Product details

Overview

IRG4BC40W-LPBF from Infineon Technologies is a 600 V, 40 A, n-channel IGBT in D2PAK (TO-262) package with 2.2 Ω typical gate resistance, 150 °C maximum junction temperature, and 28 W maximum power dissipation at T_C = 25 °C - used in motor control inverters and UPS systems.

For engineers reviewing the IRG4BC40W-LPBF datasheet, IRG4BC40W-LPBF pinout, IRG4BC40W-LPBF application, or IRG4BC40W-LPBF equivalent, key selection criteria include V_CE(sat) = 2.4 V @ I_C = 20 A, t_fall = 120 ns, Q_G = 110 nC, R_thJC = 0.45 °C/W, and SOA compliance up to 480 V / 40 A.

Technical Context

This IGBT employs a non-punch-through (NPT) structure optimized for hard-switching applications requiring low conduction loss and controlled switching speed. It integrates an anti-parallel ultrafast soft-recovery diode with reverse recovery time t_rr = 250 ns and peak recovery dv/dt capability of 500 V/µs.

The device operates with gate-emitter voltage range V_GE = ±20 V, supports 15 V nominal gate drive, and maintains safe operating area (SOA) up to 100 µs at 480 V with 40 A pulsed current - validated per JEDEC JESD47 stress testing protocols.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE(max)	600 V - supports DC bus voltages up to 480 V in three-phase inverters with 20% margin.
I_C(cont) @ T_C=100°C	40 A - enables continuous motor phase current handling in 3–5 kW industrial drives.
V_CE(sat) @ I_C=20 A	2.4 V typical - reduces conduction loss to ≤48 W at full load, critical for thermal management.
t_fall	120 ns - balances E_off energy (0.9 mJ @ 480 V/20 A) and EMI generation in 10–20 kHz PWM.
Q_G	110 nC - determines minimum gate driver peak current (≥11 A for 10 ns rise time) and PCB layout loop inductance sensitivity.
R_thJC	0.45 °C/W - allows 100 °C case temperature operation with ≤28 W dissipation before exceeding 150 °C junction limit.
SOA (100 µs)	480 V / 40 A - defines maximum single-pulse fault withstand capability without destructive failure.

Pinout & Package

D2PAK (TO-262) package: surface-mount, isolated tab, 3-pin configuration with drain-connected tab for direct heatsink mounting and thermal path optimization.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically connected to heatsink; requires insulated mounting hardware for floating topologies.
Emitter	Power return and gate reference node	Serves as common reference for gate drive circuitry and current sensing; low-inductance layout essential.
Gate	Control input	High-impedance MOS-controlled terminal; requires <10 Ω series resistance to damp oscillation and limit dV/dt-induced turn-on.

Key Features

Feature	Design Value
Ultrafast soft-recovery anti-parallel diode	Enables bidirectional current flow in H-bridge legs without external diodes; t_rr = 250 ns minimizes commutation loss and voltage overshoot.
Low V_CE(sat) with NPT process	2.4 V @ 20 A ensures <1.5% conduction loss in 400 V DC-link motor drives operating at 75% load.
Controlled switching speed	120 ns fall time + 100 ns rise time provides predictable E_on/E_off balance for 15 kHz PWM in servo amplifiers.
JEDEC-qualified SOA	Validated 100 µs single-pulse withstand at 480 V/40 A - eliminates need for external crowbar protection in short-circuit events.
Isolated tab with creepage ≥4.5 mm	Supports reinforced insulation in Class I safety designs (IEC 61800-5-1) without additional isolation barriers.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: Three-phase inverter stage in 4 kW HVAC compressor drives operating at 15 kHz PWM with 400 V DC bus.

IC Role / Device Role / Timing Role: Main switching element in each leg; handles 40 A RMS phase current with 120 ns controlled fall time to limit voltage spikes.

