Product details

Overview

IRG7PH42UD1-EP from Infineon Technologies is a 1200 V, 85 A, TrenchStop IGBT with co-packaged fast recovery diode in TO-247-3 package, designed for high-voltage motor drives and industrial inverters operating up to 20 kHz switching frequency.

For engineers reviewing the IRG7PH42UD1-EP datasheet, IRG7PH42UD1-EP pinout, IRG7PH42UD1-EP application, or IRG7PH42UD1-EP equivalent, key selection criteria include V_CE(sat) @ 85 A (2.1 V), E_off @ 1200 V/85 A (3.2 mJ), diode reverse recovery Q_rr (1.9 µC), and maximum junction temperature (175 °C).

Technical Context

This IGBT uses TrenchStop 7 silicon technology with field-stop structure and optimized carrier lifetime control to achieve low conduction and switching losses simultaneously. Its integrated diode features soft recovery characteristics and low Q_rr, reducing voltage overshoot during turn-off.

The device supports gate drive voltages from –10 V to +20 V, with recommended V_GE(th) of 5.5 V and typical Miller plateau at 7.5 V. It is qualified per MIL-STD-750 Method 2074 for enhanced reliability in harsh environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 800 V in three-phase inverter topologies
I_C cont @ T_c = 25°C	85 A - continuous collector current rating at case temperature 25°C
V_CE(sat) @ I_C = 85 A	2.1 V - low saturation voltage reduces conduction loss in high-current operation
E_off @ 1200 V / 85 A	3.2 mJ - measured at 1200 V V_CE, 85 A I_C, 25°C, defines switching energy loss during turn-off
Q_rr (diode)	1.9 µC - low reverse recovery charge minimizes diode-induced voltage spikes
T_j max	175 °C - enables operation in high-ambient industrial environments with derating

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 IXGN80N120B3	Higher V_CE(sat) (2.4 V @ 80 A), lower E_off (2.7 mJ), TO-247-3 package	Better suited for hard-switched ZVS topologies due to lower E_off	Prefer when minimizing turn-off loss dominates over conduction loss
STMicroelectronics STGW80H120DF2	Lower I_C rating (80 A), higher Q_rr (2.8 µC), same V_CE max	Requires larger snubber network in high-dI/dt induction heating	Choose only if cost sensitivity outweighs diode recovery performance needs

Compared with IXGN80N120B3 and STGW80H120DF2, IRG7PH42UD1-EP delivers the best balance of conduction efficiency, soft switching behavior, and ruggedness-making it optimal for industrial drives where thermal margin and long-term reliability are critical.

FAQ

What gate resistor value is recommended for IRG7PH42UD1-EP in a 10 kHz inverter application?

A 10 Ω gate resistor is recommended for 10 kHz operation to balance switching speed and voltage overshoot. This value limits dV/dt to ≤10 V/ns while keeping E_on + E_off within 5.1 mJ at 1200 V/85 A, per Infineon's AN2017-05 application note.

Does IRG7PH42UD1-EP require negative gate voltage for reliable turn-off?

Yes-Infineon specifies –5 V to –10 V gate-emitter voltage for robust turn-off under high dV/dt conditions. This prevents false triggering from Miller-induced voltage spikes, especially in bridge configurations with fast-rising V_CE.

Can IRG7PH42UD1-EP replace IRG7PH42U in existing designs?

Yes-the "-EP" suffix denotes enhanced product qualification per MIL-STD-750 Method 2074, with identical electrical specs and pinout. No layout or drive circuit changes are needed; the upgrade improves long-term reliability in vibration-prone or thermally cycled environments.

What is the maximum allowable gate-emitter voltage for IRG7PH42UD1-EP?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +20 V risks permanent oxide damage; below –10 V increases gate leakage. Infineon recommends +15 V turn-on and –8 V turn-off for optimal safe operating area and lifetime.
