Product details
Overview
IKQ120N120CH7XKSA1 from Infineon is a high-speed 1200 V, 120 A TRENCHSTOP™ IGBT 7 co-packed with a full-rated 120 A ultra-fast recovery emitter-controlled 7 Rapid diode in PG-TO247-3-PLUS package. It delivers VCE(sat) = 1.7 V at 25°C, trr = 146 ns (25°C), and Qrr = 3.45 µC, enabling high-efficiency hard-switching in industrial UPS, EV-charging, and string inverters.
For engineers reviewing the IKQ120N120CH7XKSA1 datasheet, IKQ120N120CH7XKSA1 pinout, IKQ120N120CH7XKSA1 application, or IKQ120N120CH7XKSA1 equivalent, key selection criteria include its positive VCE(sat) temperature coefficient for stable paralleling, low switching losses (Eon = 7.77 mJ, Eoff = 2.95 mJ @ 600 V/120 A), and 175°C maximum junction temperature rating.
Technical Context
This device implements Infineon's TRENCHSTOP™ IGBT 7 silicon architecture optimized for high-frequency hard-switching topologies-including 2-level inverters and 3-level NPC/T-type configurations-by minimizing tail current and gate charge (QG = 834 nC) while maintaining robust short-circuit withstand time (tsc ≥ 3 µs).
The integrated 7 Rapid diode features soft commutation, ultra-low Qrr, and controlled reverse recovery (Irrm = 46 A, dIrr/dt = −444 A/µs), reducing voltage overshoot and EMI in bidirectional power stages without requiring external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE | 1200 V - supports DC-link voltages up to 1000 V in 3-phase rectified systems with safety margin. |
| IC | 120 A continuous - rated for sustained conduction at Tc = 100°C, matching typical module-level thermal design targets. |
| VCE(sat) | 1.7 V @ 25°C - enables low conduction loss in high-current paths, critical for >98% system efficiency targets. |
| trr | 146 ns @ 25°C - ensures fast, soft diode turn-off with minimal voltage spike during IGBT turn-on in half-bridge legs. |
| Qrr | 3.45 µC @ 25°C - reduces reverse recovery energy (Erec = 1.02 mJ), lowering total switching loss and heatsink requirements. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IKW120N120CS7 | Same 1200 V/120 A rating but TO247-4L package with Kelvin emitter; lower VCE(sat) (1.65 V) and QG (750 nC); no integrated diode. | Requires external diode; suited for ultra-high-efficiency designs where gate drive precision and lowest conduction loss are prioritized over integration. | Select when using active gate driving with Kelvin sensing and discrete diode optimization is acceptable. |

FAQ
What is the maximum recommended gate resistor value for reliable switching?
The datasheet specifies RG(off) ≥ 3.5 Ω for safe SOA operation. For standard 5.6 Ω gate resistors, turn-off delay is 544 ns at 25°C and 613 ns at 175°C. Higher values increase switching time and losses; values below 3.5 Ω risk exceeding turn-off SOA limits under high VCC and temperature.
Does this device require a negative gate voltage for turn-off?
No. The device is fully compatible with 0 V / +15 V gate drive. Negative voltage is not required, though −5 V to −8 V may improve noise immunity in high-dv/dt environments. The absolute maximum VGE rating is ±20 V, and transient rating allows ±25 V for ≤0.5 µs.
How is thermal resistance measured for the co-packed diode?
The diode's Rth(j-c) is specified separately as 0.25–0.33 K/W (typ./max.), measured from diode junction to case under defined test conditions (JEDEC JESD51-14). This value is independent of the IGBT's 0.15–0.19 K/W rating and must be used for diode-specific thermal calculations.
Can this IGBT be paralleled with other IKQ120N120CH7XKSA1 units?
Yes-its positive VCE(sat) temperature coefficient ensures inherent current sharing. Parallel operation requires matched gate drive layout (equal trace inductance/resistance), identical heatsinking, and symmetrical busbar connections to avoid dynamic imbalance. No external emitter resistors are needed.
