Product details
Overview
IKQ75N120CS6XKSA1 from Infineon is a 1200 V, 75 A TRENCHSTOP™ IGBT6 with integrated soft-recovery anti-parallel diode in PG-TO247-3-46 package. It delivers high-speed soft switching, low gate charge (530 nC), and 175 °C max junction temperature for industrial UPS, solar string inverters, and welding systems requiring robust hard-switching performance.
For engineers reviewing the IKQ75N120CS6XKSA1 datasheet, IKQ75N120CS6XKSA1 pinout, IKQ75N120CS6XKSA1 application, or IKQ75N120CS6XKSA1 equivalent, key selection criteria include VCE(sat) = 1.85 V @ 25 °C, Eoff = 2.95 mJ, trr = 440 ns, Qrr = 4.70 µC, and Rth(j-c) = 0.17 K/W for thermal design and paralleling reliability.
Technical Context
This sixth-generation IGBT uses Trench & Fieldstop architecture to achieve low conduction loss and controlled tail current, enabling efficient operation in both hard-switched and resonant topologies. Its positive VCE(sat) temperature coefficient ensures stable current sharing during parallel operation.
The co-packed diode features very soft reverse recovery (trr = 440 ns, Qrr = 4.70 µC @ 25 °C) and low peak reverse recovery current (Irrm = 27.0 A), minimizing voltage overshoot and EMI generation during commutation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE | 1200 V - supports DC bus voltages up to 1000 V in three-level solar inverters and industrial UPS. |
| IC | 75 A continuous @ Tc = 100 °C - enables compact heatsink sizing in high-power converters. |
| VCE(sat) | 1.85 V @ 75 A, 25 °C - reduces conduction loss and improves system efficiency at rated load. |
| QG | 530 nC - lowers gate drive power requirement and simplifies driver selection. |
| Eoff | 2.95 mJ @ 600 V, 75 A, 25 °C - enables high-frequency switching with manageable turn-off losses. |
| Rth(j-c) | 0.17 K/W - allows direct mounting to heatsink with predictable thermal resistance for junction-to-case path. |
| trr / Qrr | 440 ns / 4.70 µC @ 25 °C - minimizes diode-induced voltage spikes and snubber stress in inductive switching. |
Pinout & Package
Package: PG-TO247-3-46 - standard 3-pin through-hole package with isolated collector tab, optimized for high-current, high-voltage industrial applications and compatible with automated assembly and thermal interface materials.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-side current path | Electrically connected to metal tab; requires insulated mounting and direct heatsink contact for thermal management. |
| Gate (G) | Control input for IGBT channel | Low-impedance MOS-controlled terminal; sensitive to ESD and requires < ±20 V gate drive with proper RC snubbing. |
| Emitter (E) | Reference node for gate drive and current return | Shared emitter for IGBT and anti-parallel diode; must be routed with low-inductance layout to suppress voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed soft switching | Reduces EMI and voltage overshoot via controlled fall time (tf = 31 ns) and low tail current. |
| Positive VCE(sat) tempco | Enables stable current sharing in parallel configurations without external current-balancing resistors. |
| Integrated anti-parallel diode | Soft-recovery diode with trr = 440 ns and Qrr = 4.70 µC eliminates need for discrete freewheeling diode. |
| 175 °C maximum junction temperature | Extends usable thermal margin in high-ambient environments such as enclosed welders or energy storage cabinets. |
| Pb-free, RoHS-compliant plating | Meets industrial environmental compliance requirements without compromising solderability or long-term reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IKW40N120H3 | 1200 V, 40 A, lower current rating; higher VCE(sat) (2.1 V); no integrated diode. | Suitable for lower-power welders or auxiliary inverters where discrete diode placement is acceptable. | Select when board space permits separate diode layout and thermal budget allows higher conduction loss. |
| FF75R12RT4 | 1200 V, 75 A, 4-pin TO247 package with Kelvin emitter; lower Eoff (2.3 mJ); higher cost. | Better suited for high-frequency, high-precision motor drives requiring ultra-low switching loss and gate control fidelity. | Choose when gate drive stability and sub-µs timing accuracy outweigh cost and layout complexity constraints. |
Compared with IKW40N120H3, IKQ75N120CS6XKSA1 offers higher current capability and integrated diode convenience; versus FF75R12RT4, it trades Kelvin emitter precision for lower BOM count and cost-ideal for industrial UPS and solar where robustness and integration dominate.

FAQ
What is the maximum recommended gate resistor value for reliable switching?
The datasheet specifies RG(on)/RG(off) = 4.0 Ω for characterization, but practical designs use 5–10 Ω to balance switching speed and voltage overshoot. At 175 °C, td(off) increases to 370 ns and Eoff rises to 5.30 mJ-so higher RG values (>12 Ω) risk excessive loss and thermal runaway in high-frequency operation.
Can IKQ75N120CS6XKSA1 be used in parallel configurations?
Yes-its positive VCE(sat) temperature coefficient ensures inherent current balancing across multiple devices. Successful parallel operation requires matched gate drive paths, symmetrical PCB layout, and identical heatsink mounting pressure to maintain uniform thermal resistance (Rth(j-c) = 0.17 K/W).
Does the integrated diode support reverse conduction in bidirectional topologies?
Yes-the co-packed diode is rated for IF = 75 A continuous and IFpuls = 300 A, with soft recovery (trr = 440 ns, Qrr = 4.70 µC). It is fully qualified for freewheeling and regenerative braking in Vienna rectifiers and bidirectional DC-DC converters.
What is the short-circuit withstand capability under real-world conditions?
Rated for tSC = 3 µs at VGE = 15 V and VCC ≤ 500 V, with ≤1000 allowed events and ≥1 s between faults. This applies only when junction temperature is ≤150 °C-designs must include fast desaturation detection and active shutdown to meet this spec reliably.
