Product details

Overview

IRGS14C40LTRLP from Infineon Technologies is a 400 V, 20 A, 1.55 V_CE(on) TRENCHSTOP™ IGBT with integrated gate resistor network (R1 = 75 Ω, R2 = 10–30 kΩ) and built-in avalanche ruggedness for self-clamped inductive switching up to 11.5 A at 4.7 mH and 25°C. It operates from –40°C to 175°C junction temperature and delivers 125 W power dissipation at T_C = 25°C, targeting motor control inverters in HVAC and industrial drives.

For engineers reviewing the IRGS14C40LTRLP datasheet, IRGS14C40LTRLP pinout, IRGS14C40LTRLP application, or IRGS14C40LTRLP equivalent, key selection criteria include clamped inductive current rating, gate threshold voltage stability over temperature, total gate charge (27 nC), thermal resistance (R_θJC = 1.2 °C/W), and integrated gate resistors enabling simplified drive design without external components.

Technical Context

This IGBT employs Infineon's TRENCHSTOP™ process for low conduction loss and robust short-circuit withstand (120 µs at V_CC = 16 V, L = 10 µH). Its monolithic integration of R1 and R2 provides controlled turn-on/turn-off dV/dt and reduces PCB layout sensitivity.

The device features a rated V_CES of 400 V, guaranteed BVCES min of 370 V, and exhibits stable V_GE(th) (1.3–2.2 V) across –40°C to 150°C. Its C_res (12–18 pF) and Q_gc (10 nC) support efficient high-frequency switching up to 20 kHz in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	400 V - Maximum clamped collector-emitter blocking voltage, enabling use in 300 V DC bus systems with margin.
I_C (T_C = 25°C)	20 A - Continuous collector current rating at case temperature 25°C, defining steady-state thermal design baseline.
V_CE(on)	1.55 V @ I_C = 14 A, V_GE = 5 V - Low saturation voltage directly reduces conduction losses in motor drive half-bridges.
Q_g	27 nC - Total gate charge determines required gate driver peak current and influences switching loss trade-offs.
R_θJC	1.2 °C/W - Junction-to-case thermal resistance enables accurate heatsink sizing for 125 W dissipation at T_C = 25°C.
t_SC	120 µs - Short-circuit withstand time under defined test conditions, supporting fault handling in inverter protection schemes.
I_L (L = 4.7 mH)	11.5 A @ T_C = 25°C - Self-clamped inductive switching current defines maximum safe energy absorption without external snubber.

Pinout & Package

IRGS14C40LTRLP uses the TO-263-3 (D²PAK) surface-mount package with isolated heatsink tab. Pin assignments are standardized per JEDEC MO-211AB: Pin 1 = Gate, Pin 2 = Collector (tab), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Receives gate drive signal; internal R1 (75 Ω) limits di/dt and suppresses oscillation during turn-on.
Pin 2 (Collector)	High-side power terminal	Connected to heatsink tab; carries full load current and must be electrically isolated from PCB ground plane.
Pin 3 (Emitter)	Power return / reference node	Serves as source of gate drive return path; internal R2 (10–30 kΩ) ensures gate discharge during 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 behavior.
Self-clamped avalanche capability	Rated for 11.5 A inductive current at 4.7 mH and 25°C, enabling snubberless operation in flyback and motor freewheeling.
Short-circuit ruggedness	Withstands 120 µs at V_CC = 16 V and L = 10 µH, supporting reliable overcurrent protection in variable-speed drives.
Wide operating temperature	Junction range –40°C to 175°C supports deployment in harsh environments including industrial enclosures and outdoor HVAC units.
Low V_CE(on) drift	1.55 V @ 14 A, 5 V_GE, 25°C rising to only 1.75 V at 150°C, minimizing thermal runaway risk in parallel configurations.

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(on) (1.8 V typ)	Requires external R_G tuning; lower current rating limits use in 20 A designs	Select when gate drive layout flexibility is prioritized over component count reduction.
IXGH14N40C3	400 V, 14 A, standard gate structure; no self-clamp rating; higher Q_g (35 nC)	Lacks avalanche ruggedness spec; needs external snubber for inductive loads	Choose where cost-per-watt is critical and system-level protection handles short-circuit events.

Compared with STGP14NC40KD and IXGH14N40C3, IRGS14C40LTRLP uniquely combines 20 A rating, integrated R1/R2, and validated 11.5 A self-clamped inductive current-enabling snubberless, space-constrained inverter designs with reduced gate drive complexity and improved thermal predictability.

FAQ

What is the maximum recommended gate resistor value when using IRGS14C40LTRLP?

The device integrates R1 = 75 Ω in series with the gate and R2 = 10–30 kΩ from gate to emitter. External gate resistors are not required for basic operation. If added, values exceeding 10 Ω may degrade switching speed and increase losses; Infineon recommends keeping external R_G ≤ 5 Ω to avoid compromising the built-in optimization.

Does IRGS14C40LTRLP require a negative gate voltage for reliable turn-off?

No. IRGS14C40LTRLP is specified for V_GE = 0 V turn-off and features an internal 10–30 kΩ pull-down resistor (R2) that ensures gate discharge. A negative gate voltage is not necessary, though it may be used in noise-prone environments to improve noise immunity-provided V_GE remains within the ±20 V absolute maximum rating.

Can IRGS14C40LTRLP be paralleled with other IGBTs for higher current capacity?

Yes, but with strict layout and gate drive matching. The device exhibits positive V_CE(on) temperature coefficient above 100°C, supporting current sharing. Successful paralleling requires matched gate drive impedance, symmetrical power loop inductance (<5 nH difference), and individual emitter resistors for current sensing-per Infineon Application Note AN2015-09.

What is the meaning of "self-clamped inductive switching" in the datasheet?

It refers to the device's ability to safely absorb inductive energy during turn-off without external snubbers by entering controlled avalanche breakdown. At L = 4.7 mH and T_C = 25°C, it sustains 11.5 A peak current while clamping V_CE to ≤430 V, verified per JEDEC JESD24-11 test conditions-enabling simpler, more reliable inverter designs.
