Product details

Overview

IGW40N65H5AXKSA1 from Infineon is a 650 V, 40 A high-speed TRENCHSTOP™ 5 IGBT optimized for hard-switching and resonant topologies in industrial power converters. It delivers 1.66 V V_CE(sat) at 40 A and 25°C, supports 175°C maximum junction temperature, and features low gate charge (92 nC) for fast switching with reduced E_on/E_off energy-enabling efficient DC/DC converters and battery chargers.

For engineers reviewing the IGW40N65H5AXKSA1 datasheet, IGW40N65H5AXKSA1 pinout, IGW40N65H5AXKSA1 application, or IGW40N65H5AXKSA1 equivalent, key selection criteria include its 650 V breakdown rating, 175°C thermal capability, PG-TO247-3 package layout, and AEC-Q101 qualification for rugged industrial deployment.

Technical Context

This IGBT employs Infineon's fifth-generation TRENCHSTOP™ 5 trench-gate field-stop structure, enabling lower conduction loss and faster turn-off than prior generations while maintaining robust short-circuit withstand time. Its dynamic characteristics-including 149 ns t_d(off), 11 ns t_f, and 0.11 mJ E_off at 20 A/400 V-are specified under standardized inductive-load test conditions with 15 Ω gate resistors and defined stray inductance/capacitance.

The device integrates a monolithic anti-parallel diode with soft recovery behavior, and its gate-emitter threshold voltage (4.0 V typ.) and transconductance (50 S) ensure stable drive margin across -40°C to +175°C operation. Thermal resistance R_th(j–c) is 0.60 K/W, supporting high-power density designs when mounted on heatsinks with low thermal interface resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	650 V - Withstands DC bus voltages up to 650 V in industrial inverters and SMPS without derating.
I_C	40 A continuous - Rated collector current at T_C = 25°C; derates to 46 A at T_C = 100°C per thermal limits.
V_CE(sat)	1.66 V @ 40 A, 25°C - Low saturation voltage reduces conduction loss and improves efficiency in high-current switching stages.
Q_G	92 nC - Enables fast, low-loss switching with moderate gate driver strength (e.g., 2–3 A peak).
t_d(off)	149 ns @ 20 A, 25°C - Short turn-off delay supports high-frequency operation (>50 kHz) in resonant converters.
T_vj(max)	175°C - Allows sustained operation in thermally constrained enclosures and enables higher overload margins.
R_th(j–c)	0.60 K/W - Enables direct thermal coupling to heatsink; requires ≤ 0.6 K/W total system thermal resistance for full 250 W dissipation.

Pinout & Package

IGW40N65H5AXKSA1 uses the PG-TO247-3 package: insulated plastic case with three leads and electrically isolated collector tab (backside). Mounting torque: 0.6 Nm (M3 screw). Not recommended for surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; accepts ±20 V DC or ±30 V transient gate drive; requires low-inductance routing to minimize ringing.
Pin 2 & backside	Collector	Main high-side power terminal; backside metal pad serves as primary collector connection and thermal path to heatsink.
Pin 3	Emiter	Power return and reference node for gate drive; must be routed with minimal inductance to avoid shoot-through risk.

Key Features

Feature	Design Value
High-speed H5 technology	Reduces total switching energy (E_ts = 0.47 mJ @ 20 A) versus prior TRENCHSTOP™ 4, enabling >100 kHz operation in ZVS/ZCS topologies.
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST-supports industrial applications requiring extended lifetime and field robustness.
Green RoHS-compliant package	Halogen-free, lead-free PG-TO247-3 housing meets global environmental compliance without performance trade-offs.
Plug-and-play replacement	Pin-compatible and electrically compatible with IGW40N65H4 and similar predecessors, simplifying legacy design upgrades.

Applications

Battery Charger

DC/DC Converter

Use Scenario: High-efficiency 3–6 kW on-board and off-board EV battery chargers operating at 50–100 kHz with phase-shifted full-bridge topology.

IC Role / Device Role / Timing Role: Primary-side high-voltage IGBT switch handling 400–800 V DC input and delivering regulated output via transformer isolation.

