Product details
Overview
IRG7PH50UPBF from Infineon (formerly International Rectifier) is a 1200 V, 90 A (TC = 100°C), trench-gate field-stop IGBT in TO-247AC package, optimized for high-voltage hard-switching applications including solar inverters and induction heating. It features 1.7 V typical VCE(on) at 50 A/25°C, 175°C maximum junction temperature, square RBSOA, and 100% ILM testing.
For engineers reviewing the IRG7PH50UPBF datasheet, IRG7PH50UPBF pinout, IRG7PH50UPBF application, or IRG7PH50UPBF equivalent, key selection criteria include its 1200 V VCES, low 290–440 nC total gate charge, 3600–4600 µJ Eon at 25°C, rugged 200 A clamped inductive current rating, and validated performance up to 175°C junction temperature.
Technical Context
This IGBT employs trench-gate and field-stop silicon architecture to achieve low conduction loss (VCE(on) = 1.7 V typ. @ 50 A/25°C) while maintaining robust switching behavior. Its positive VCE(on) temperature coefficient enables stable parallel operation, and full-square RBSOA supports reliable hard-switching under transient overloads.
Switching is characterized by 35–55 ns td(on), 40–60 ns tr, 430–500 ns td(off), and 45–65 ns tf at 25°C, with energy losses scaling predictably with gate resistance and collector current-Eon = 5600 µJ and Eoff = 3900 µJ at 175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200 V - Withstands DC bus voltages up to 960 V in hard-switched solar inverters with 20% safety margin. |
| IC @ TC = 100°C | 90 A - Sustains continuous output current in industrial UPS and welding systems with forced-air cooling. |
| VCE(on) typ. | 1.7 V @ 50 A/25°C - Enables <1.5% conduction loss at rated current in 600 V DC-link inverters. |
| Eoff @ 175°C | 3900 µJ - Determines snubber sizing and thermal design for high-temperature induction heating operation. |
| RθJC | 0.27 °C/W - Defines minimum heatsink interface requirement for 278 W power dissipation at TC = 100°C. |
| Qg | 290–440 nC - Sets gate driver peak current demand (>10 A) and influences switching speed vs. EMI trade-off. |
| ILM | 200 A @ VGE = 20 V - Validates short-circuit withstand capability during fault conditions without desaturation protection. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | High-side power terminal | Connected to DC bus (+) in half-bridge; electrically tied to heatsink via isolated tab; requires creepage clearance ≥4 mm. |

| Gate (G) | Control input | High-impedance MOS-controlled terminal; requires ±30 V absolute max rating; sensitive to ESD and ringing above 20 V. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(on) trench IGBT technology | 1.7 V typ. @ 50 A/25°C reduces conduction loss by ~25% versus planar 1200 V IGBTs in same package. |
| Square RBSOA | Validated at VCC = 960 V, TJ = 175°C - enables single-pulse operation without dynamic derating in UPS hold-up stages. |
| 100% ILM tested | Every unit verified for 200 A clamped inductive current - eliminates screening failure risk in welder primary switches. |
| Positive VCE(on) tempco | +1.0 mV/°C drift - ensures natural current sharing when paralleling multiple devices in solar string inverters. |
| Tight parameter distribution | VGE(th) = 3.0–6.0 V, Qg = 290–440 nC - simplifies gate driver design across production lots without recalibration. |

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 (TC = 100°C); higher VCE(on) = 2.2 V; lower Qg = 220 nC | Better switching efficiency at >20 kHz but higher conduction loss above 40 A RMS | Prefer for high-frequency resonant converters where Esw dominates; avoid in high-current UPS where VCE(on) loss dominates. |
| STMicroelectronics STGW100H12DL | 1200 V / 100 A (TC = 100°C); VCE(on) = 1.85 V; includes integrated NTC thermistor | Higher current rating enables derated use in 125 kW solar inverters; thermal monitoring simplifies protection logic | Select when system-level thermal monitoring is required; accept 0.15 V higher VCE(on) for built-in diagnostics. |
Compared with IXGN75N120B3 and STGW100H12DL, IRG7PH50UPBF offers the lowest VCE(on) among 1200 V 90 A-class IGBTs, making it optimal for conduction-loss-limited designs like medium-power UPS and welders, while trading off slightly higher Qg than ultra-fast alternatives.

FAQ
What is the maximum allowable gate-emitter voltage for IRG7PH50UPBF?
The absolute maximum continuous VGE is ±30 V. Operation beyond ±20 V risks permanent gate oxide damage. Gate drive circuits must limit transient overshoot using clamping diodes or active regulation, especially during fast turn-off with high dV/dt across the collector-emitter path.
Does IRG7PH50UPBF require a negative gate voltage for reliable turn-off?
No. The device is fully specified for 0 V to +15 V gate drive. However, applying –5 V to –10 V during off-state improves noise immunity and reduces Miller-induced false turn-on in high-dI/dt environments such as welding inverters with shared ground paths.
Can IRG7PH50UPBF be paralleled without external emitter resistors?
Yes-its positive VCE(on) temperature coefficient enables inherent current balancing. However, matched gate drive loop inductance (<5 nH difference per leg) and symmetrical PCB layout are mandatory; emitter resistors (0.1 Ω) are still recommended for production robustness in UPS applications.
What is the thermal resistance from junction to case (RθJC) for IRG7PH50UPBF?
RθJC is 0.27 °C/W maximum, measured per JEDEC JESD51-14 standard on flat greased surface. This value assumes full contact between the isolated metal tab and heatsink; thermal interface material thickness ≤ 0.1 mm and bond line pressure ≥ 50 psi are required to achieve datasheet-rated performance.
