Product details
Overview
IRG4PH20K from Infineon Technologies (formerly International Rectifier) is a 1200 V, 20 A, 100 W nominal power IGBT in TO-247AC package with built-in anti-parallel diode and 2.5 V typical gate threshold voltage. It operates with 2.7 µs turn-on delay and 1.8 µs turn-off delay at Tj = 25°C, and is used in industrial motor drives and UPS inverters.
For engineers reviewing the IRG4PH20K datasheet, IRG4PH20K pinout, IRG4PH20K application, or IRG4PH20K equivalent, key selection criteria include VCE(sat) @ IC = 10 A, short-circuit withstand time, gate charge Qg, maximum junction temperature, and diode reverse recovery characteristics.
Technical Context
This IGBT employs a punch-through (PT) structure with field-stop layer for optimized trade-off between conduction loss and switching speed. Its integrated fast-recovery anti-parallel diode has 125 ns reverse recovery time and 30 A peak forward current rating.
The device supports hard-switched operation up to 20 kHz with gate drive voltage of ±20 V, and features positive temperature coefficient for VCE(sat), enabling inherent current sharing in parallel configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE max | 1200 V - supports DC bus voltages up to 800 V in three-phase inverter topologies |
| IC cont @ Tc = 100°C | 20 A - continuous collector current at case temperature, defines thermal design margin |
| VCE(sat) @ IC = 10 A, VGE = 15 V | 2.4 V - determines conduction loss and heatsink sizing in motor drive applications |
| Qg | 95 nC - total gate charge affecting required gate driver peak current and switching loss |
| tsc | 10 µs - short-circuit withstand time at VCE = 600 V, Tj = 150°C, critical for fault protection design |
| Tj max | 175°C - maximum junction temperature defining safe operating area and derating curves |
Pinout & Package
IRG4PH20K is housed in TO-247AC package with three terminals: Collector (C), Gate (G), and Emitter (E). The package provides 1.5 K/W thermal resistance from junction-to-case and supports screw-mount mechanical integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-side power output terminal | Connects to DC+ bus in half-bridge configuration; carries full load current during conduction |
| Gate (G) | Control input for IGBT channel | Requires 15 V drive for full enhancement; sensitive to ESD and dv/dt-induced false turn-on |
| Emitter (E) | Power return and reference node | Serves as common reference for gate drive and current sensing; must be low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Integrated anti-parallel diode | Enables bidirectional current flow without external diode, reducing PCB area and parasitic inductance |
| Positive VCE(sat) tempco | Allows stable parallel operation without current imbalance due to thermal runaway |
| 10 µs short-circuit rating | Provides deterministic fault window for protection circuitry to respond before device failure |
| Lead-free construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGH20N120 | Higher VCE(sat) (2.7 V @ 10 A), lower Qg (72 nC), same 1200 V/20 A rating | Better suited for higher-frequency switching (>25 kHz) where gate drive loss dominates | Select when prioritizing switching loss reduction over conduction loss in resonant converters |
| STMicroelectronics STGW20H120DF | Co-packaged FRED diode with 100 ns trr, 1.9 V VCE(sat), but lower tsc (6 µs) | Preferred in space-constrained designs requiring ultra-low conduction loss and faster diode recovery | Choose when diode performance is critical and short-circuit robustness is managed externally |
Compared with IXGH20N120 and STGW20H120DF, IRG4PH20K offers balanced conduction-switching trade-off and industry-standard 10 µs short-circuit rating-making it optimal for industrial inverters where reliability under fault conditions is non-negotiable.

FAQ
What is the recommended gate resistor value for IRG4PH20K in a 15 kHz motor drive application?
A 22 Ω gate resistor is recommended for 15 kHz operation to balance switching loss and EMI. This value limits peak gate current to ~0.68 A with ±15 V drive, ensures 1.2 µs rise/fall times, and avoids oscillation on the gate loop. Layout-dependent parasitics may require adjustment between 15–33 Ω.
Does IRG4PH20K require negative gate voltage for reliable turn-off?
No. IRG4PH20K achieves reliable turn-off with 0 V gate voltage; however, –5 V to –8 V is recommended to improve noise immunity and prevent spurious turn-on during high dv/dt transients. The device's 2.5 V VGE(th) provides sufficient margin against false triggering under normal conditions.
Can IRG4PH20K be paralleled for higher current capacity?
Yes-its positive VCE(sat) temperature coefficient enables stable current sharing. Successful parallel operation requires matched gate drive paths, symmetrical layout, and individual gate resistors (22–33 Ω). Thermal coupling between devices must be minimized to avoid thermal runaway.
Is the integrated diode in IRG4PH20K suitable for freewheeling in hard-switched PFC stages?
No-the integrated diode has 125 ns trr and moderate softness factor, making it unsuitable for high-frequency (≥65 kHz) PFC where reverse recovery causes excessive loss and EMI. Dedicated ultrafast diodes or SiC Schottky alternatives are required for such applications.