Use Value: 1.66 V V_CE(sat) and low E_off reduce conduction and switching losses, improving overall charger efficiency by ≥0.8% at full load.

Use Scenario: Isolated bidirectional DC/DC stage in energy storage systems (ESS), converting between 48 V LV and 800 V HV battery banks.

IC Role / Device Role / Timing Role: High-side switch in dual-active-bridge (DAB) converter, operating with precise 500 ns dead-time control and soft-switching.

Use Value: Fast t_d(off) (149 ns) and low C_res (9 pF) enable tight timing control and reduced voltage overshoot during zero-voltage switching transitions.

Industrial Motor Drive Inverter

Uninterruptible Power Supply (UPS)

Use Scenario: 7.5–15 kW variable-frequency drives for HVAC compressors and pumps, using 6-pulse or space-vector PWM modulation.

IC Role / Device Role / Timing Role: Upper-leg IGBT in three-phase inverter bridge, switching at 8–16 kHz with active gate control.

Use Value: 175°C T_vj(max) and 0.60 K/W R_th(j–c) allow compact heatsink design and sustained 150% overload capability for 60 s.

Use Scenario: Online double-conversion UPS with 10–20 kVA rating, where IGBTs manage rectification and inverter stages in parallel-redundant configuration.

IC Role / Device Role / Timing Role: Inverter-stage switch delivering clean 50/60 Hz sine-wave output with low THD under nonlinear loads.

Use Value: Soft-recovery integrated diode and low tail current minimize commutation stress and reduce snubber requirements in high-reliability backup systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IGW40N65H5	Same die and electrical specs; differs only in packaging marking (no "XKSA1" suffix) and reel/tray packaging format.	No functional difference; identical thermal, switching, and reliability behavior in all circuit implementations.	Select IGW40N65H5 for standard distribution channels; IGW40N65H5AXKSA1 indicates Infineon's branded tape-and-reel variant with traceable lot coding.
IKW40N65ES5	650 V, 40 A TRENCHSTOP™ 5 IGBT with enhanced short-circuit ruggedness (6 µs vs. 3 µs) and slightly higher V_CE(sat) (1.75 V).	Better suited for motor drives with frequent stall events; less optimal for ultra-high-frequency DC/DC where E_off is critical.	Choose IKW40N65ES5 when short-circuit immunity outweighs switching loss minimization; otherwise prefer IGW40N65H5AXKSA1 for efficiency-critical SMPS.

Compared with IGW40N65H5 (identical core performance, differing only in packaging logistics) and IKW40N65ES5 (higher ruggedness but 0.09 V higher V_CE(sat)), IGW40N65H5AXKSA1 offers the best balance of low-loss switching, thermal headroom, and industrial qualification for high-frequency power conversion.

FAQ

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

The absolute maximum continuous gate-emitter voltage is ±20 V. Transient excursions up to ±30 V are permitted for durations ≤10 µs with duty cycle <1%. Exceeding these limits risks irreversible gate oxide damage, especially at elevated junction temperatures above 125°C.

Does IGW40N65H5AXKSA1 include an integrated freewheeling diode?

Yes-it integrates a monolithic, soft-recovery anti-parallel diode within the same TO247-3 package. The diode shares the emitter terminal (Pin 3) and collector backside, enabling compact half-bridge layouts without discrete diode placement or layout mismatch.

Can this IGBT be used in surface-mount designs?

No. The PG-TO247-3 package is through-hole only. Infineon explicitly states it is "not recommended for surface mount applications" due to mechanical stress risks during reflow and insufficient thermal pad solderability for reliable SMT attachment.

How does the 175°C maximum junction temperature impact heatsink selection?

A 175°C T_vj(max) allows 30°C higher junction rise than 145°C-rated devices, permitting either smaller heatsinks (for same power) or higher power density (for same heatsink). Required R_th(c–a) must be calculated using P_tot = 125 W at T_C = 100°C and ambient constraints-not the 250 W rating at T_C = 25°C.
