Product details

Overview

IRGS14C40LPBF from Infineon Technologies is a 400 V, 20 A, 125 W trench-gate field-stop IGBT with integrated anti-parallel diode and built-in gate resistors (R1 = 75 Ω, R2 = 10–30 kΩ), designed for self-clamped inductive switching in motor control inverters and UPS systems. It delivers V_CE(sat) = 1.35–1.55 V at I_C = 10 A / V_GE = 4.5 V and supports short-circuit withstand time of 120 µs at T_J = 150 °C.

For engineers reviewing the IRGS14C40LPBF datasheet, IRGS14C40LPBF pinout, IRGS14C40LPBF application, or IRGS14C40LPBF equivalent, key selection criteria include clamped inductive current rating (11.5 A @ L = 4.7 mH), gate charge (Q_g = 27 nC), thermal resistance (R_θJC = 1.2 °C/W), and ESD robustness (6 kV HBM).

Technical Context

This IGBT employs a field-stop trench-gate structure enabling low conduction loss and fast switching with controlled dV/dt. Its integrated R1/R2 gate network eliminates external gate resistor placement while stabilizing turn-on/turn-off behavior under varying drive conditions.

The device features self-clamped avalanche capability up to 15.5 A (L = 0.7 mH) and is characterized for operation from –40 °C to 175 °C junction temperature, with validated short-circuit ruggedness under 16 V bus voltage and 10 µH inductance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	400 V - Maximum clamped collector-emitter voltage during inductive turn-off, defining safe operating area for motor drive snubberless operation
I_C (continuous, T_C = 25°C)	20 A - Continuous current handling at case temperature 25°C, supporting 1 kW-class inverter output stages
V_CE(sat) @ I_C = 10 A	1.35–1.55 V - Low saturation voltage enabling <1.6 W conduction loss per device at rated current
Q_g	27 nC - Total gate charge determining required driver peak current (≥10 mA) and switching energy
R_θJC	1.2 °C/W - Junction-to-case thermal resistance enabling direct heatsink mounting without thermal interface degradation
t_SC	120 µs - Short-circuit withstand time at V_CC = 16 V, allowing robust fault response in industrial motor drives
ESD Rating	6 kV HBM - Electrostatic discharge immunity sufficient for manual handling and board assembly without special precautions

Pinout & Package

IRGS14C40LPBF is housed in a TO-247AC package with three terminals: Collector (pin 1), Emitter (pin 2), and Gate (pin 3). The package features isolated mounting hole and standard lead-frame geometry for high-current PCB or heatsink attachment.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Pin 1)	High-side power switch node	Connects to DC bus positive; carries full load current and withstands 400 V clamped transients
Emiter (Pin 2)	Power return and reference node	Serves as common emitter for IGBT and integrated anti-parallel diode; requires low-inductance connection to DC bus negative
Gate (Pin 3)	Control input with internal R1/R2	Accepts 5 V logic-level drive; internal 75 Ω series resistor limits dv/dt, 10–30 kΩ pull-down ensures reliable turn-off

Key Features

Feature	Design Value
Integrated gate resistors	R1 = 75 Ω (series) + R2 = 10–30 kΩ (pull-down) eliminate external components and stabilize switching waveform shape
Self-clamped avalanche capability	Supports 11.5 A inductive current at L = 4.7 mH without external snubber, reducing system BOM and layout complexity
Field-stop trench-gate structure	Enables simultaneous optimization of V_CE(sat) and switching speed, achieving 27 nC Q_g with 1.35 V saturation
Short-circuit ruggedness	120 µs withstand time at 150 °C junction enables deterministic overcurrent protection without desaturation sensing
Lead-free and RoHS-compliant	Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 and EU RoHS Directive 2011/65/EU requirements

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGP14NC40KD	400 V / 14 A; no integrated gate resistors; higher V_CE(sat) (1.6 V typ); R_θJC = 1.4 °C/W	Requires external gate resistor network; lower current rating reduces margin in 2 kW motor drives	Select when cost sensitivity outweighs layout simplification and thermal margin needs
IXGH14N40C3	400 V / 14 A; non-field-stop planar structure; Q_g = 32 nC; t_SC = 10 µs only	Lacks self-clamp capability; requires external snubber; unsuitable for short-circuit tolerant designs	Choose only for fixed-frequency, low-stress resonant converters where ruggedness is secondary

Compared with STGP14NC40KD and IXGH14N40C3, IRGS14C40LPBF provides superior thermal performance (1.2 vs ≥1.4 °C/W), higher continuous current (20 A vs 14 A), and unique self-clamped operation-enabling snubberless inverter designs with enhanced reliability in overload conditions.

FAQ

What is the maximum allowable gate-emitter voltage for IRGS14C40LPBF?

The absolute maximum V_GE is ±20 V, but the device is characterized for reliable operation at V_GE = 5 V (turn-on) and V_GE = 0 V (turn-off). Exceeding ±12 V risks permanent gate oxide damage, and the integrated R2 resistor ensures stable 0 V bias during off-state.

Does IRGS14C40LPBF require an external freewheeling diode?

No. IRGS14C40LPBF integrates a co-packaged ultrafast anti-parallel diode with soft recovery characteristics, eliminating the need for discrete diodes in standard inverter topologies. This diode is rated for 20 A continuous forward current and matches the IGBT's thermal profile.

Can IRGS14C40LPBF be used in parallel configurations?

Yes, but with strict layout symmetry: matched gate drive paths, identical heatsink contact pressure, and current-sharing resistors (0.01–0.02 Ω) in emitter leads. The device's positive V_CE(sat) temperature coefficient enables inherent current balancing above 100 °C junction temperature.

What is the recommended gate resistor value when using external drive?

None required-the internal R1 (75 Ω) and R2 (10–30 kΩ) are optimized for standard 5 V logic drivers. Adding external series resistance increases switching losses and may destabilize turn-off; only low-inductance 0 Ω jumpers are advised if external buffering is used.
