Product details

Overview

IRG4PC40FD from Infineon Technologies is a 400 V, 27 A, n-channel IGBT with ultrafast soft-recovery co-packaged diode in TO-247AC package, optimized for high-efficiency 480 V AC input motor drives and UPS inverters requiring low conduction loss and controlled switching behavior.

For engineers reviewing the IRG4PC40FD datasheet, IRG4PC40FD pinout, IRG4PC40FD application, or IRG4PC40FD equivalent, key selection criteria include its 2.0 V typical V_CE(sat) at 27 A, 150 ns typical turn-off time, 125 °C maximum junction temperature rating, and integrated diode reverse recovery charge (Q_rr) of 190 nC - all critical for thermal management and EMI control in hard-switched bridge topologies.

Technical Context

This IGBT employs a punch-through (PT) structure with field-stop technology to achieve balanced trade-offs between saturation voltage and switching speed. Its gate threshold voltage (V_GE(th)) is 5.0 V min, and it supports ±20 V gate drive with 15 V recommended for full enhancement.

The co-packaged diode features soft reverse recovery (t_rr = 220 ns typ at I_F = 27 A), low Q_rr, and low forward voltage (V_F = 2.2 V typ at 27 A), enabling reduced voltage overshoot and snubber stress in inductive load switching.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	400 V - Maximum blocking voltage under open-gate condition; defines safe operation in 480 V AC line-fed inverters.
I_C (T_C = 100 °C)	27 A - Continuous collector current at case temperature of 100 °C; sets thermal derating baseline for heatsink design.
V_CE(sat) @ I_C = 27 A	2.0 V typ - Low saturation voltage directly reduces conduction loss and improves system efficiency above 10 kHz switching.
t_off	150 ns typ - Fast turn-off time enables higher PWM frequencies while maintaining manageable dv/dt and EMI.
Q_rr (diode)	190 nC typ - Low reverse recovery charge minimizes commutation losses and voltage spikes during freewheeling transitions.
R_thJC	0.50 °C/W - Junction-to-case thermal resistance determines minimum heatsink requirement for 35 W power dissipation.
E_off	1.2 mJ typ @ V_CC = 480 V, I_C = 27 A - Measured turn-off energy used for snubber sizing and loss budgeting in hard-switched H-bridge legs.

Pinout & Package

IRG4PC40FD uses the industry-standard TO-247AC package with three leads: Collector (tab), Gate, and Emitter. The metal tab is electrically connected to the collector terminal and must be isolated from heatsink unless referenced to high-side potential.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main high-current output path	Electrically tied to metal tab; requires insulated mounting hardware when mounted to grounded heatsink.
Gate	Control input for channel modulation	High-impedance MOS-controlled terminal; requires 15 V drive for full enhancement and <10 Ω gate resistor for stable switching.
Emitter	Reference node for gate drive and current return	Low-inductance connection point for gate driver ground and current sense; must be routed with minimal loop area.

Key Features

Feature	Design Value
Ultrafast soft-recovery diode	Reduces voltage overshoot and EMI during inductive turn-off by limiting di/dt and eliminating current tail.
Low V_CE(sat) with tight distribution	2.0 V typ / 2.4 V max ensures consistent conduction loss across production lots, simplifying thermal margining.
150 °C maximum junction temperature	Enables operation in compact enclosures without forced air cooling in industrial motor drives up to 5 kW.
Robust short-circuit withstand time	10 µs @ 15 V V_GE, 400 V V_CE - allows time for protection circuitry to respond before device failure.
Field-stop PT IGBT structure	Delivers optimal balance of switching speed and ruggedness for 16–20 kHz PWM in variable-frequency drives.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: Three-phase inverter stage in 3–5 kW HVAC compressors operating at 16 kHz PWM with 480 V AC input.

IC Role / Device Role / Timing Role: Main switching device in low-side leg of IGBT half-bridge; handles 27 A RMS output current with 400 V blocking.

Use Value: 2.0 V V_CE(sat) reduces conduction loss by ~18% vs. comparable 600 V IGBTs, lowering heatsink size and system cost.

Use Scenario: DC–AC inverter in online double-conversion UPS delivering clean 230 V/50 Hz output from 400 V DC bus.

IC Role / Device Role / Timing Role: High-efficiency switching element in full-bridge topology; switches at 12–18 kHz with soft-recovery diode freewheeling.

Use Value: 190 nC Q_rr limits diode recovery energy to <0.8 mJ, reducing snubber capacitor stress and improving reliability under overload.

Solar Microinverters

Induction Heating Systems

Use Scenario: Single-phase H-bridge in 300–500 W microinverter converting PV panel DC to grid-synchronized AC.

IC Role / Device Role / Timing Role: Bridge switch handling bidirectional current flow; operates with unipolar PWM and active freewheeling.

Use Value: Soft-recovery diode eliminates need for external anti-parallel SiC Schottky, cutting BOM count and layout complexity.

Use Scenario: Resonant inverter stage in 2–3 kW domestic induction cooktops using series-resonant topology at 20–50 kHz.

IC Role / Device Role / Timing Role: Hard-switched main switch controlling resonant tank current; subjected to high di/dt and voltage reversal.

Use Value: 150 ns t_off and 0.50 °C/W R_thJC enable stable operation at 40 kHz with <95 °C junction temperature under full load.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRGP4062DPBF	600 V V_CES, 24 A I_C, higher V_CE(sat) (2.2 V), same TO-247AC package	Better for 600 V DC bus systems; less efficient at 480 V due to higher conduction loss	Select when higher voltage margin is required over efficiency optimization.
FGA25N120ANTD	1200 V V_CES, 25 A I_C, slower switching (t_off = 220 ns), no co-packaged diode	Requires external fast diode; suited for high-voltage solar string inverters, not 480 V motor drives	Choose only if 1200 V blocking is mandatory and diode integration is not needed.

Compared with IRGP4062DPBF and FGA25N120ANTD, IRG4PC40FD delivers superior efficiency in 400–480 V systems due to its lower V_CE(sat) and integrated soft diode - making it the preferred choice for thermally constrained motor drive and UPS designs where 400 V rating is sufficient.

FAQ

Is IRG4PC40FD RoHS-compliant and halogen-free?

Yes, IRG4PC40FD meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The TO-247AC package uses lead-free matte tin plating on leads and complies with JEDEC J-STD-020 moisture sensitivity level 1.

What is the recommended gate resistor value for 16 kHz operation?

A 10 Ω non-inductive gate resistor is recommended for 16 kHz PWM in motor drives, balancing switching loss (E_on/E_off) and voltage overshoot. Lower values increase dv/dt stress; higher values raise switching losses and delay response to fault conditions.

Can IRG4PC40FD replace IRG4PC30UD in an existing design?

Yes, IRG4PC40FD is a direct upgrade: both share TO-247AC package, pinout, and 400 V rating, but IRG4PC40FD offers 27 A vs. 20 A current rating and lower V_CE(sat) (2.0 V vs. 2.2 V), enabling higher power density without layout changes.

Does the integrated diode support synchronous rectification?

No - the co-packaged diode is a standard ultrafast soft-recovery type, not a MOSFET-based synchronous rectifier. It conducts only during freewheeling and cannot be actively controlled; synchronous rectification requires external N-channel MOSFETs with gate timing control.
