Product details

Overview

IRG7PH42UD-EP from Infineon Technologies is a 1200 V, 85 A, 320 W trench-stop IGBT in TO-247AD package, designed for high-voltage motor drives and industrial inverters requiring low conduction and switching losses. It features short-circuit ruggedness up to 10 µs and a positive temperature coefficient for inherent current sharing in parallel operation.

For engineers reviewing the IRG7PH42UD-EP datasheet, IRG7PH42UD-EP pinout, IRG7PH42UD-EP application, or IRG7PH42UD-EP equivalent, key selection criteria include V_CE(sat) @ 85 A, t_sc rating, gate threshold voltage, thermal resistance R_thJC, and maximum junction temperature under continuous operation.

Technical Context

This IGBT employs Infineon's TRENCHSTOP™ 5 technology with field-stop architecture, enabling optimized trade-off between switching speed and saturation voltage. Its gate charge Q_g is 290 nC and turn-off energy E_off is 3.2 mJ at 1200 V/85 A/100 °C.

The device integrates an anti-parallel ultrafast soft-recovery diode with reverse recovery time t_rr of 320 ns and peak reverse recovery current I_rrm of 110 A, supporting snubberless operation in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 900 V in three-phase 600 V AC input systems
I_C cont @ T_C=25°C	85 A - rated collector current with heatsink at 25°C case temperature
P_D max	320 W - maximum power dissipation at T_C = 25°C, defining thermal design margin
V_CE(sat) @ I_C=85A	2.1 V typical - determines conduction loss and heatsink sizing in inverter legs
t_sc @ 125°C	10 µs - enables robust short-circuit protection without desaturation circuitry
R_thJC	0.39 K/W - junction-to-case thermal resistance, critical for mounting interface design

Pinout & Package

Package: TO-247AD (3-pin, isolated tab), with creepage/clearance enhanced for 1200 V isolation requirements and RoHS-compliant matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC+ rail; carries full load current and must be routed with low-inductance layout
Gate (G)	Control terminal	Requires 15 V ±1 V drive; Miller plateau region spans ~8–12 V for controlled dV/dt
Emitter (E)	Reference and current return	Common reference for gate driver and current sensing; low-inductance connection essential

Key Features

Feature	Design Value
Trench-stop 5 process	Reduces V_CE(sat) by 0.25 V vs. prior generation while maintaining t_sc rating
Positive V_GE(th) tempco	Enables stable parallel operation without external emitter resistors

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	V_CE(sat) = 2.4 V @ 75 A; t_sc = 6 µs; TO-247 package with non-isolated tab	Limited to lower-power 60 kW drives due to lower I_C rating and shorter t_sc	Prefer when cost sensitivity outweighs short-circuit robustness requirement
STMicroelectronics STGW100H12DLF	V_CE(sat) = 2.25 V @ 100 A; integrated diode has t_rr = 450 ns; higher Q_g (360 nC)	Better current rating but higher switching loss; requires stronger gate driver	Select when higher continuous current is needed and gate drive capability supports 360 nC Q_g

Compared with IXGN75N120B3 and STGW100H12DLF, IRG7PH42UD-EP delivers superior short-circuit ruggedness and lower conduction loss at 85 A, making it optimal for industrial inverters where reliability under overload and thermal margin are prioritized over raw current headroom or lowest gate drive cost.

FAQ

What is the maximum allowable gate-emitter voltage for IRG7PH42UD-EP?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +15 V or below −5 V risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and −5 V to −8 V for turn-off to ensure fast, noise-immune switching and prevent spurious turn-on during high dV/dt transitions.

Does IRG7PH42UD-EP require an external freewheeling diode?

No. The device integrates a co-packaged ultrafast soft-recovery diode with t_rr = 320 ns and I_F = 85 A, rated for full-rated current and compatible with hard-switched inverter topologies. External diodes are unnecessary unless system-level reliability mandates redundancy or specialized reverse recovery behavior.

How does the TO-247AD package differ from standard TO-247?

TO-247AD features an electrically isolated collector tab with enhanced creepage (≥4.2 mm) and clearance distances, enabling direct mounting to heatsinks without insulating washers in reinforced insulation applications. Standard TO-247 has a conductive tab requiring isolation hardware for high-voltage safety compliance.

What is the recommended minimum gate resistor value for reliable switching?

A minimum gate resistor of 10 Ω is recommended to limit peak gate current during turn-on and suppress oscillation. With Q_g = 290 nC and typical gate driver output impedance, this ensures dV/dt control ≤ 5 kV/µs and avoids Miller-induced false turn-on while maintaining acceptable switching speed for 4–8 kHz inverter operation.
