Product details
Overview
IRG7CH35UED from Infineon Technologies is a 1200 V, 35 A ultra-fast IGBT in TO-247 package with integrated anti-parallel diode, designed for high-frequency switching in industrial motor drives and UPS inverters. It features 2.5 V typical VCE(sat) at 25 °C, 150 ns turn-off time, and 175 °C maximum junction temperature.
For engineers reviewing the IRG7CH35UED datasheet, IRG7CH35UED pinout, IRG7CH35UED application, or IRG7CH35UED equivalent, key selection criteria include VCE(sat) stability across temperature, short-circuit withstand time (10 µs), gate charge (125 nC), and diode reverse recovery characteristics for hard-switching topologies.
Technical Context
This IGBT employs Infineon's TRENCHSTOP™ 7 silicon technology, delivering reduced conduction and switching losses simultaneously. Its optimized carrier lifetime control enables fast turn-off without excessive voltage overshoot in snubberless operation.
The integrated diode is a soft-recovery, ultrafast freewheeling diode with 60 ns reverse recovery time and low Qrr, minimizing commutation losses in bridge-leg configurations used in three-phase inverters and servo drives.
Key Specifications

| IC (TC=80°C) | 35 A - continuous collector current rating under standard heatsink conditions |
| VCE(sat) @ 25°C | 2.5 V typical - reduces conduction loss in 16–20 kHz PWM motor control stages |
| tfall | 150 ns - enables high-frequency switching while maintaining EMI compliance in compact designs |
| QG | 125 nC - determines gate driver power requirement and influences switching speed control |
| tsc | 10 µs - defines safe single-pulse short-circuit capability without desaturation protection |
| Tj max | 175 °C - allows operation in high-ambient environments such as enclosed industrial cabinets |
Pinout & Package

Applications
| Industrial Motor Drives | Uninterruptible Power Supplies (UPS) |
|---|---|
Use Scenario: Variable-frequency drives for 7.5–15 kW AC induction motors in HVAC and pump systems. IC Role / Device Role / Timing Role: Main inverter switch in 2-level or 3-level NPC topology; switches at 8–16 kHz with sinusoidal PWM. Use Value: Low VCE(sat) and fast turn-off reduce thermal stress on heatsinks, enabling fanless enclosure designs in space-constrained installations. | Use Scenario: Online double-conversion UPS systems delivering clean 50/60 Hz sine-wave output with <5 ms transfer time. IC Role / Device Role / Timing Role: Inverter-stage IGBT in full-bridge output stage; handles bidirectional energy flow during battery backup mode. Use Value: Integrated diode with soft recovery minimizes shoot-through risk during zero-crossing transitions, improving waveform fidelity and reducing filter component count. |
| Servo Amplifiers | Renewable Energy Inverters |
Use Scenario: High-bandwidth current-loop amplifiers for permanent magnet synchronous motors in CNC and robotics. IC Role / Device Role / Timing Role: Half-bridge leg switch operating at 20 kHz with precise dead-time control. Use Value: Tight VCE(sat) tolerance (±0.2 V) ensures matched current sharing between parallel devices, critical for torque ripple suppression. | Use Scenario: String inverters converting DC from solar arrays (600–1000 V) to grid-synchronized AC. IC Role / Device Role / Timing Role: DC-link switching device in boost or inverter stage; operates with unidirectional current and high dv/dt immunity. Use Value: 1200 V blocking rating provides 2× safety margin over 600 V PV string voltage, supporting long-string configurations without series stacking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage IGBT applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGW40H120F2 | Higher VCE(sat) (2.8 V typ), lower QG (95 nC), same 1200 V/35 A rating | Optimized for lower gate drive power but higher conduction loss; better for low-duty-cycle peak loads | Prefer when gate driver supply is limited or thermal design prioritizes switching over conduction loss |
| IXYS IXGN35N120B3 | Discrete IGBT + separate diode; higher tsc (15 µs); no integrated diode | Requires external diode selection and layout optimization; preferred where diode recovery tail must be tuned independently | Choose when system-level EMI tuning or diode parameter customization is required |
Compared with STGW40H120F2 and IXGN35N120B3, IRG7CH35UED offers lowest conduction loss and simplified layout via monolithic integration, making it optimal for thermally constrained, high-volume industrial inverters where board space and BOM count matter.

FAQ
What is the recommended gate resistor value for IRG7CH35UED in a 16 kHz motor drive?
A 10 Ω non-inductive gate resistor is recommended for balanced switching speed and EMI control at 16 kHz. This value limits peak gate current to ~1.5 A while achieving ~200 ns rise/fall times with a 15 V gate drive, avoiding oscillation and ensuring robust noise immunity in noisy industrial environments.
Does IRG7CH35UED require an external freewheeling diode?
No. IRG7CH35UED integrates a soft-recovery ultrafast diode rated for 35 A average forward current and 1200 V reverse blocking. Its 60 ns reverse recovery time and low Qrr eliminate the need for an external diode in standard half-bridge or full-bridge configurations used in motor drives and UPS systems.
What is the maximum allowable gate-emitter voltage for reliable operation?
The absolute maximum gate-emitter voltage is ±20 V. For reliable long-term operation, Infineon specifies −10 V to +15 V as the functional range. A gate drive of +15 V ensures low VCE(sat), while −10 V provides robust noise margin against false turn-on during high dv/dt transients in bridge configurations.
How does IRG7CH35UED perform under short-circuit conditions?
IRG7CH35UED sustains 10 µs of short-circuit current at 600 V and 15 V gate drive before failure. This allows time for external protection circuits (e.g., desaturation detection with 2–5 µs response) to trigger shutdown. No internal short-circuit protection circuitry is present-it relies on system-level fault handling.
