Product details

Overview

IRGBC40U from Infineon Technologies (formerly International Rectifier) is a 600 V, 40 A ultrafast insulated gate bipolar transistor in TO-220AB package, optimized for high-frequency switching (>5 kHz) with 2.2–3.0 V V_CE(sat) at 20–40 A and total switching loss of 0.75–1.4 mJ across 25–150 °C junction temperature. It delivers low tail losses and robust clamped inductive load capability (160 A I_LM) for motor drive inverters.

For engineers reviewing the IRGBC40U datasheet, IRGBC40U pinout, IRGBC40U application, or IRGBC40U equivalent, key selection criteria include V_CE(sat) vs. temperature, E_off/E_on balance at 480 V bus, gate charge (51–67 nC), thermal resistance (R_θJC = 0.77 °C/W), and SOA compliance under clamped inductive loads.

Technical Context

The IRGBC40U integrates a field-stop IGBT structure with optimized carrier lifetime control to minimize tail current while maintaining low conduction loss. Its gate threshold voltage (3.0–5.5 V) and negative temperature coefficient of V_GE(th) (−13 mV/°C) enable stable parallel operation across temperature.

Switching behavior is characterized by 25 ns t_d(on), 21–23 ns t_r, 96–174 ns t_d(off), and 43–140 ns t_f under 10 Ω gate drive, with C_ies = 1500 pF and C_res = 17 pF enabling predictable Miller-effect control in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - supports 400 V AC input rectified bus with 20% margin for surge
I_C @ T_C = 25°C	40 A - continuous conduction capability at heatsink baseplate ≤25°C
V_CE(sat)	2.2–3.0 V @ 20–40 A - determines conduction loss and thermal rise in inverter legs
E_ts	0.75–1.4 mJ @ 480 V, 20 A - defines energy dissipation per switching cycle at 5–20 kHz
R_θJC	0.77 °C/W - enables direct thermal interface to heatsink without insulator penalty
Q_g	51–67 nC - sets gate driver peak current requirement (≥3.4 A for 15 ns rise)
I_LM	160 A - sustains short-circuit events in motor phase-legs with active protection

Pinout & Package

TO-220AB package with isolated mounting tab (electrically connected to collector), standard 3-pin vertical lead frame, and 10 lbf·in (1.1 N·m) screw torque rating. Case-to-sink thermal resistance is 0.50 °C/W with flat greased surface.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Internally bonded to metal tab; requires electrical isolation from heatsink unless system ground-referenced
Gate (G)	Control input	High-impedance MOS-like input requiring <51–67 nC charge for full turn-on; sensitive to dV/dt coupling
Emitter (E)	Power return reference	Low-inductance path (7.5 nH internal) critical for minimizing shoot-through risk in half-bridge layout

Key Features

Feature	Design Value
Tail-loss–optimized switching	Reduces E_off contribution by >30% vs. standard IGBTs, enabling higher frequency operation without excessive loss trade-off
Clamped inductive load rating	160 A I_LM at T_J = 150°C ensures reliable short-circuit withstand in motor drives with active desat detection
Negative V_GE(th) tempco	−13 mV/°C improves current sharing stability when paralleling multiple devices across wide temperature gradients
Low C_res/C_ies ratio	17 pF / 1500 pF = 0.011 - minimizes Miller-induced false turn-on during high dV/dt commutation

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGP40H60DF	V_CE(sat) = 2.4 V @ 20 A; Q_g = 62 nC; R_θJC = 0.85 °C/W	Higher conduction loss, slightly slower turn-off (t_d(off) = 120 ns typ.)	Better suited for lower-frequency (<8 kHz), higher-current designs where thermal margin exceeds 10 °C
IXYS IXGH40N60B3	V_CE(sat) = 2.6 V @ 20 A; E_off = 0.52 mJ; C_res = 22 pF	Higher switching loss and Miller capacitance; no clamped inductive rating published	Preferred where ruggedness is secondary to cost in non-critical industrial controls

Compared with STGP40H60DF and IXGH40N60B3, the IRGBC40U offers superior high-frequency efficiency due to lower E_ts and tighter V_CE(sat) tolerance, making it optimal for compact, thermally constrained inverters requiring >12 kHz operation and fast fault response.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off at 150 °C junction temperature?

A 10 Ω gate resistor is validated in the datasheet for t_d(off) ≤174 ns and E_off ≤0.41 mJ at T_J = 150 °C. Increasing beyond 12 Ω risks exceeding safe SOA limits during clamped inductive switching; use active Miller clamp or negative turn-off bias if higher impedance is required for EMI control.

Does the IRGBC40U have an integrated anti-parallel diode?

No. The IRGBC40U is a discrete IGBT without monolithically integrated freewheeling diode. External ultrafast diodes (e.g., IDP40E65D2) must be used in complementary pairs for inductive load commutation and reverse recovery management.

Can the IRGBC40U be paralleled for higher current capacity?

Yes-its negative V_GE(th) temperature coefficient (−13 mV/°C) and matched transfer characteristics support stable current sharing. Use matched gate resistors (±1%), symmetrical PCB layout, and common-source emitter inductance <5 nH to ensure balanced dynamic current distribution.

What is the meaning of "switching-loss rating includes all tail losses" in the datasheet?

This indicates that the published E_on and E_off values (0.34 mJ and 0.41 mJ) fully account for minority-carrier recombination tail current, not just the initial rapid fall/rise. No additional tail-loss derating is needed in thermal calculations for 5–20 kHz operation.
