Product details

Overview

IKW40N60H3FKSA1 from Infineon Technologies is a 600 V, 40 A high-speed DuoPack IGBT with integrated soft-recovery anti-parallel diode in Trench and Fieldstop technology. It delivers 1.95 V V_CE(sat) at 40 A and 25°C, operates up to 175°C junction temperature, and targets high-frequency industrial power converters requiring low conduction loss and controlled EMI.

For engineers reviewing the IKW40N60H3FKSA1 datasheet, IKW40N60H3FKSA1 pinout, IKW40N60H3FKSA1 application, or IKW40N60H3FKSA1 equivalent, key selection criteria include its 223 nC gate charge, 1.50 K/W diode thermal resistance, 124 ns diode reverse recovery time at 25°C, and PG-TO247-3 package compatibility with high-power heatsink mounting.

Technical Context

This IGBT uses Infineon's TRENCHSTOP™ third-generation process, combining trench-gate structure and field-stop layer to achieve low V_CE(sat) (1.95 V) and reduced switching losses. Its integrated diode features soft, fast recovery (trr = 124 ns typ. at 25°C) and low Q_rr (0.81 µC), minimizing voltage overshoot and snubber stress.

The device supports pulsed collector current up to 160 A and short-circuit withstand time of 5 µs at 150°C junction temperature. Thermal design is enabled by separate IGBT and diode junction-to-case thermal resistances (0.49 K/W and 1.50 K/W), allowing independent thermal path optimization in converter topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - Maximum blocking voltage for DC-link applications up to 400 V bus with safety margin.
I_C	40 A continuous - Rated collector current at T_C = 100°C, enabling compact 3–5 kW inverter designs.
V_CE(sat)	1.95 V at 40 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in hard-switched converters.
t_SC	5 µs - Short-circuit ruggedness enables reliable operation in UPS and welding systems without external desaturation protection.
trr	124 ns at 25°C - Fast, soft diode recovery limits dv/dt-induced turn-on and reduces EMI filter size.
R_th(j-c) (Diode)	1.50 K/W - Enables direct thermal coupling to heatsink for diode loss management in bidirectional energy flow.
Q_G	223 nC - Gate drive power requirement informs selection of gate driver ICs (e.g., 1ED020I12FA) with ≥2 A peak output.

Pinout & Package

IKW40N60H3FKSA1 is housed in a PG-TO247-3 package with isolated tab, optimized for high-current, high-voltage industrial mounting. The case serves as the collector terminal, ensuring low-inductance connection to the DC-link capacitor.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Collector)	Main power output terminal (IGBT)	Connected to DC-link positive; electrically tied to metal tab for low-inductance, high-current path.
Pin 2 (Gate)	Control input for IGBT channel	Requires 15 V ±5 V drive; 223 nC total gate charge demands robust gate resistor (e.g., 7.9 Ω) for controlled switching.
Pin 3 (Emitter)	Common emitter for IGBT and diode	Reference node for gate drive and current sensing; shared emitter path necessitates Kelvin emitter layout for accurate control.

Key Features

Feature	Design Value
TRENCHSTOP™ III technology	Enables 1.95 V V_CE(sat) at 40 A while maintaining 5 µs short-circuit capability-reducing heatsink size by ~25% vs. prior gen.
Soft, fast-recovery anti-parallel diode	trr = 124 ns and Q_rr = 0.81 µC at 25°C minimize reverse recovery losses and enable >20 kHz switching in PFC stages.
175°C maximum junction temperature	Supports derated operation at elevated ambient temperatures (e.g., enclosed UPS cabinets) without forced air cooling.
Pb-free, RoHS-compliant plating	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements before reflow assembly.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES5XKSA1	650 V rating, lower V_CE(sat) (1.75 V), higher Q_G (250 nC), same PG-TO247-3 package	Better suited for 600 V DC-link systems with tighter voltage margins; higher gate drive demand increases driver cost	Select when system DC-link exceeds 450 V or higher blocking margin is required without changing footprint.
FGB3040G2	600 V, 40 A, V_CE(sat) = 2.1 V, trr = 150 ns, TO-247-3 package, no JEDEC qualification	Higher conduction loss and slower diode recovery increase thermal stress and EMI filtering burden	Consider only for cost-sensitive, non-safety-critical industrial controls where qualification traceability is not mandated.

Compared with IKW40N60H3FKSA1, IKW40N65ES5XKSA1 offers higher voltage headroom but requires stronger gate drivers, while FGB3040G2 trades off reliability and soft-switching performance for lower acquisition cost-making the original optimal for certified UPS and welding equipment.

FAQ

What is the maximum recommended gate resistor value for IKW40N60H3FKSA1 in a 20 kHz inverter?

The datasheet specifies r_G = 7.9 Ω for test conditions (V_CC = 400 V, I_C = 40 A). At 20 kHz, a 10–15 Ω gate resistor balances switching loss and EMI; values above 22 Ω risk excessive turn-off delay (>250 ns) and increased E_off, especially at 175°C junction temperature.

Can IKW40N60H3FKSA1 be used in a three-phase inverter without external freewheeling diodes?

Yes-the integrated soft-recovery anti-parallel diode is rated for 40 A continuous (T_C = 25°C) and 20 A (T_C = 100°C), making it suitable for freewheeling in standard three-phase motor drives up to 15 kW. Layout must ensure low-inductance emitter return paths to avoid shoot-through during commutation.

Does IKW40N60H3FKSA1 require negative gate voltage for reliable turn-off?

No-turn-off is fully functional with 0 V gate drive. However, applying –5 V to –10 V improves noise immunity and reduces Miller-induced false turn-on in high-dv/dt environments (e.g., >500 V/µs). The gate-emitter voltage rating is ±20 V, supporting safe negative bias implementation.

How does thermal resistance differ between the IGBT and diode dies inside the DuoPack?

The IGBT die has R_th(j-c) = 0.49 K/W, while the diode die has R_th(j-c) = 1.50 K/W-reflecting different die sizes and thermal path geometries. This asymmetry requires thermal interface material and heatsink design to accommodate higher diode junction temperature rise under regenerative braking or inverter freewheeling conditions.
