Product details

Overview

IRG7PH46UDPBF from Infineon Technologies is a 1200 V, 40 A, 390 W trench gate field-stop IGBT in TO-247AC package, designed for high-voltage switching in industrial motor drives and UPS systems. It features low saturation voltage (V_CE(sat) = 2.1 V @ I_C = 40 A, T_j = 150 °C), fast turn-off time (t_f = 180 ns), and positive temperature coefficient for parallel operation.

For engineers reviewing the IRG7PH46UDPBF datasheet, IRG7PH46UDPBF pinout, IRG7PH46UDPBF application, or IRG7PH46UDPBF equivalent, key selection criteria include its 1200 V blocking capability, 40 A continuous collector current rating, thermal performance under forced-air cooling, and gate charge (Q_G = 120 nC) for driver sizing.

Technical Context

This IGBT employs Infineon's TrenchStop™ 7 technology with field-stop layer optimization to achieve balanced conduction and switching losses. Its gate threshold voltage (V_GE(th) = 5.5 V) ensures robust noise immunity, and the short-circuit withstand time (t_SC = 10 µs @ 15 V V_GE, T_j = 150 °C) supports protection circuit design in high-reliability inverters.

The device integrates an anti-parallel ultrafast soft-recovery diode with reverse recovery charge (Q_rr = 1.9 µC) and peak reverse recovery current (I_RRM = 45 A), enabling efficient freewheeling in bridge-leg configurations without external diode addition.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - maximum blocking voltage before avalanche breakdown; enables use in 690 V AC three-phase systems with 2× DC bus margin.
I_C (cont)	40 A @ T_c = 80 °C - continuous collector current rating at case temperature; defines heatsink sizing for steady-state operation.
V_CE(sat)	2.1 V @ I_C = 40 A, V_GE = 15 V, T_j = 150 °C - low on-state loss directly reduces conduction heating in motor drive output stages.
E_off	2.3 mJ @ I_C = 40 A, V_CE = 600 V, R_G = 22 Ω, T_j = 150 °C - quantifies energy dissipated during turn-off; critical for snubber and thermal design.
Q_G	120 nC - total gate charge; determines required peak gate driver current (e.g., >5.4 A for 22 ns rise time).
t_f	180 ns @ I_C = 40 A, V_CE = 600 V, R_G = 22 Ω - fast fall time enables higher PWM frequencies up to 20 kHz with controlled EMI.

Pinout & Package

Package: TO-247AC - industry-standard 3-pin through-hole power package with isolated tab, rated for 390 W dissipation at T_c = 80 °C and compatible with standard mounting hardware and insulating washers.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Connected to DC+ bus in half-bridge; carries full load current and must be routed with low-inductance layout.
Gate (G)	Control input for MOS-controlled IGBT channel	Requires low-impedance gate driver path; sensitive to ringing; needs 15 V ±10 % bias for reliable turn-on/turn-off.
Emitter (E)	Power return and reference node	Serves as common emitter for gate drive reference; must be low-inductance connection to minimize V_GE disturbance during switching.

Key Features

Feature	Design Value
TrenchStop™ 7 silicon technology	Enables simultaneous reduction of V_CE(sat) and E_off versus prior generations, improving efficiency in 10–20 kHz motor control.
Integrated ultrafast diode	Eliminates need for discrete antiparallel diode; soft recovery (t_rr = 120 ns) reduces voltage overshoot and EMI in inductive loads.
Positive V_CE(sat) temperature coefficient	Ensures inherent current sharing when paralleling multiple devices, simplifying thermal management in high-power modules.
10 µs short-circuit ruggedness	Supports implementation of desaturation detection circuits without external current-sense resistors in compact inverter designs.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies (UPS)

Use Scenario: Three-phase inverter stage in 30–50 kVA variable-frequency drives for HVAC compressors and pumps.

IC Role / Device Role / Timing Role: High-side switching element in six-pack IGBT module configuration; switched at 8–16 kHz with dead-time control.

Use Value: Low V_CE(sat) reduces conduction loss by ~15 % vs. comparable 1200 V IGBTs, lowering heatsink mass and fan power.

Use Scenario: Online double-conversion UPS output inverter delivering clean 230 V / 50 Hz sine wave to critical IT loads.

IC Role / Device Role / Timing Role: Output stage switch handling bidirectional energy flow during battery backup mode; operated with sinusoidal PWM.

Use Value: Integrated diode with low Q_rr minimizes reverse recovery loss during zero-crossing commutation, improving system efficiency by 0.8 % at full load.

Solar String Inverters

Induction Heating Systems

Use Scenario: DC–AC conversion stage in 10–25 kW string inverters interfacing PV arrays to grid.

IC Role / Device Role / Timing Role: Main switching device in H-bridge topology; modulated at 16–20 kHz to suppress audible noise and reduce filter size.

Use Value: Fast t_f and low E_off enable stable operation at 20 kHz while maintaining junction temperature <140 °C under natural convection.

Use Scenario: Resonant half-bridge in 15–30 kW induction cooktops and industrial heating generators.

IC Role / Device Role / Timing Role: Hard-switched resonant switch operating near zero-voltage switching (ZVS) boundary; requires precise timing control.

Use Value: Tight V_GE(th) distribution (±0.5 V) ensures consistent turn-on delay across units, critical for phase-matched bridge operation.

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 IXGN40N120B3	Higher V_CE(sat) (2.4 V), lower Q_G (95 nC), no integrated diode	Requires external ultrafast diode; better suited for ZVS-resonant topologies where gate drive loss dominates	Select if gate driver power budget is constrained and external diode integration is acceptable.
STMicroelectronics STGW40H120F2	Same V_CES/I_C, but slower t_f (280 ns), higher E_off (3.1 mJ)	Lower switching frequency limit (~12 kHz); preferred in cost-sensitive industrial drives with relaxed EMI requirements	Select when thermal margin allows larger heatsink and system EMI filtering is already optimized.

Compared with IXGN40N120B3 and STGW40H120F2, IRG7PH46UDPBF delivers superior conduction efficiency and integrated diode convenience at the expense of slightly higher gate drive demand-making it optimal for space-constrained, forced-air-cooled motor drives requiring ≤20 kHz operation.

FAQ

What is the maximum recommended gate-emitter voltage for IRG7PH46UDPBF?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +15 V increases risk of gate oxide degradation over time, while below +12 V may cause incomplete turn-on and elevated V_CE(sat). Infineon specifies +15 V for nominal turn-on and −5 V to −8 V for active Miller clamping during turn-off to prevent false triggering.

Does IRG7PH46UDPBF require a negative gate voltage for reliable turn-off?

No, IRG7PH46UDPBF achieves reliable turn-off with 0 V gate drive, but using −5 V to −8 V improves noise immunity and reduces turn-off delay dispersion. Negative bias is recommended in high-dv/dt environments such as multi-level inverters or systems with shared gate driver ground planes.

Can IRG7PH46UDPBF be paralleled with other IGBTs for higher current capacity?

Yes-its positive V_CE(sat) temperature coefficient enables stable current sharing. Successful paralleling requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling via shared heatsink. Derating to 80 % of total rated current per device is advised for long-term reliability.

Is the integrated diode in IRG7PH46UDPBF suitable for regenerative braking in motor drives?

Yes-the ultrafast soft-recovery diode supports bidirectional current flow and handles reverse recovery during regenerative events. Its 10 µs short-circuit rating and 45 A I_RRM allow safe operation during dynamic braking transients without external diode supplementation.
