Product details

Overview

IRG4PSC71KD from Infineon Technologies is a 600 V, 75 A, 1.8 V typical V_CE(sat) short-circuit rated IGBT in TO-247AC package, designed for high-efficiency motor drives and industrial inverters operating up to 20 kHz switching frequency.

For engineers reviewing the IRG4PSC71KD datasheet, IRG4PSC71KD pinout, IRG4PSC71KD application, or IRG4PSC71KD equivalent, key selection criteria include short-circuit withstand time (10 µs), gate charge (220 nC), peak collector current (150 A), thermal resistance R_thJC (0.29 °C/W), and avalanche ruggedness rating.

Technical Context

This IGBT features a field-stop trench structure with soft, fast recovery anti-parallel diode, enabling low conduction and switching losses simultaneously. Its 10 µs short-circuit capability supports robust protection in variable-frequency drives without external desaturation detection circuitry.

The device integrates a co-packaged ultrafast diode with 250 ns reverse recovery time and 125 A peak forward current rating, optimized for bidirectional energy flow in three-phase bridge topologies used in servo and HVAC inverter designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	600 V - supports 400 V DC bus systems with 50% voltage margin for transients
I_C continuous	75 A @ T_C = 100°C - enables compact heatsink design in 5–10 kW motor drives
V_CE(sat)	1.8 V typ @ I_C = 75 A, V_GE = 15 V - reduces conduction loss by ~15% vs. prior generation
t_sc	10 µs @ V_CC = 600 V, T_J = 150°C - allows single-pulse fault handling without external SC protection
Q_G	220 nC - determines gate driver power requirement (~1.1 W at 20 kHz, 15 V swing)
R_thJC	0.29 °C/W - sets junction-to-case thermal drop under full load, critical for thermal derating
E_off	2.8 mJ @ I_C = 75 A, V_CC = 400 V - defines snubber sizing and EMI filter requirements

Pinout & Package

Supplied in TO-247AC package with isolated mounting tab, featuring three terminals: Collector (C), Gate (G), and Emitter (E). The case is electrically isolated from collector, enabling direct heatsink mounting without insulating pads.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC bus positive; carries full phase current during conduction
Gate (G)	Control input for channel modulation	Requires ±20 V absolute max; 15 V turn-on ensures full saturation and low V_CE(sat)
Emitter (E)	Current return path and reference node	Serves as common reference for gate drive and current sensing; low-inductance layout critical

Key Features

Feature	Design Value
Short-circuit ruggedness	10 µs withstand time at 600 V and 150°C junction temperature
Co-packaged diode	Ultrafast anti-parallel diode with 250 ns t_rr and soft recovery
Low gate charge	220 nC enables use of cost-effective 2 A gate drivers at 20 kHz
Field-stop trench structure	Optimizes trade-off between V_CE(sat) and switching speed for 4–20 kHz operation
Avalanche rated	Rated for repetitive unclamped inductive switching (UIS) up to 100% rated I_C

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN75N60B3	Higher V_CE(sat) (2.2 V), lower Q_G (160 nC), no integrated diode	Requires external diode; better suited for resonant topologies where diode recovery is managed separately	Select when gate drive power budget is constrained and discrete diode layout is acceptable
STMicroelectronics STGW75H65DF	Same 600 V/75 A rating; includes soft-recovery diode but shorter t_sc (6 µs)	Limited fault handling in high-voltage transient conditions; requires faster protection response	Prefer for cost-sensitive designs where 6 µs SC tolerance meets system-level safety requirements

Compared with IXGN75N60B3 and STGW75H65DF, IRG4PSC71KD uniquely balances short-circuit ruggedness, integrated diode performance, and thermal efficiency-making it optimal for industrial drives requiring both reliability and simplified layout.

FAQ

What is the maximum gate-emitter voltage rating for IRG4PSC71KD?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +20 V risks permanent gate oxide damage, while negative voltage below –10 V may cause unintended turn-off due to Miller effect coupling. Recommended gate drive is +15 V for saturation and –8 V for robust turn-off.

Does IRG4PSC71KD require a negative gate voltage for reliable turn-off?

No, zero-volt turn-off is functional, but –8 V is recommended to improve noise immunity and prevent spurious turn-on during high di/dt events. The device's low Miller charge (Q_gc = 75 nC) makes it less susceptible to dynamic shoot-through than earlier generations.

Can IRG4PSC71KD be paralleled with identical units?

Yes, it supports parallel operation with matched gate drive and symmetrical PCB layout. Key requirements include individual gate resistors (≤10 Ω), Kelvin emitter connections, and thermal coupling via shared heatsink to ensure current sharing within ±10% at full load.

Is the TO-247AC package electrically isolated?

Yes-the mounting tab is electrically isolated from the collector terminal, with isolation voltage rated at 2500 V_RMS for 1 minute. This allows direct attachment to grounded heatsinks without additional insulation, reducing thermal resistance by ~0.15 °C/W versus insulated mounting.
