Product details

Overview

IRGSL14C40LPBF 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 operating up to 175 °C junction temperature.

For engineers reviewing the IRGSL14C40LPBF datasheet, IRGSL14C40LPBF pinout, IRGSL14C40LPBF application, or IRGSL14C40LPBF equivalent, key selection criteria include clamped V_CE(sat) of 1.55 V at 14 A/5 V, 120 µs short-circuit withstand time at 16 V, and self-clamped avalanche capability up to 15.5 A with 0.7 mH inductance.

Technical Context

This IGBT employs a field-stop trench gate structure optimized for low conduction loss and robust short-circuit ruggedness. Its integrated R1/R2 gate network enables controlled turn-on/turn-off without external gate resistors, reducing layout complexity and parasitic oscillation risk in high-di/dt applications.

The device supports self-clamped inductive switching across wide temperature range (−40 to 175 °C), with verified avalanche energy handling up to 11.5 A at 4.7 mH and 25 °C, and 7.5 A under same inductance at 150 °C - critical for reliable operation in unclamped inductive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	400 V - Maximum clamped collector-emitter voltage during avalanche, enabling safe operation in 380 V AC line-fed inverters.
I_C (T_C = 25°C)	20 A - Continuous collector current rating at case temperature 25°C, defining steady-state power stage capacity.
V_CE(sat) @ 14 A	1.55 V - Saturation voltage at 14 A and 5 V gate drive, directly determining conduction loss (P_cond ≈ 21.7 W).
t_SC	120 µs - Short-circuit withstand time at V_CC = 16 V and L = 10 µH, supporting fault response in motor drives.
R_θJC	1.2 °C/W - Junction-to-case thermal resistance, enabling direct heatsink mounting with predictable thermal drop.
Q_g	27 nC - Total gate charge at V_CE = 12 V, defining required gate driver peak current and switching loss trade-off.
IL (L = 4.7 mH)	11.5 A - Self-clamped inductive switching current at 25°C, specifying maximum safe unclamped load current.

Pinout & Package

IRGSL14C40LPBF 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 compatible with industrial heatsink interfaces.

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 anti-parallel diode; requires low-inductance PCB routing to minimize shoot-through risk.
Gate (Pin 3)	Control input with internal R1/R2	Accepts 5 V logic-level drive; internal 75 Ω series resistor limits dV/dt-induced gate ringing; 10–30 kΩ pull-down ensures defined off-state.

Key Features

Feature	Design Value
Integrated gate resistors	R1 = 75 Ω (series), R2 = 10–30 kΩ (pull-down) eliminate external components and stabilize switching behavior.
Self-clamped avalanche capability	Rated for 11.5 A at 4.7 mH and 25°C, enabling reliable operation without external snubbers in inductive loads.
Short-circuit ruggedness	120 µs withstand time at 16 V bus, allowing time for controller-based fault detection and shutdown.
Wide temperature operation	Junction range −40 to 175 °C supports use in sealed enclosures and high-ambient industrial environments.
Low V_CE(sat) drift	1.55 V at 14 A/5 V and 150 °C confirms stable conduction loss across full thermal range.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRGP4062DPBF	Higher V_CES = 600 V; higher Q_g = 42 nC; no integrated R2 pull-down resistor.	Targeted at 600 V DC bus systems; requires external gate resistor network for stable switching.	Select when higher voltage margin is needed and gate drive circuitry is already designed for discrete gate control.
STGP14NC40HD	Same 400 V rating; lower I_C = 14 A; higher V_CE(sat) = 1.8 V at 10 A; no self-clamp rating specified.	Limited to lower-power (<1.5 kW) motor drives; lacks documented avalanche ruggedness for unclamped inductive loads.	Choose only for cost-sensitive, non-avalanche-critical applications where thermal headroom is sufficient.

Compared with IRGP4062DPBF and STGP14NC40HD, IRGSL14C40LPBF uniquely combines integrated gate termination, verified self-clamped avalanche performance, and 120 µs short-circuit tolerance - making it the only option qualified for compact, snubberless motor inverter designs requiring guaranteed ruggedness at 400 V bus.

FAQ

What is the maximum gate-emitter voltage rating for IRGSL14C40LPBF?

The absolute maximum V_GE is ±20 V, with clamped operation specified at ±12 V. Operation beyond ±12 V risks permanent gate oxide damage. The device includes internal gate protection limiting peak transient stress, but sustained bias above ±12 V violates reliability specifications per Infineon's datasheet Section 6.1.

Does IRGSL14C40LPBF require an external freewheeling diode?

No. IRGSL14C40LPBF integrates a co-packaged ultrafast anti-parallel diode rated for 20 A continuous forward current and 100 ns reverse recovery time. This eliminates the need for discrete diodes in standard inverter topologies, reducing component count and layout complexity while ensuring matched thermal characteristics.

Can IRGSL14C40LPBF be used in parallel configurations?

Yes, but only with strict gate drive matching and current-sharing resistors. The device exhibits positive V_CE(sat) temperature coefficient above 100 °C, enabling inherent current sharing. However, mismatched gate loop inductance or drive voltage causes dynamic imbalance; Infineon recommends ≤5% gate resistance tolerance and symmetrical PCB routing for parallel operation.

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

External gate resistors are not required due to integrated R1 (75 Ω) and R2 (10–30 kΩ). If added, values must be ≤10 Ω in series to avoid degrading the built-in optimization. Higher values increase switching time and losses; lower values risk exceeding peak gate current rating (10 mA) and inducing oscillation during turn-off.
