Product details

Overview

IRG7PH42UDPBF from Infineon Technologies is a trench-gate field-stop IGBT rated for 1200 V collector-emitter voltage, 85 A nominal collector current at T_c = 25 °C, and 42 A at T_c = 100 °C, optimized for high-efficiency industrial motor drives and UPS inverters.

For engineers reviewing the IRG7PH42UDPBF datasheet, IRG7PH42UDPBF pinout, IRG7PH42UDPBF application, or IRG7PH42UDPBF equivalent, key selection criteria include V_CE(sat) @ I_C = 42 A (2.1 V max), switching energy E_ON/E_OFF, short-circuit withstand time (6 µs), and TO-247AC package thermal resistance R_thJC = 0.33 K/W.

Technical Context

This IGBT employs Infineon's TRENCHSTOP™ 5 technology with field-stop layer and optimized carrier lifetime control to achieve low conduction and switching losses simultaneously. It features a positive temperature coefficient for V_CE(sat), enabling stable paralleling without current-sharing resistors.

The device integrates an ultrafast soft-recovery anti-parallel diode with reverse recovery charge Q_rr = 3.9 µC and peak reverse recovery current I_RRM = 72 A at T_j = 150 °C, reducing voltage overshoot during turn-off commutation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 800 V in three-phase 600 V AC input systems with safety margin.
I_C @ T_c = 100 °C	42 A - continuous collector current rating under real-world heatsink-limited thermal conditions.
V_CE(sat) @ I_C = 42 A	2.1 V (max) - low saturation voltage reduces conduction loss and heatsink sizing requirements.
E_ON + E_OFF @ I_C = 42 A	3.2 mJ - total switching energy per cycle at rated current, enabling >16 kHz operation in servo drives.
t_sc	6 µs - guaranteed short-circuit withstand time at V_CE = 600 V, T_j = 150 °C, supporting robust protection design.
R_thJC	0.33 K/W - junction-to-case thermal resistance enables efficient heat transfer to external heatsink.

Pinout & Package

IRG7PH42UDPBF is housed in a TO-247AC package with isolated tab, featuring three terminals: Collector (C), Gate (G), and Emitter (E). The metal tab is electrically connected to the collector, requiring insulating mounting hardware in most applications.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to high-side DC bus or motor phase; carries full load current and must be routed with low-inductance layout.
Gate (G)	Control input	Receives PWM signal; requires gate driver capable of ±20 V rating and ≥2 A peak drive current for fast switching.
Emitter (E)	Power return and reference node	Serves as common reference for gate drive and current sensing; layout must minimize stray inductance to prevent voltage spikes.

Key Features

Feature	Design Value
TrenchStop™ 5 silicon process	Enables simultaneous optimization of V_CE(sat) and switching speed without trade-off degradation across temperature range.
Integrated ultrafast soft-recovery diode	Reduces turn-off voltage overshoot by limiting di/dt during commutation, eliminating need for external snubbers in many designs.
Positive V_CE(sat) temperature coefficient	Ensures inherent current balancing when multiple devices are paralleled, simplifying thermal management in high-power modules.
Short-circuit ruggedness (6 µs)	Allows implementation of simple overcurrent protection using fixed-time blanking, reducing gate driver complexity and cost.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: Three-phase inverter stage in 15–30 kW variable-frequency drives for HVAC compressors and pumps.

IC Role / Device Role / Timing Role: High-side switching element in six-pack inverter topology, operating at 8–16 kHz PWM frequency.

Use Value: Low V_CE(sat) and balanced E_ON/E_OFF reduce system-level conduction and switching losses, improving efficiency to >97.5% at full load.

Use Scenario: Inverter output stage in online double-conversion UPS systems delivering clean 230 V AC to critical IT loads.

IC Role / Device Role / Timing Role: Main power switch in H-bridge output stage, handling bidirectional energy flow during battery backup mode.

Use Value: 6 µs short-circuit rating supports fast fault response (<10 µs detection + blanking), ensuring zero output interruption during grid transients.

Solar String Inverters

Induction Heating Systems

Use Scenario: DC–AC conversion stage in 10–25 kW string inverters interfacing PV arrays to single-phase or split-phase grids.

IC Role / Device Role / Timing Role: High-voltage bridge leg switch operating with unipolar modulation and active neutral-point clamping.

Use Value: 1200 V blocking voltage accommodates 1000 V DC input with 20% margin, enabling higher string voltages and reduced BOM cost per kW.

Use Scenario: Half-bridge resonant inverter in 15–40 kW induction cooktops and industrial heating generators.

IC Role / Device Role / Timing Role: Primary switching device in ZVS-resonant topology, switching at 20–50 kHz with soft turn-on/turn-off.

Use Value: Integrated soft-recovery diode eliminates external freewheeling diode, reducing component count and PCB area while maintaining low EMI.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN75N120B3	Higher V_CE(sat) (2.4 V max @ 42 A), lower E_OFF, TO-247-3L package with non-isolated tab.	Requires insulated mounting hardware only if collector is not at chassis ground; less suitable for floating-source topologies.	Prefer where lower switching loss dominates over conduction loss, and thermal interface allows direct tab mounting.
STMicroelectronics STGP40H120DF	Lower I_C rating (32 A @ T_c = 100 °C), higher R_thJC (0.45 K/W), same 1200 V rating.	Better suited for space-constrained designs with forced-air cooling rather than liquid-cooled high-power systems.	Select when board-level thermal budget limits maximum junction temperature to ≤145 °C and peak current demand is ≤32 A.

Compared with IXGN75N120B3 and STGP40H120DF, IRG7PH42UDPBF delivers the best balance of conduction efficiency, short-circuit ruggedness, and integrated diode performance for thermally demanding industrial inverters requiring >40 A continuous current capability.

FAQ

What gate resistor value is recommended for IRG7PH42UDPBF in a 16 kHz motor drive application?

A gate resistor of 10 Ω (non-inductive) is recommended to limit peak gate current to ~2 A while achieving ~250 ns turn-on and ~350 ns turn-off delays. This balances switching loss reduction against EMI control and gate driver stress. Layout parasitics must be minimized to avoid oscillation, especially on the gate loop.

Does IRG7PH42UDPBF require negative gate voltage for reliable turn-off?

No. IRG7PH42UDPBF is fully specified for 0 V to +15 V gate drive with no requirement for negative bias. However, applying –5 V to –8 V during off-state improves noise immunity and prevents spurious turn-on in high-dV/dt environments such as multi-level inverters or high-frequency SiC co-designs.

Can IRG7PH42UDPBF be paralleled without emitter resistors?

Yes-its positive V_CE(sat) temperature coefficient ensures natural current sharing across parallel devices. Thermal coupling between dies must be uniform (e.g., shared heatsink with identical mounting pressure), and gate drive paths must be symmetrical to avoid dynamic imbalance. No emitter degeneration resistors are needed.

What is the maximum allowable case temperature for continuous operation?

The maximum continuous case temperature is 100 °C, corresponding to 42 A rated collector current. Operation above this requires derating per the datasheet's I_C vs. T_c curve. At T_c = 80 °C, maximum continuous I_C rises to 58 A; at T_c = 110 °C, it drops to 35 A.
