and resonant topologies in industrial DC/DC converters and battery chargers.

For engineers reviewing the IKW40N65F5AXKSA1 datasheet, IKW40N65F5AXKSA1 pinout, IKW40N65F5AXKSA1 application, or IKW40N65F5AXKSA1 equivalent, key selection criteria include V_CE(sat) stability across temperature, diode reverse recovery performance (Q_rr = 0.25–1.06 µC), switching energy (E_ts = 0.10–0.62 mJ), and AEC-Q101 qualification for rugged power control designs.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop technology with optimized carrier lifetime control to achieve low conduction loss and fast, soft switching. Its integrated RAPID 1 diode features low Q_rr, controlled dI_rr/dt (−640 A/µs max), and soft recovery-critical for reducing EMI and voltage overshoot in high-frequency converters.

The device operates with ±20V gate-emitter voltage rating and supports gate drive with 15Ω external resistors (RG(on)/RG(off)). Thermal design is enabled by 0.60 K/W IGBT and 1.80 K/W diode junction-to-case thermal resistance, allowing high-power density layouts when mounted on heatsinks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE Rating	650V - Supports 400V DC bus systems with 1.6× voltage margin for transient clamping and reliability.
I_C (continuous)	40A at T_C = 25°C - Enables compact 2–3 kW converter stages without forced air cooling.
V_CE(sat)	1.6V @ 40A, 25°C - Reduces conduction loss to ~64W at full load, improving system efficiency.
Q_G	95 nC - Determines gate driver current requirement (~6.3 A peak for 15 ns rise time).
E_off	0.10 mJ @ 5A / 400V - Low turn-off loss enables >100 kHz operation in ZVS/ZCS topologies.
trr (diode)	31 ns @ 5A - Minimizes commutation losses and dv/dt-induced shoot-through risk.
T_vj(max)	175°C - Allows derated operation up to 150°C case temperature in sealed enclosures.

Pinout & Package

PG-TO247-3 package: isolated metal tab (collector), three leads in linear configuration. Mounting torque: 0.6 Nm (M3 screw). Not recommended for surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal requiring low-inductance gate loop; connects to driver IC output via <15Ω series resistor.
Pin 2 + Backside	Collector	Main high-side power terminal; backside metal tab provides primary thermal path to heatsink.
Pin 3	Emitter	Power return and reference for gate drive; must be routed with minimal inductance to reduce voltage spikes.

Key Features

Feature	Design Value
Integrated RAPID 1 diode	Soft reverse recovery (Q_rr = 0.25 µC @ 5A) reduces EMI and snubber stress in bidirectional switching.
TRENCHSTOP™ 5 technology	Optimized trade-off between V_CE(sat) and switching speed yields 0.10 mJ E_off at 5A - 40% lower than prior-gen F4 devices.
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and UIS testing - suitable for industrial EVSE and traction auxiliaries.
Green RoHS-compliant package	Pb-free plating and halogen-free molding compound meet IPC-J-STD-609A Class 1 requirements for eco-design compliance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES5XKSA1	Same 650V/40A rating but uses TRENCHSTOP™ 5 Enhanced Speed (ES5) variant with lower Q_G (75 nC) and higher V_CE(sat) (1.75 V).	Better suited for >150 kHz ZVS designs where gate drive loss dominates; less optimal for hard-switched PFC.	Select when prioritizing gate drive efficiency over conduction loss in high-frequency resonant converters.
IGW40N65F5FKSA1	Identical die but in PG-TO247-4L package with Kelvin emitter; adds separate low-inductance emitter sense pin.	Enables precise gate control under high di/dt; required for >200 kHz operation or critical shoot-through avoidance.	Choose when designing for >150 kHz hard-switched topologies with tight timing margins or digital gate drivers.

Compared with IKW40N65ES5XKSA1, this part trades 0.15 V higher V_CE(sat) for 20 nC lower Q_G; versus IGW40N65F5FKSA1, it lacks Kelvin emitter but offers lower cost and simpler layout for standard 100–120 kHz industrial converters.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

For hard-switching at 100 kHz with 40A load, RG = 15 Ω (both turn-on and turn-off) is validated per datasheet test conditions. Using >22 Ω increases td(off) beyond 225 ns at 150°C, risking cross-conduction in bridge configurations. Lower values down to 5 Ω are acceptable if gate driver peak current rating ≥10 A and layout inductance <20 nH.

Does the integrated diode support bidirectional current in synchronous rectification?

No - the RAPID 1 diode is antiparallel and unidirectional; it conducts only from emitter to collector. It cannot replace a synchronous MOSFET in low-loss rectification. Its role is freewheeling and reverse recovery during IGBT turn-off, not active rectification.

Is thermal pad soldering required for the backside collector tab?

Yes - the metal backside is electrically and thermally connected to the collector. It must be soldered or thermally interfaced to a grounded heatsink using conductive thermal paste or phase-change pad. Insulating pads void thermal specs and risk exceeding R_th(j-c) = 0.60 K/W.

How does Q_rr variation with temperature affect snubber design?

Q_rr increases from 0.25 µC at 25°C to 1.06 µC at 150°C - a 4.2× rise. Snubber RC networks designed for room-temperature recovery will be undersized at elevated temperatures, leading to voltage overshoot. Design must target worst-case Q_rr at maximum operating T_vj (175°C), not ambient.
