Product details

Overview

IKQ120N60TXKSA1 from Infineon is a 600 V, 120 A TRENCHSTOP™ IGBT with integrated Emitter Controlled diode in a PG-TO247-3-46 package. It delivers 1.5 V typical V_CE(sat) at 120 A and 25°C, supports 175°C maximum junction temperature, withstands 5 µs short-circuit events, and features low gate charge (703 nC) for high-efficiency motor drives and UPS inverters.

For engineers reviewing the IKQ120N60TXKSA1 datasheet, IKQ120N60TXKSA1 pinout, IKQ120N60TXKSA1 application, or IKQ120N60TXKSA1 equivalent, key selection criteria include its soft-recovery anti-parallel diode (trr = 280 ns @ 25°C), positive V_CE(sat) temperature coefficient, and thermal resistance of 0.18 K/W (junction-to-case) for reliable thermal management in medium-frequency power converters.

Technical Context

This IGBT uses TRENCHSTOP™ and Fieldstop technology to achieve tight parameter distribution, high ruggedness, and stable performance across temperature. Its integrated Emitter Controlled diode enables soft, fast recovery (Q_rr = 3.50 µC @ 25°C) and reduces system-level EMI without external snubbers.

The device operates with a gate-emitter threshold voltage of 4.1–5.7 V and exhibits strong current handling up to 480 A pulsed, supported by a 0.30 K/W diode junction-to-case thermal resistance. Its switching energy (E_ts = 6.90 mJ @ 25°C) and low C_res (206 pF) enable efficient operation in hard-switched topologies up to ~20 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - Withstands DC bus voltages up to 400 V in 3-phase inverters with 30% margin for transients.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies (UPS)

IC Role / Device Role / Timing Role: Main switching device in inverter leg; handles bidirectional current via integrated diode during regeneration.

Use Value: Low V_CE(sat) and soft diode recovery reduce total losses by ~12% vs. standard 600 V IGBTs, lowering heatsink size and cooling cost.

Use Scenario: Online double-conversion UPS systems with 400 V DC bus and battery backup, requiring high reliability and fault tolerance.

IC Role / Device Role / Timing Role: Inverter-stage power switch; sustains short-circuit events for ≥5 µs to allow controller-level fault shutdown.

Use Value: 175°C rating and 5 µs t_SC enable fail-safe operation under overload, meeting UL 1778 and IEC 62040-1 safety margins.

General Purpose Inverters

Medium-Frequency Power Converters

Use Scenario: Modular solar string inverters and energy storage system (ESS) bi-directional converters operating at 8–16 kHz.

IC Role / Device Role / Timing Role: High-side switch in half-bridge topology; leverages integrated diode for freewheeling during dead-time.

Use Value: Low Q_G (703 nC) and C_res (206 pF) support clean, controllable switching with 3 Ω gate resistors, minimizing driver complexity.

Use Scenario: Induction heating supplies and welding inverters requiring 10–30 kHz operation with high peak current capability.

IC Role / Device Role / Timing Role: Primary switching element in resonant or hard-switched full-bridge; handles 480 A pulsed current during burst-mode operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT-in-DuoPack applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW120N60T	Same die, but PG-TO247-4-4 package with Kelvin emitter pin; 10% lower V_CE(sat) variation due to separate sense path.	Preferred for high-precision current control or paralleling where emitter inductance must be minimized.	Select IKW120N60T when gate drive stability under high di/dt or multi-device paralleling is critical.
FGH120T60SQD	ON Semiconductor part; 1.65 V V_CE(sat), higher Q_G (820 nC), no integrated diode - requires external ultrafast diode.	Suitable for designs already using discrete diodes or needing tighter trr control via component selection.	Choose FGH120T60SQD only if existing layout accommodates separate diode placement and higher gate drive power is acceptable.

Compared with IKQ120N60TXKSA1, IKW120N60T improves current sensing fidelity at the cost of layout complexity, while FGH120T60SQD trades integration for flexibility in diode selection-neither offers drop-in replacement without board-level changes.

FAQ

What is the maximum recommended gate-emitter voltage for IKQ120N60TXKSA1?

The absolute maximum gate-emitter voltage is ±20 V per datasheet specifications. Operation above +15 V or below –10 V risks permanent gate oxide damage. For reliable switching, Infineon recommends +15 V turn-on and –5 V to –10 V turn-off bias to suppress Miller-induced false triggering under high dv/dt conditions.

Does IKQ120N60TXKSA1 require an external freewheeling diode?

No. The device integrates a soft, fast-recovery Emitter Controlled diode rated for 120 A continuous forward current and 480 A pulsed current. This eliminates the need for an external diode in standard half-bridge or inverter leg configurations, simplifying PCB layout and reducing component count.

How does the 175°C maximum junction temperature impact thermal design?

A 175°C T_vj(max) allows higher case temperatures before derating begins, enabling smaller heatsinks or higher ambient operation (e.g., 70°C cabinet). With R_th(j-c) = 0.18 K/W, a 100°C case temperature yields only a 18°C junction rise-leaving 57°C margin to the 175°C limit at full 120 A conduction.

Can IKQ120N60TXKSA1 be paralleled for higher current capacity?

Yes-its positive V_CE(sat) temperature coefficient promotes natural current sharing. Successful paralleling requires matched gate drive impedance, symmetrical layout, and identical heatsink contact resistance. Derate total current by 15% versus sum of individual ratings to account for parameter spread and thermal coupling.
