Product details
Overview
IGW25T120FKSA1 from Infineon is a 1200 V, 25 A low-loss NPT IGBT in TrenchStop® and Fieldstop technology, optimized for hard-switched industrial inverters and UPS systems. It delivers 1.7 V VCE(sat) at 25 °C, 10 µs short-circuit withstand time, and 155 nC total gate charge - enabling high-efficiency, thermally stable operation up to 150 °C junction temperature.
For engineers reviewing the IGW25T120FKSA1 datasheet, IGW25T120FKSA1 pinout, IGW25T120FKSA1 application, or IGW25T120FKSA1 equivalent, key selection criteria include its positive VCE(sat) temperature coefficient for parallel operation, tight parameter distribution, low EMI profile, and JEDEC J-STD-020 qualification for frequency converters and uninterruptible power supplies.
Technical Context
This IGBT employs Non-Punch-Through (NPT) structure with TrenchStop® gate trenching and Fieldstop drift layer, delivering robust short-circuit ruggedness and stable dynamic performance across -40 °C to +150 °C. Its positive VCE(sat) temperature coefficient ensures current sharing in paralleled configurations without external balancing resistors.
The device integrates an 8 Ω internal gate resistor and exhibits 1860 pF input capacitance (Ciss) at 25 V, supporting predictable turn-on/turn-off timing with external gate drivers. Switching energy remains stable under varying VCE, junction temperature, and gate resistance - critical for fixed-frequency inverter topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE | 1200 V - supports DC bus voltages up to 960 V in 3-phase inverters with 20 % safety margin |
| IC (continuous) | 25 A at TC = 100 °C - enables compact heatsink design in 5–10 kW UPS modules |
| VCE(sat) | 1.7 V @ Tj = 25 °C - reduces conduction loss by ~15 % vs. comparable 1200 V IGBTs |
| tSC | 10 µs @ VGE = 15 V - allows reliable overcurrent protection response in digital gate drivers |
| Qgate | 155 nC - determines gate driver peak current requirement (~3 A for 50 ns rise time) |
| RthJC | 0.65 K/W - defines thermal path efficiency from junction to case, critical for thermal derating |
| Eoff | 4.0 mJ @ Tj = 150 °C - sets switching loss budget for 4–16 kHz inverter operation |
Pinout & Package
IGW25T120FKSA1 uses the PG-TO-247-3 package: insulated plastic housing with 3 leads, creepage/clearance compliant for 1200 V isolation, and screw-mount compatible case for forced-air or heatsink cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-side power terminal | Connected to DC+ bus; carries full load current and must be routed with low-inductance layout |
| Gate (G) | Control input | Driven by isolated gate driver; requires <100 Ω series resistance to damp ringing due to 1860 pF Ciss |
| Emiter (E) | Power return and reference node | Serves as common emitter for IGBT and anti-parallel diode; must be low-impedance to minimize VCE measurement error |
Key Features
| Feature | Design Value |
|---|---|
| TrenchStop® + Fieldstop architecture | Enables 1200 V blocking with <1.7 V VCE(sat) and <10 µs short-circuit capability - no trade-off between voltage rating and conduction loss |
| Positive VCE(sat) temperature coefficient | Ensures natural current sharing in multi-device parallel configurations without external emitter resistors or active balancing |
| JEDEC J-STD-020 qualified | Validated for reflow soldering up to 260 °C (10 s), ensuring reliability in automated SMT assembly of power modules |
| Low EMI signature | Controlled dV/dt (via 8 Ω RG(int)) and soft tail current reduce conducted noise in EMC-sensitive UPS and servo drives |
| Pb-free, RoHS-compliant plating | Meets EU Directive 2011/65/EU and IPC-J-STD-609A Class 1 requirements for industrial and medical equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN25N120B3 | 1200 V, 25 A; higher VCE(sat) (2.0 V); lower Qgate (120 nC); TO-247-3 package | Better suited for higher-frequency resonant topologies where gate drive loss dominates | Select when prioritizing gate drive efficiency over conduction loss in >15 kHz designs |
| STMicroelectronics STGW25H120DF2 | 1200 V, 25 A; integrated freewheeling diode; same VCE(sat) (1.7 V); higher Eoff (5.1 mJ) | Optimized for space-constrained single-package solutions requiring co-packaged diode | Choose when eliminating discrete diode layout and reducing bill-of-material count is critical |
Compared with IXGN25N120B3 and STGW25H120DF2, IGW25T120FKSA1 offers superior thermal stability and tighter VCE(sat) distribution - making it preferred for paralleled arrays in high-reliability UPS and industrial drives where long-term parameter drift must be minimized.

FAQ
What is the maximum allowable gate-emitter voltage for IGW25T120FKSA1?
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, while negative bias below -10 V may cause unintended turn-on due to Miller coupling in high-dV/dt environments.
Does IGW25T120FKSA1 include an integrated anti-parallel diode?
No - IGW25T120FKSA1 is a standalone IGBT in a 3-pin TO-247 package without an integrated freewheeling diode. An external ultrafast soft-recovery diode (e.g., IDH12EG120, 1200 V/30 A) must be used in inverter legs to handle reverse recovery current and prevent shoot-through.
How does the 10 µs short-circuit withstand time translate into system-level protection design?
The 10 µs rating assumes VGE = 15 V, VCC ≤ 1200 V, and Tj ≤ 150 °C. System protection must detect overcurrent and disable gate drive within ≤8 µs to ensure safe turn-off before thermal runaway - requiring sub-microsecond comparator-based desaturation detection circuits.
Can IGW25T120FKSA1 be paralleled without external emitter resistors?
Yes - its positive VCE(sat) temperature coefficient ensures inherent current balancing across devices. Parallel operation requires matched gate drive loop inductance (<5 nH difference), identical PCB trace lengths, and symmetrical thermal mounting to maintain uniform junction temperature across all units.
