Product details

Overview

IRG7PH46UPBF from Infineon (formerly International Rectifier) is a 1200 V, 75 A (T_C = 100°C), trench-gate field-stop IGBT in TO-247AC package, optimized for high-voltage hard-switching applications requiring low conduction loss and rugged RBSOA. It delivers V_CE(on) = 1.7 V (typ., T_J = 25°C), 175°C max junction temperature, and full square RBSOA at 960 V with clamped inductive load capability up to 160 A.

For engineers reviewing the IRG7PH46UPBF datasheet, IRG7PH46UPBF pinout, IRG7PH46UPBF application, or IRG7PH46UPBF equivalent, key selection criteria include its 1200 V blocking rating, 220–320 nC total gate charge, 0.32 °C/W junction-to-case thermal resistance, and verified performance in solar inverters and UPS systems operating above 600 V DC bus.

Technical Context

This IGBT employs trench-gate + field-stop structure to achieve low V_CE(on) (1.7 V typ. @ 40 A, 15 V_GE, 25°C) while maintaining positive temperature coefficient for stable parallel operation. Its square RBSOA supports reliable clamped inductive switching up to 160 A with V_GE = 20 V drive.

Switching behavior is characterized by 45–65 ns turn-on delay, 40–55 ns rise time, and 410–445 ns turn-off delay at 25°C; at 175°C, E_off rises to 3020 μJ (RG = 10 Ω), confirming thermal robustness for high-temperature industrial operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - Enables use in 1000 V-class DC-link systems (e.g., solar string inverters, medium-voltage UPS).
I_C @ T_C = 100°C	75 A - Continuous silicon-limited current at heatsink temperature of 100°C, defining practical thermal design limit.
V_CE(on) (typ.)	1.7 V @ 40 A, 15 V_GE, 25°C - Low conduction loss enables >98% efficiency in 10–20 kHz hard-switched converters.
E_off (typ.)	1780 μJ @ 40 A, 600 V, 25°C - Quantifies energy dissipated during turn-off; critical for snubber and thermal sizing.
R_θJC	0.32 °C/W - Junction-to-case thermal resistance directly determines heatsink requirement for given power loss.
Q_g	220–320 nC - Total gate charge defines driver strength needed (e.g., ≥2 A peak for 100 ns switching).
T_J(max)	175°C - Maximum allowable junction temperature supports operation in sealed enclosures or high ambient environments.

Pinout & Package

IRG7PH46UPBF uses the industry-standard TO-247AC package (3-lead, isolated tab), with collector connected to the metal tab for direct heatsinking. Pin assignment follows standard IGBT layout: Gate (G), Collector (C), Emitter (E), with pin 1 = Gate, pin 2 = Collector, pin 3 = Emitter when viewed with leads down and marking side up.

Pin/Terminal	Circuit Role	Design Meaning
G	Control input	Receives gate drive voltage (±30 V max); requires low-inductance path to minimize switching overshoot.
C	High-side power output	Connected to heatsink tab; carries full load current and must be electrically isolated from chassis unless system ground-referenced.
E	Power return / reference	Serves as emitter reference for gate drive; must be routed with minimal loop inductance to reduce voltage spikes during switching.

Key Features

Feature	Design Value
Low V_CE(on) trench IGBT technology	1.7 V typical saturation voltage reduces conduction losses by ~25% vs. planar IGBTs at same current density.
Square RBSOA	Rated for full 1200 V clamped inductive switching at 175°C junction temperature-enables reliable short-circuit handling without derating.
Positive V_CE(on) temp. coefficient	Ensures inherent current sharing in parallel configurations without external ballasting resistors.
100% I_LM tested	Every unit validated for 160 A clamped inductive current-guarantees robustness in welding and UPS overload conditions.
Tight parameter distribution	Gate threshold voltage (3.0–6.0 V) and V_CE(on) variation minimized-simplifies gate driver design and improves system consistency.

