Product details

Overview

IRGC4274B from Infineon Technologies (formerly International Rectifier) is a 650 V, 150 A trench gate field-stop IGBT die with integrated 1.9 Ω gate resistor, rated for 175 °C junction temperature and short-circuit withstand time of 6 μs at 150 °C. It delivers low V_CE(on) (1.6 V typ. @ 150 A, 25 °C) and low switching losses, targeting high-efficiency industrial motor drives and UPS inverters.

For engineers reviewing the IRGC4274B datasheet, IRGC4274B pinout, IRGC4274B application, or IRGC4274B equivalent, key selection criteria include its wafer-level form factor, verified SCSOA performance under 400 V bus conditions, tight parameter distribution across wafers, and suitability for parallel operation in high-current power modules.

Technical Context

This IGBT die employs trench-gate field-stop architecture with optimized carrier lifetime control to achieve simultaneous low conduction loss and fast switching. Its positive V_CE(on) temperature coefficient ensures stable current sharing in parallel configurations without external emitter resistors.

The integrated 1.9 Ω gate resistor (±0.5 Ω) is laser-trimmed on-die and enables consistent turn-on/turn-off timing across units, reducing layout sensitivity and gate drive design complexity. Die-level characterization confirms RBSOA compliance at V_CC = 480 V and SCSOA at V_GE = 15 V, V_CC = 400 V, T_J = 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE Rating	650 V - supports 400 V DC bus systems with 1.6× safety margin
I_C (DC)	150 A - rated continuous collector current at T_J = 150 °C with heatsink
V_CE(on)	1.6 V typ. @ 150 A, 25 °C - enables <1.5 W conduction loss per device at rated current
SCSOA Time	6 μs @ V_CC = 400 V, T_J = 150 °C - allows robust short-circuit protection window for gate driver response
R_G(int)	1.9 Ω ±0.5 Ω - integrated, trimmed gate resistor reduces external component count and layout variability
T_J(max)	175 °C - extends thermal headroom for high ambient or high-power-density designs
C_iss	9900 pF @ V_CE = 30 V - defines gate drive energy requirement and Miller effect sensitivity

Pinout & Package

IRGC4274B is supplied as a bare die (no leadframe or molded package) in wafer or singulated form. Die dimensions are 8.74 × 8.74 mm² with aluminum front metallization (0.1 μm Ti/0.1 μm Ni/0.6 μm Ag) and silver-sinterable backside metallization. Terminal structure consists of three exposed metal pads: Emitter (larger rectangular pad), Collector (full backside), and Gate (smaller rectangular pad adjacent to emitter).

Pin/Terminal	Circuit Role	Design Meaning
Emitter Pad	Main current return path and reference node for gate drive	0.7 × 1.7 mm² Al/Ni/Ag pad - low-inductance connection critical for switching stability
Collector (Backside)	Main high-current output terminal	Full 8.74 × 8.74 mm² silver-sinterable surface - enables low thermal resistance to heatsink
Gate Pad	Control input for MOS-controlled bipolar conduction	Small Al/Ni/Ag pad - requires precise gate drive routing to minimize ringing and overshoot

Key Features

Feature	Design Value
Square RBSOA	Guarantees safe operation up to V_CC = 480 V with controlled turn-off, enabling reliable snubberless designs
Tight Parameter Distribution	V_CE(on), V_GE(th), and Q_g variation < ±5% across wafer - simplifies parallel IGBT matching
Positive V_CE(on) Tempco	Enables inherent current balancing in multi-die modules without external emitter resistors
Short-Circuit Rated	6 μs withstand time at 400 V, 150 °C - provides deterministic fault-clearing window for gate driver ICs

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current IGBT die applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN150N60B3	600 V rating, 150 A, no integrated gate resistor, higher V_CE(on) (1.85 V typ.)	Requires external gate resistor tuning; less suitable for high-density parallel layouts	Preferred where gate drive loop inductance is tightly controlled and cost-per-wafer is prioritized
STMicroelectronics STGY150V60DF	650 V, 150 A, co-packaged with freewheeling diode, TO-247 packaged die	Not bare die - limits module integration flexibility and thermal interface options	Selected when discrete mounting and standard footprint compatibility outweigh bare-die thermal advantages

Compared with IXGN150N60B3 and STGY150V60DF, IRGC4274B uniquely combines wafer-level integration, on-die gate resistance, and verified 6 μs SCSOA - making it optimal for custom power modules demanding high reliability, parallel scalability, and thermal optimization.

FAQ

Is IRGC4274B supplied in tape-and-reel or surface-mount packaging?

No - IRGC4274B is a bare die product offered only in unsawn wafer, waffle pack, or film-mounted formats. It has no leadframe, molding compound, or standardized package outline. Mounting requires die-attach epoxy or solder and wire bonding or clip bonding to a substrate or DBC.

What is the maximum recommended gate drive voltage for IRGC4274B?

The absolute maximum gate-emitter voltage is ±20 V, but the recommended operating range is +15 V to –5 V. Driving above +15 V increases switching speed but risks gate oxide stress; below +13 V may cause incomplete saturation and elevated conduction loss.

Does IRGC4274B include an integrated freewheeling diode?

No - IRGC4274B is a single N-channel IGBT die without any integrated body diode or companion diode. External fast-recovery or SiC Schottky diodes must be used in inductive switching applications to provide commutation paths.

How is short-circuit withstand time validated for IRGC4274B?

SCSOA is verified via die-level characterization under V_GE = 15 V, V_CC = 400 V, R_G = 5 Ω, and T_J = 150 °C, measuring time-to-failure under clamped inductive load. The 6 μs value is not production-tested but confirmed through design simulation and wafer-level stress testing.
