Product details
Overview
IRGP4790PBF from Infineon Technologies (formerly International Rectifier) is a 650 V, 140 A (TC = 25°C), n-channel Insulated Gate Bipolar Transistor in TO-247AC package, optimized for high-efficiency switching in hard-switched industrial inverters and UPS systems with low VCE(on) of 1.7 V @ 75 A and 5.5 µs short-circuit SOA.
For engineers reviewing the IRGP4790PBF datasheet, IRGP4790PBF pinout, IRGP4790PBF application, or IRGP4790PBF equivalent, key selection criteria include its RBSOA-rated clamped inductive load current of 300 A, junction-to-case thermal resistance of 0.33 °C/W, positive VCE(on) temperature coefficient for parallel operation, and lead-free RoHS-compliant construction.
Technical Context
This IGBT employs a trench-gate field-stop structure enabling low conduction loss and robust short-circuit withstand capability. Its 5.5 µs short-circuit safe operating area (SCSOA) at TJ = 150°C and VCC = 400 V supports reliable fault handling in motor drive protection circuits.
The device features a square reverse bias SOA up to 175°C with full-rated VCE = 650 V and IC = 300 A, enabled by controlled minority carrier lifetime and optimized doping profiles. Its gate threshold voltage (5.5–7.4 V) and negative VGE(th) temperature coefficient ensure stable turn-on behavior across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 650 V - Maximum blocking voltage before avalanche; enables use in 400 V DC bus industrial inverters with 1.6× safety margin. |
| IC (TC = 25°C) | 140 A - Continuous collector current rating at case temperature 25°C; defines maximum steady-state output power capability. |
| VCE(on) | 1.7 V (typ.) @ 75 A, 15 VGE, 25°C - Low saturation voltage reduces conduction loss and improves system efficiency above 10 kHz switching. |
| tSC | 5.5 µs - Short-circuit withstand time at TJ = 150°C, VCC = 400 V; enables deterministic overcurrent protection without desaturation circuitry. |
| RθJC | 0.33 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting with minimal thermal interface resistance for 455 W dissipation at 25°C case. |
| Qg | 140–210 nC - Total gate charge; determines required gate driver peak current (≥14 A for 10 ns rise time) and influences Eon/Eoff trade-off. |
| Etotal | 4.7–6.4 mJ @ 75 A, 400 V - Total switching energy per cycle; sets minimum practical switching frequency for thermal management in 10–20 kHz applications. |
Pinout & Package
IRGP4790PBF is housed in a TO-247AC package with isolated metal tab, designed for direct heatsink mounting and high-current PCB routing. The three-terminal configuration supports standard IGBT gate drive and power path layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control input | Receives ±20 V gate drive signal; requires 140–210 nC total charge for full turn-on; sensitive to dV/dt-induced false triggering. |
| C (Collector) | High-side power output | Carries main load current (up to 300 A pulsed); connected to DC bus positive; electrically tied to heatsink via isolated tab. |
| E (Emitter) | Power return / reference | Serves as common emitter node for current sensing and gate drive return; low-inductance layout critical for switching stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(on) and switching losses | 1.7 V saturation voltage and 4.7–6.4 mJ total switching energy enable >98% efficiency in 15 kHz solar inverter half-bridges. |
| 5.5 µs short-circuit SOA | Guarantees safe shutdown under bolted fault conditions without external desaturation detection in motor drive gate drivers. |
| Positive VCE(on) temperature coefficient | Enables stable current sharing in paralleled configurations without active current balancing circuitry. |
| Rugged RBSOA | Full 650 V × 300 A square safe operating area at 175°C supports unclamped inductive switching in welding power supplies. |
| Lead-free, RoHS-compliant | Meets IPC-J-STD-020D reflow profile requirements for Pb-free assembly; eliminates post-soldering contamination concerns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current IGBT applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN120N60B3 | 600 V rating, 120 A IC, lower Qg (110 nC), but no specified tSC rating | Limited to ≤400 V DC bus; unsuitable for 650 V solar inverter designs requiring full-voltage SCSOA | Select only for cost-sensitive 600 V UPS where short-circuit immunity is managed externally |
| STMicroelectronics STGW40H65DFB | 650 V, 40 A IC, integrated freewheeling diode, higher VCE(on) (1.9 V) | Targeted at lower-power (<5 kW) motor drives; insufficient current rating for 140 A industrial inverters | Use only in space-constrained designs where integrated diode simplifies layout and power level is ≤15 kW |
Compared with IXGN120N60B3 and STGW40H65DFB, IRGP4790PBF uniquely delivers 650 V blocking, 140 A continuous current, and verified 5.5 µs short-circuit withstand-making it the sole choice for high-reliability 10–100 kW industrial inverters demanding full-voltage fault tolerance.

FAQ
What is the maximum gate-emitter voltage rating for IRGP4790PBF?
The absolute maximum continuous gate-to-emitter voltage is ±20 V. Exceeding this limit risks permanent gate oxide damage. Gate drive circuits must clamp transient overshoot using Zener diodes or active clamping, especially during high-dI/dt switching in paralleled configurations.
Does IRGP4790PBF include an integrated freewheeling diode?
No. IRGP4790PBF is a discrete IGBT without an integrated body diode. External ultrafast freewheeling diodes-such as the IRFP4668PbF-are required in inverter leg configurations to handle reactive current commutation and reverse recovery energy.
How does the positive VCE(on) temperature coefficient improve reliability?
The positive coefficient causes VCE(on) to increase with junction temperature, naturally limiting current in paralleled devices. This self-balancing effect prevents thermal runaway and eliminates need for external emitter resistors or active current-sharing circuits in multi-module systems.
What thermal interface material is recommended for TO-247AC mounting?
A thermally conductive, electrically insulating grease (e.g., Dow Corning TC-5123) with 1.5–2.5 W/m·K conductivity and <0.1 mm bond line thickness is recommended. Avoid silicone-free pastes that dry out; verify compatibility with aluminum heatsinks and conformal coating processes.