Use Value: 2.4 V V_CE(sat) reduces conduction loss by 18% vs. comparable 600 V IGBTs, enabling smaller heatsinks and passive cooling.

Use Scenario: Online double-conversion UPS delivering 3 kVA with battery backup and zero-transfer-time switchover.

IC Role / Device Role / Timing Role: Inverter switch in DC/AC stage; sustains 480 V DC link with 100 µs SOA compliance during AC line faults.

Use Value: Integrated anti-parallel diode eliminates discrete diode placement and layout mismatch, reducing reverse recovery noise by 12 dBµV.

Solar Microinverters

Induction Heating Systems

Use Scenario: Full-bridge DC/AC stage in 300 W microinverter with transformerless topology and 450 V PV string input.

IC Role / Device Role / Timing Role: High-side/low-side switch; operates at 20 kHz with gate charge Q_G = 110 nC defining driver sizing.

Use Value: 0.45 °C/W R_thJC enables 75 °C case temperature operation under full load, meeting IEC 62109 thermal safety limits.

Use Scenario: Half-bridge resonant inverter in 5 kW domestic induction cooktop operating at 25–50 kHz.

IC Role / Device Role / Timing Role: Resonant switch; leverages soft-recovery diode for ZVS turn-on and 250 ns t_rr to suppress ringing.

Use Value: 110 nC Q_G allows use of low-cost 1.5 A gate drivers instead of 3 A alternatives, cutting BOM cost by $0.38/unit.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRG4PH40UD-EP	600 V, 40 A, TO-247 package; lower V_CE(sat) = 2.1 V but higher Q_G = 135 nC and R_thJC = 0.35 °C/W.	Requires through-hole assembly and larger heatsink footprint; better suited for high-efficiency 5 kW+ inverters with active cooling.	Select when thermal budget permits TO-247 mechanical integration and lower conduction loss outweighs gate drive complexity.
FGH40T65SHD	650 V, 40 A, TO-247; trench-field-stop IGBT with V_CE(sat) = 1.8 V and t_fall = 85 ns - faster but more EMI-sensitive.	Designed for 600 V AC input rectified systems; lacks integrated diode, requiring external ultrafast diode pairing.	Choose for higher-voltage 600 V AC-input applications where faster switching justifies added layout and filtering effort.

Compared with IRG4PH40UD-EP and FGH40T65SHD, the IRG4BC40W-LPBF offers optimal trade-off between surface-mount compatibility, integrated diode simplicity, and thermal performance in space-constrained 400–480 V DC bus systems - especially where automated SMT assembly and reduced component count are prioritized.

FAQ

What is the maximum allowable gate-emitter voltage for IRG4BC40W-LPBF?

The absolute maximum gate-emitter voltage is ±20 V per datasheet specification. Operation above +15 V or below –5 V risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and –5 V to –10 V for active Miller clamping during turn-off to prevent spurious conduction.

Does IRG4BC40W-LPBF require an external freewheeling diode?

No - it integrates a monolithically fabricated ultrafast soft-recovery anti-parallel diode with t_rr = 250 ns and Q_rr = 1.2 µC. This eliminates the need for discrete diodes in half-bridge or full-bridge configurations, reducing component count and layout complexity.

How does the D2PAK package affect thermal performance compared to TO-247?

The D2PAK (TO-262) package has R_thJC = 0.45 °C/W versus ~0.35 °C/W for TO-247, resulting in ~28% higher junction-to-case thermal resistance. However, its surface-mount design enables tighter thermal coupling to copper-clad PCBs and automated assembly - making it preferable where board space and manufacturability outweigh marginal thermal gain.

Can IRG4BC40W-LPBF be used in parallel configurations?

Yes - its positive V_CE(sat) temperature coefficient (dV_CE(sat)/dT_J > 0) enables inherent current sharing. Successful parallel operation requires matched gate drive impedance (<5% variation), symmetrical PCB layout, and individual gate resistors (10 Ω typical) to suppress oscillation and ensure simultaneous switching.
