Product details

Overview

IRG7PH42UD1PBF from Infineon Technologies is a 1200 V, 85 A, 313 W trench gate field-stop IGBT in TO-247AC package, designed for high-voltage motor drives and industrial inverters operating up to 20 kHz switching frequency. It features low V_CE(sat) of 2.1 V at 85 A and T_j = 150 °C, integrated anti-parallel FRD with soft recovery (t_rr = 320 ns), and positive temperature coefficient for inherent current sharing.

For engineers reviewing the IRG7PH42UD1PBF datasheet, IRG7PH42UD1PBF pinout, IRG7PH42UD1PBF application, or IRG7PH42UD1PBF equivalent, key selection criteria include V_CE(sat), short-circuit withstand time (10 µs), thermal resistance R_th(j-c) (0.4 K/W), gate charge Q_G (320 nC), and FRD reverse recovery behavior in hard-switched bridge topologies.

Technical Context

This IGBT employs Infineon's TrenchStop™ 7 technology with field-stop layer optimization for reduced conduction and switching losses. Its gate threshold voltage V_GE(th) is 5.5 V (min) at 25 °C, enabling robust noise immunity in noisy industrial environments.

The integrated fast-recovery diode has forward voltage V_F = 2.2 V at 85 A and exhibits soft, low-noise turn-off with peak reverse recovery dv/dt < 100 V/ns - critical for EMI-sensitive variable-frequency drives and UPS systems.

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 20% margin
I_C cont @ T_c=25°C	85 A - rated continuous collector current with heatsink at 25 °C case temperature
P_D max	313 W - maximum power dissipation at T_c = 25 °C, defining thermal design envelope
V_CE(sat)	2.1 V @ I_C=85 A, V_GE=15 V, T_j=150°C - directly determines conduction loss in inverter leg
t_sc	10 µs @ V_CE=600 V, V_GE=15 V, T_j=150°C - defines safe single-pulse short-circuit capability without desaturation protection
Q_G	320 nC @ V_GE=0–15 V - determines gate driver peak current requirement (≥4 A for 80 ns rise time)
R_th(j-c)	0.4 K/W - junction-to-case thermal resistance, used to calculate die temperature from measured case temp

Pinout & Package

TO-247AC package: 3-pin through-hole outline with isolated tab (collector connected to tab), standard lead spacing and creepage/clearance compliant for 1200 V systems.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main high-side current path	Electrically connected to metal tab; requires insulated mounting and thermal interface to heatsink
Gate	Control terminal for MOS-controlled bipolar conduction	High-impedance input requiring low-inductance gate loop and negative turn-off bias (−5 V typical) for noise immunity
Emiter	Reference node for gate drive and current sensing	Shared emitter node for IGBT and integrated FRD; must be low-inductance connection to shunt/sense resistor

Key Features

Feature	Design Value
TrenchStop™ 7 process	Enables simultaneous reduction of V_CE(sat) and switching losses vs. prior generations
Integrated FRD with soft recovery	t_rr = 320 ns, softness factor ≥1.2 - reduces voltage overshoot and EMI in freewheeling paths
Positive V_CE(sat) temperature coefficient	Ensures natural current balancing in parallel-connected devices without external ballasting resistors
10 µs short-circuit rating	Allows use in systems without active desaturation detection circuitry under defined test conditions

Applications

Use Scenario: Online double-conversion UPS with 400 V DC link supplying 230 V AC output to critical IT loads.

IC Role / Device Role / Timing Role: Inverter-stage IGBT in full-bridge configuration, handling bidirectional energy flow during battery charging and grid backup modes.

Use Value: 1200 V rating enables direct integration with high-voltage battery stacks (e.g., 360–400 V nominal), eliminating DC/DC stage.

Solar String Inverters

Induction Heating Systems

Use Scenario: 10–25 kW string inverter converting PV DC output (600–1000 V) to grid-synchronized AC.

IC Role / Device Role / Timing Role: High-side switch in H-bridge output stage, switching at 12–18 kHz with unipolar modulation.

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), lower Q_G (240 nC), no integrated diode	Requires external ultra-fast diode; better suited for resonant topologies with precise diode control	Prefer when discrete diode selection is needed for optimized recovery tail control
STMicroelectronics STGW100H12DLF	Same V_CE/I_C rating, higher t_sc (12 µs), softer FRD (t_rr = 380 ns)	Better short-circuit robustness but slightly higher conduction loss	Prefer where extended fault-clearing time is required without desat detection

Compared with IXGN75N120B3 and STGW100H12DLF, IRG7PH42UD1PBF offers the lowest conduction loss and integrated soft-recovery diode - optimal for space-constrained industrial inverters where board area and component count must be minimized.

FAQ

What is the maximum recommended gate-emitter voltage for IRG7PH42UD1PBF?

The absolute maximum gate-emitter voltage is ±20 V. For reliable operation, Infineon specifies V_GE = +15 V for turn-on and −5 V to −8 V for turn-off. Exceeding +15 V increases leakage and risk of gate oxide degradation; insufficient negative bias raises susceptibility to false turn-on from dv/dt coupling in high-power layouts.

Does IRG7PH42UD1PBF require an external freewheeling diode?

No. IRG7PH42UD1PBF integrates a co-packaged fast-recovery diode with soft recovery characteristics (t_rr = 320 ns, softness factor ≥1.2). This eliminates the need for an external diode in standard inverter leg configurations, provided the diode's current and thermal ratings meet the application's freewheeling demands.

How does the 10 µs short-circuit rating translate to real-world protection requirements?

The 10 µs rating is measured under standardized lab conditions (V_CE = 600 V, V_GE = 15 V, T_j = 150 °C). In practice, this means the device can survive brief overcurrent events - such as motor stall or output short - only if external protection (e.g., fast desaturation detection with < 2 µs response) limits total fault duration well below 10 µs to prevent thermal runaway.

Can IRG7PH42UD1PBF be paralleled for higher current capacity?

Yes - its positive V_CE(sat) temperature coefficient enables stable current sharing without external emitter resistors. Successful paralleling requires matched gate drive layout (identical trace length/inductance), symmetrical thermal mounting, and individual gate resistors (10–22 Ω) to damp oscillation. Derating to ≤70% of total rated current per device is recommended for long-term reliability.
