Product details

Overview

IKW40N65H5AXKSA1 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 1.66V V_CE(sat) at 40A and 25°C, supports 175°C junction operation, and targets hard-switching and resonant DC/DC converters and battery chargers.

For engineers reviewing the IKW40N65H5AXKSA1 datasheet, IKW40N65H5AXKSA1 pinout, IKW40N65H5AXKSA1 application, or IKW40N65H5AXKSA1 equivalent, key selection criteria include gate charge (92 nC), switching energy (0.50 mJ total at 20A), diode reverse recovery (75 ns trr at 25°C), and thermal resistance (0.60 K/W j-c for IGBT).

Technical Context

This DuoPack device integrates a fifth-generation trench-gate field-stop IGBT and a soft-recovery silicon diode in a single TO-247-3 housing. The IGBT uses optimized carrier lifetime control and low-Q_G gate structure to minimize turn-on loss and tail current, while the diode features graded doping and lifetime control for low Q_rr and controlled dI_rr/dt.

It operates under hard-switching conditions up to 175°C junction temperature with validated SOA up to 120A pulsed collector current. The 0.60 K/W IGBT-to-case thermal resistance enables 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 650V in industrial DC/DC and charger topologies.
I_C	40 A continuous - Rated for 40A at T_C = 25°C; derates to 46A at T_C = 100°C per datasheet curve.
V_CE(sat)	1.66 V @ 40A, 25°C - Low conduction loss improves efficiency in medium-power SMPS stages.
Q_G	92 nC - Enables fast, low-loss switching with moderate gate drive strength (e.g., 15Ω RG).
E_ts	0.50 mJ @ 20A, 400V - Total switching energy defines thermal load during PWM operation at typical frequencies.
trr	75 ns @ 20A, 25°C - Fast, soft diode recovery reduces voltage overshoot and EMI in synchronous rectification.
R_th(j-c) (IGBT)	0.60 K/W - Allows direct heatsink mounting with predictable thermal drop for thermal design.

Pinout & Package

Package: PG-TO247-3 - Isolated case, through-hole mounting, metal tab for thermal conduction and electrical connection to collector.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; requires 15V ±20V rating; 92 nC total charge defines driver sizing.
Pin 2 + Backside	Collector	Main power input; electrically connected to metal tab; must be isolated from heatsink unless system ground referenced.
Pin 3	Emitter	Power return path; internal emitter bond wires define LE = 13 nH, critical for snubberless layout.

Key Features

Feature	Design Value
TRENCHSTOP™ 5 IGBT + RAPID 1 diode integration	DuoPack eliminates discrete pairing mismatch, reduces PCB area, and ensures matched thermal tracking between switch and freewheeling path.
175°C maximum junction temperature	Enables higher power density and extended operation in convection-cooled or high-ambient environments without derating.
Low V_CE(sat) and Q_G	Reduces both conduction and switching losses simultaneously-critical for >50 kHz hard-switched PFC and LLC stages.
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and UIS stress-suitable for EV onboard chargers.
Green RoHS-compliant package	Meets EU Directive 2011/65/EU; lead-free terminations and halogen-free molding compound support environmental compliance programs.

Industrial Motor Drive

Solar Inverter

Use Scenario: 3-phase inverter stage in 5–15 kW variable-frequency drives for pumps and HVAC compressors.

IC Role / Device Role / Timing Role: Half-bridge leg switch handling 40A RMS output current with 175°C thermal headroom.

Use Value: 120A pulsed collector rating and 175°C junction rating allow short-term overload tolerance during motor startup.

Use Scenario: String-level DC/AC conversion in residential solar inverters using three-level NPC or T-type topologies.

IC Role / Device Role / Timing Role: High-side switch in split-capacitor leg, requiring low Q_rr and soft recovery to limit dv/dt stress.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES5XKSA1	Same 650V/40A rating but uses TRENCHSTOP™ 5 Enhanced Speed (ES5) technology; lower V_CE(sat) (1.55 V) but higher Q_G (110 nC); no AEC-Q101 qualification.	Optimized for ultra-high-efficiency 100+ kHz resonant converters where conduction loss dominates; less suitable for automotive OBC due to missing qualification.	Select when prioritizing lowest possible conduction loss and thermal margin exceeds 150°C; verify gate driver capability for higher Q_G.
FGH40N60UFDTU	600V/40A fourth-generation IGBT with UltraFast diode; V_CE(sat) = 1.8 V; Q_G = 75 nC; R_th(j-c) = 0.75 K/W; not AEC-Q101 qualified.	Lower voltage rating limits use to ≤400V DC bus; softer diode recovery than RAPID 1 but higher Q_rr (1.1 µC); suited for cost-sensitive industrial UPS.	Select for 600V-class systems where lower gate charge eases driver design and AEC-Q101 is not required.

Compared with IKW40N65ES5XKSA1 and FGH40N60UFDTU, IKW40N65H5AXKSA1 balances low switching loss, automotive qualification, and 650V robustness-making it optimal for EV onboard chargers and industrial DC/DC where reliability and voltage margin are critical.

FAQ

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

The datasheet specifies RG(on) = RG(off) = 15 Ω for test conditions yielding 0.50 mJ total switching energy. For 40A operation, a 10–22 Ω range maintains safe dv/dt (<50 V/ns) and di/dt control while avoiding excessive switching loss. Lower values increase peak gate current and require ≥2A driver capability.

Is the backside collector electrically isolated from the package tab?

No-the backside metal tab is directly connected to Pin 2 (collector) and forms the primary thermal and electrical path for collector current. Electrical isolation from the heatsink requires insulating thermal pads or ceramic washers; failure to isolate may cause short circuits in non-grounded heatsink configurations.

Does this device support unclamped inductive switching (UIS) testing?

Yes-Infineon qualifies IKW40N65H5AXKSA1 per AEC-Q101, which includes UIS stress testing. The device supports 120A pulsed collector current at V_CE ≤ 650V and T_vj ≤ 175°C, enabling robust operation during transient overloads without external clamping circuitry.

Can the integrated diode replace an external fast recovery diode in synchronous rectification?

Yes-the RAPID 1 diode is designed for antiparallel use and provides soft, low-Q_rr recovery (0.52 µC at 20A). It eliminates need for external diodes in half-bridge or full-bridge configurations, provided layout minimizes stray inductance to avoid voltage overshoot during reverse recovery.
