Product details

Overview

IRG4CC40KB from Infineon Technologies is a 600V, 40A, 1.8V gate threshold N-channel IGBT in TO-247AC package, designed for hard-switched and resonant-mode power conversion in industrial motor drives and UPS systems. It features 2.5µs turn-off time, 1.7V saturation voltage at 40A, and 150°C maximum junction temperature.

For engineers reviewing the IRG4CC40KB datasheet, IRG4CC40KB pinout, IRG4CC40KB application, or IRG4CC40KB equivalent, key selection criteria include V_CE(sat) stability under 100°C case temperature, short-circuit withstand time of 10µs, and gate charge of 120nC - all critical for high-efficiency 3-phase inverter stage design.

Technical Context

This IGBT employs a trench-gate field-stop structure enabling low conduction loss while maintaining robust short-circuit capability. Its gate oxide thickness and emitter layout are optimized for 150°C continuous operation with controlled tail current decay.

The device integrates an anti-parallel ultrafast soft-recovery diode with 75ns reverse recovery time and 120A peak forward surge rating, supporting bidirectional energy flow in regenerative braking circuits without external freewheeling diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	600V - supports 400V AC input rectified bus with 50% safety margin for transient overvoltage in industrial mains-fed inverters.
I_C cont @ T_C=100°C	40A - enables 5.5kW output in 3-phase 400V motor drive with forced-air cooling at 100°C heatsink temperature.
V_CE(sat) @ I_C=40A	1.7V - contributes ≤68W conduction loss per device, reducing thermal load in compact inverter modules.
t_sc	10µs - allows reliable desaturation protection response in microsecond-scale fault detection circuits.
Q_g	120nC - determines gate driver peak current requirement (≥2A) for <100ns switching transitions.
E_off @ T_j=125°C	1.2mJ - defines snubber sizing and switching loss budget in 16kHz PWM motor control stages.

Pinout & Package

TO-247AC package: 3-pin through-hole outline with isolated tab, creepage ≥4.5mm, thermal resistance R_th(j-c) = 0.45°C/W.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to DC bus positive; rated for 600V blocking and 120A non-repetitive surge.
Gate (G)	Control input	Requires ±20V absolute max; 120nC total charge mandates low-impedance gate driver path to minimize switching losses.
Emitter (E)	Power return and reference node	Serves as common source for gate drive return and current sensing; must be low-inductance layout to avoid false triggering.

Key Features

Feature	Design Value
Trench Field-Stop IGBT structure	Enables simultaneous optimization of V_CE(sat) and E_off, achieving 1.7V/1.2mJ trade-off at 125°C junction.
Integrated ultrafast diode	75ns t_rr with soft recovery reduces EMI and voltage overshoot during commutation in PFC and inverter legs.
150°C maximum junction temperature	Supports derated operation up to 100°C case temperature without thermal runaway, simplifying heatsink sizing.
10µs short-circuit withstand time	Allows use with standard desaturation detection circuits (e.g., Infineon 2ED020I12-F2) without external crowbar components.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: 3-phase 5.5kW inverter stage for HVAC compressors operating at 16kHz PWM with 400V DC bus.

IC Role / Device Role / Timing Role: Main switching device in each leg of the inverter bridge; handles bidirectional current via integrated diode during regeneration.

Use Scenario: Online double-conversion UPS with 10ms transfer time and 94% efficiency at full load.

IC Role / Device Role / Timing Role: Inverter-stage switch converting battery DC to clean 230V AC; operates in hard-switched mode with active clamp snubbing.

Use Value: 10µs short-circuit rating enables deterministic fault shutdown before transformer saturation, preserving isolation integrity during grid failure events.

Solar String Inverters

Induction Heating Systems

Use Scenario: 3.3kW string inverter DC-AC stage with unipolar modulation and 25kHz switching frequency.

IC Role / Device Role / Timing Role: High-side switch in H-bridge topology; conducts 40A RMS with 120A surge during MPPT transients.

Use Value: 75ns diode t_rr limits reverse recovery dv/dt to <50V/ns, eliminating need for RC snubbers on DC-link capacitors.

IC Role / Device Role / Timing Role: Half-bridge switch controlling series-resonant LC tank; subjected to zero-voltage switching transitions.

Use Value: Low Q_g (120nC) enables gate drive power reduction to <1.5W per device, improving driver IC thermal margin at 100% duty cycle.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN40N60B3	Higher V_CE(sat) (1.95V), lower Q_g (95nC), no integrated diode	Requires external ultrafast diode; better suited for ZVS topologies where diode recovery is managed separately	Select when gate drive power is constrained and discrete diode layout is acceptable
STMicroelectronics STGW40H65DFB	Same V_CE/I_C rating but higher E_off (1.8mJ), integrated diode with 100ns t_rr	Higher switching loss limits usable frequency to ≤12kHz in hard-switched inverters	Select when cost sensitivity outweighs 15% efficiency penalty in low-frequency industrial drives

Compared with IXGN40N60B3 and STGW40H65DFB, IRG4CC40KB delivers the lowest combined conduction–switching loss at 16kHz in hard-switched 3-phase inverters, making it optimal for space- and efficiency-critical motor drive designs where integrated diode simplifies layout.

FAQ

What is the maximum gate-emitter voltage rating for IRG4CC40KB?

The absolute maximum V_GE is ±20V. Operation beyond ±15V risks irreversible gate oxide damage. Recommended gate drive is +15V for turn-on and –5V to –8V for turn-off to ensure robust noise immunity and prevent Miller-induced false turn-on during high dv/dt commutation events.

Does IRG4CC40KB require an external freewheeling diode?

No. IRG4CC40KB integrates an ultrafast soft-recovery diode rated for 40A continuous and 120A non-repetitive surge. Its 75ns reverse recovery time and soft recovery characteristic eliminate the need for external diodes in standard inverter leg configurations, reducing PCB area and component count.

What is the thermal resistance from junction to case for IRG4CC40KB?

R_th(j-c) is 0.45°C/W, measured under standard mounting conditions with 0.5mm silicone grease and 25N·cm screw torque. This value assumes full tab contact to a flat, oxidized-aluminum heatsink surface; actual thermal performance degrades by ~15% if mounting pressure falls below 20N·cm.

Can IRG4CC40KB be used in parallel configurations?

Yes, but only with matched devices and symmetrical gate drive layout. The positive V_CE(sat) temperature coefficient (0.3mV/°C) enables current sharing up to 3 devices in parallel. Each gate must have individual 5Ω series resistance and local 100nF decoupling to suppress oscillation and ensure simultaneous turn-on.