Applications

Solar Inverter

Uninterruptible Power Supply (UPS)

Use Scenario: Three-phase string inverter stage converting 800–1000 V DC to 230 V AC grid-tie output.

IC Role / Device Role / Timing Role: High-side IGBT in NPC or T-type three-level topology, switching at 10–16 kHz with sinusoidal PWM.

Use Value: 1200 V rating allows direct connection to 1000 V DC strings; low V_CE(on) maintains >98.5% conversion efficiency at full load.

Use Scenario: Online double-conversion UPS delivering clean 230 V AC during utility outage, with battery-fed DC link.

IC Role / Device Role / Timing Role: Inverter-stage IGBT in full-bridge configuration, operating continuously at 5–10 kHz with overcurrent protection.

Use Value: Square RBSOA and 160 A I_LM rating support 150% overload for 60 s without failure-critical for generator-startup transients.

Induction Heating

Industrial Welding

Use Scenario: Resonant half-bridge inverter driving 20–100 kHz induction coil for metal heating in forging or brazing.

IC Role / Device Role / Timing Role: Main switching device in ZVS resonant topology, handling high di/dt and repetitive hard commutation.

Use Value: Low Q_gc/Q_ge ratio (≈2.8:1) minimizes Miller-induced false turn-on; tight g_fe tolerance ensures consistent gain across production lots.

Use Scenario: IGBT-based inverter welder supplying pulsed DC or AC output for MIG/TIG processes with dynamic load changes.

IC Role / Device Role / Timing Role: Primary power switch in primary-side inverter, subjected to frequent short-circuit events and high peak currents.

Use Value: 100% I_LM testing at 160 A guarantees survival under arc-short conditions; 175°C T_J(max) supports compact heatsink designs.

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	1200 V/75 A, but higher V_CE(on) (2.1 V typ.), lower Q_g (180 nC), TO-247AD package (non-isolated tab)	Lacks full square RBSOA; rated only for 120 A I_LM; not qualified for 175°C continuous operation	Prefer where gate drive power is constrained and heatsink isolation is not required.
STMicroelectronics STGW75H120DF	1200 V/75 A, V_CE(on) = 1.85 V (typ.), Q_g = 240 nC, TO-247 long leads; includes integrated anti-parallel diode	Diode has higher V_F (2.2 V) and slower recovery than discrete ultrafast diodes used with IRG7PH46UPBF	Choose when board space is limited and diode integration simplifies layout-accept trade-off in diode loss.

Compared with IXGN75N120B3 and STGW75H120DF, IRG7PH46UPBF offers superior RBSOA margin and tighter V_CE(on) distribution, making it preferred for mission-critical UPS and solar inverters where reliability under transient overload is non-negotiable.

FAQ

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

The datasheet specifies RG = 10 Ω for switching loss characterization at TJ = 175°C. For hard-switched applications, RG ≤ 15 Ω is recommended to maintain safe dv/dt control and avoid shoot-through. Higher values (>22 Ω) increase E_off significantly-measured rise from 1780 μJ to >3000 μJ at RG = 22 Ω per Figure 15.

Does IRG7PH46UPBF include an integrated freewheeling diode?

No. IRG7PH46UPBF is a standalone IGBT die in TO-247AC package with no integrated diode. External ultrafast or SiC Schottky diodes must be used in anti-parallel configuration. The device is optimized for pairing with diodes having < 50 ns reverse recovery time and low Q_rr.

Can this IGBT be operated with ±15 V gate drive?

Yes. The absolute maximum V_GE is ±30 V, and the datasheet characterizes V_CE(on), switching times, and losses at V_GE = +15 V / –15 V. Using –15 V turn-off bias improves noise immunity and reduces Miller-induced turn-on risk in high-dv/dt environments.

Is the TO-247AC package electrically isolated?

Yes. The TO-247AC variant features an electrically isolated metal tab (collector-connected), allowing direct mounting to a grounded heatsink without additional insulation. This differs from TO-247AD, where the tab is electrically connected to the collector lead and requires insulating hardware.
