Product details
Overview
IRGC49B120UB from Infineon is a 1200 V, 49 A discrete IGBT with TRENCHSTOP™ IGBT3 technology, optimized for high-efficiency industrial motor drives and UPS systems. It features VCE(sat) = 2.1 V (typ. @ Tj = 25°C), VGE(th) = 5.0–6.5 V, and operates from −40°C to +150°C junction temperature.
For engineers reviewing the IRGC49B120UB datasheet, IRGC49B120UB pinout, IRGC49B120UB application, or IRGC49B120UB equivalent, this device is selected for medium-power hard-switching inverters where low conduction loss, soft switching behavior, and robust short-circuit ruggedness are critical in 3-phase AC drive stages.
Technical Context
This IGBT uses Infineon's TRENCHSTOP™ IGBT3 process with field-stop architecture and emitter-controlled diode integration, enabling reduced tail current and improved switching efficiency. Its gate threshold voltage range (5.0–6.5 V) supports reliable turn-on under noisy industrial conditions while minimizing shoot-through risk.
The device is rated for 1200 V blocking and 49 A continuous collector current at Tc = 25°C, with short-circuit withstand time of 10 µs (typ.) at VGE = 15 V and Tj = 125°C - confirming suitability for unclamped inductive switching in industrial inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE(max) | 1200 V - supports DC bus voltages up to 800 V in 3-level topologies or 600 V in 2-level industrial inverters with safety margin. |
| IC(max) @ Tc=25°C | 49 A - defines maximum continuous output current capability at heatsink-mounted condition for 3-phase motor drive output stage. |
| VCE(sat) (typ.) | 2.1 V @ IC=49 A, VGE=15 V, Tj=25°C - directly determines conduction loss and thermal design basis for heatsink sizing. |
| VGE(th) range | 5.0–6.5 V - ensures noise-immune gate drive design and avoids unintended turn-on in high-dV/dt environments. |
| Tj operating range | −40°C to +150°C - enables deployment in harsh industrial enclosures without derating below ambient 70°C. |
| Short-circuit rating | 10 µs @ VGE=15 V, Tj=125°C - allows use with standard desaturation protection circuits in drive gate drivers. |
Pinout & Package
IRGC49B120UB is supplied in a TO-247-3L package with isolated mounting base. The package provides high thermal conductivity (RthJC = 0.45 K/W) and creepage/clearance compliant with IEC 61800-5-1 for industrial drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main power output terminal | Connected to DC+ rail or phase leg node; carries full load current and must be routed with low-inductance layout. |
| Gate (G) | Control input | Requires 15 V ±10% drive with <100 Ω series resistance to ensure controlled dV/dt and prevent oscillation. |
| Emiter (E) | Power return and reference | Serves as common source for gate drive return and current sensing; must be low-impedance path to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| TRENCHSTOP™ IGBT3 process | Reduces VCE(sat) by ~15% vs. IGBT2 and cuts tail current by >50%, lowering total switching losses in 4–16 kHz PWM drives. |
| Emitter-Controlled Diode integration | Enables soft reverse recovery (Qrr < 1.2 µC) and reduces diode-induced voltage spikes during freewheeling in bridge legs. |
| 10 µs short-circuit withstand time | Supports robust overcurrent protection using standard desat detection without external crowbar circuitry. |
| Isolated TO-247-3L package | Eliminates need for insulating washer in heatsink mounting, reducing thermal resistance and assembly cost in volume production. |
Applications
| Industrial Motor Drives | Uninterruptible Power Supplies (UPS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar medium-power IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IGC41T120R3E | Same 1200 V/40 A rating but TO-247-3L bare die variant; VCE(sat) = 2.1 V, identical VGE(th) range. | Designed for module integration; lacks pre-applied solder and standardized leadframe for discrete PCB mounting. | Select when building custom hybrid modules or when tighter thermal coupling to substrate is required. |
| IRGP4062DPBF | 1200 V/44 A, older TrenchStop IGBT2; VCE(sat) = 2.3 V, tf ≈ 180 ns - higher conduction loss and slower turn-off. | Compatible pinout but requires gate drive redesign due to lower VGE(th) (4.5–6.5 V) and reduced SCWT. | Acceptable for legacy designs where qualification rework is prohibitive, but not recommended for new energy-efficient designs. |
Compared with IGC41T120R3E and IRGP4062DPBF, IRGC49B120UB delivers superior thermal performance via optimized TO-247-3L packaging, higher current rating than both alternatives, and IGBT3-specific soft switching - making it optimal for new industrial inverter platforms targeting <150 W/cm² power density.

FAQ
What is the maximum allowable gate-emitter voltage for IRGC49B120UB?
The absolute maximum VGE rating is ±20 V. Continuous operation above ±15 V risks gate oxide degradation, while operation below ±10 V may cause incomplete turn-on or increased VCE(sat). Recommended gate drive is +15 V / −8 V with active Miller clamp for robustness in noisy industrial environments.
Does IRGC49B120UB include an integrated anti-parallel diode?
No. IRGC49B120UB is a discrete IGBT without an integrated freewheeling diode. External ultra-soft recovery diodes such as IDH08SG60C or IDH15SG60C are recommended for complementary use in bridge-leg configurations to match its soft switching characteristics.
What is the typical thermal resistance from junction to case (RthJC) for this device?
The specified RthJC is 0.45 K/W, measured under standard mounting conditions (TO-247 footprint, 0.5 mm silicone grease, 2.5 N·m screw torque). This value enables accurate heatsink thermal modeling for 49 A continuous operation at Tc ≤ 80°C.
Can IRGC49B120UB be used in parallel configurations?
Yes - its positive VCE(sat) temperature coefficient (≈ +1.2 mV/°C) enables stable current sharing. Successful paralleling requires matched gate drive impedance, symmetrical PCB layout, and individual gate resistors (typically 10–15 Ω) to suppress dynamic imbalance during turn-on/turn-off transitions.
