Product details
Overview
IGW40T120FKSA1 from Infineon is a 1200 V, 40 A low-loss NPT IGBT in TrenchStop® and Fieldstop technology, featuring 1.7 V VCE(sat) at Tj = 25°C, 10 µs short-circuit withstand time, and ±20 V gate-emitter voltage rating. It serves as the main switching device in high-voltage DC-AC conversion stages of industrial frequency converters and uninterruptible power supplies.
For engineers reviewing the IGW40T120FKSA1 datasheet, IGW40T120FKSA1 pinout, IGW40T120FKSA1 application, or IGW40T120FKSA1 equivalent, key selection criteria include VCE rating (1200 V), pulsed current capability (105 A), thermal resistance (RthJC = 0.45 K/W), gate charge (203 nC), and short-circuit ruggedness under 15 V gate drive.
Technical Context
This IGBT uses Non-Punch-Through (NPT) structure with TrenchStop® gate trenching and Fieldstop drift layer, delivering positive temperature coefficient for VCE(sat) - enabling stable parallel operation without current imbalance. Its 10 µs short-circuit withstand time is validated at VGE = 15 V, VCC ≤ 1200 V, and Tj ≤ 150°C.
Dynamic performance is optimized for hard-switched inductive loads: total switching energy is 6.5 mJ (Tj = 25°C) and 10.4 mJ (Tj = 150°C) at 600 V, 40 A, with gate charge of 203 nC and input capacitance of 2500 pF - supporting efficient 10–20 kHz operation in motor drives and UPS inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE | 1200 V - supports DC bus voltages up to 900 V in three-phase rectified systems with 25% safety margin. |
| IC (continuous) | 40 A at TC = 100°C - enables 5–7 kW output in forced-air-cooled 16 kHz inverter designs. |
| VCE(sat) | 1.7 V @ Tj = 25°C - reduces conduction loss to ~68 W at full load, critical for thermal management in compact enclosures. |
| tSC | 10 µs @ VGE = 15 V - allows time for fast overcurrent detection and shutdown in fault-tolerant UPS systems. |
| QG | 203 nC - determines gate driver peak current requirement (~13.5 A for 15 Ω gate resistor and 15 V drive). |
| RthJC | 0.45 K/W - enables junction-to-case temperature rise of ≤67.5 K at 150 W dissipation, guiding heatsink sizing. |
| Ets | 10.4 mJ @ Tj = 150°C - defines total switching loss per cycle at elevated temperature, directly impacting efficiency at full load. |
Pinout & Package
IGW40T120FKSA1 is housed in PG-TO-247-3 package - a through-hole, single-island thermally optimized variant with 3.8 mm creepage/clearance and 2.54 mm lead pitch. The case is electrically connected to the collector terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-side power output node | Connected to DC+ bus; carries full load current and must be mounted on heatsink via isolated mounting hardware. |
| Gate (G) | Control input for MOS-controlled bipolar conduction | Requires low-inductance gate loop; internal 6 Ω gate resistor limits dv/dt sensitivity and simplifies driver design. |
| Emitter (E) | Power return path and reference for gate drive | Serves as common source for gate driver supply; layout must minimize stray inductance (<13 nH specified) to suppress voltage overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| TrenchStop® + Fieldstop architecture | Enables tight parameter distribution (±5% VCE(sat)) and stable switching behavior across –40°C to +150°C junction range. |
| Positive VCE(sat) temperature coefficient | Permits reliable paralleling of multiple devices without external current-sharing resistors or active balancing circuits. |
| Low EMI generation | Controlled turn-off dv/dt (≤10 kV/µs typical) reduces filter component size and cost in EMI-compliant industrial inverters. |
| JEDEC J-STD-020 qualified | Guarantees robustness against moisture-induced popcorning during reflow soldering at 260°C for 10 s. |
| Pb-free, RoHS-compliant plating | Meets EU Directive 2011/65/EU and IPC-J-STD-609A Class 1 requirements for lead-free assembly compatibility. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN40N120B3 | 1200 V, 40 A; higher VCE(sat) (2.0 V typ.); lower QG (140 nC); TO-247-3 package | Better gate drive efficiency but higher conduction loss; less suitable for high-temperature continuous operation | Select when gate driver power budget is constrained and thermal margin exceeds 20 K. |
| STMicroelectronics STGW40H120DF2 | 1200 V, 40 A; soft-switching optimized; 1.85 V VCE(sat); built-in anti-parallel diode with low Qrr | Integrated diode eliminates discrete FRED pairing; higher switching loss than IGW40T120FKSA1 in hard-switched topologies | Prefer for resonant or ZVS designs where diode recovery stress dominates system reliability. |

FAQ
What is the maximum allowable gate-emitter voltage for reliable operation?
The absolute maximum gate-emitter voltage is ±20 V DC, with recommended operating range of –10 V to +15 V. Exceeding +15 V increases risk of gate oxide degradation over time, while negative bias below –10 V may cause unintended turn-on due to Miller coupling in high-di/dt environments.
Does IGW40T120FKSA1 include an integrated freewheeling diode?
No - IGW40T120FKSA1 is a standalone NPT IGBT in a 3-pin TO-247 package with no integrated body diode. An external ultrafast recovery diode (e.g., IDH08SG60C) must be used in antiparallel configuration for inductive load commutation.
How does the 10 µs short-circuit withstand time translate to system-level protection design?
The 10 µs rating assumes VGE = 15 V, VCC ≤ 1200 V, and Tj ≤ 150°C. System designers must implement overcurrent detection with ≤5 µs response time and gate turn-off within 8 µs to ensure safe shutdown before thermal runaway occurs.
Can IGW40T120FKSA1 be paralleled with identical units without external emitter resistors?
Yes - its positive temperature coefficient for VCE(sat) ensures inherent current sharing across devices. However, matched gate drive loop inductance (<5 nH difference) and symmetrical power layout remain essential to prevent dynamic current imbalance during switching transitions.
