Product details

Overview

IKW50N65H5AXKSA1 from Infineon is a 650V, 50A high-speed TRENCHSTOP™ 5 IGBT copacked with a RAPID 1 fast/soft antiparallel diode in a PG-TO247-3 package. It delivers 1.66V V_CE(sat) at 50A/25°C, 116nC gate charge, and 175°C max junction temperature, enabling high-efficiency hard-switching and resonant topologies in industrial power converters.

For engineers reviewing the IKW50N65H5AXKSA1 datasheet, IKW50N65H5AXKSA1 pinout, IKW50N65H5AXKSA1 application, or IKW50N65H5AXKSA1 equivalent, key selection criteria include its low switching energy (0.14–0.85mJ), soft diode recovery (Q_rr = 0.26–1.03µC), and AEC-Q101 qualification for rugged industrial deployment.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop technology optimized for high-speed switching with minimized tail current and reduced E_off. Its integrated RAPID 1 diode features low Q_rr, soft reverse recovery (dI_rr/dt ≤ –1380 A/µs), and low V_F (1.50–1.54V), reducing system losses in bidirectional energy transfer.

The device operates across –40°C to +175°C junction range with 0.55 K/W IGBT and 1.50 K/W diode junction-to-case thermal resistance. Gate threshold voltage is tightly specified (3.2–4.8V), ensuring robust noise immunity and predictable turn-on behavior under varying drive conditions.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed IGBT + diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65H5	40A rated current, identical V_CE, V_CE(sat), and Q_G; lower I_C and P_tot (220W vs. 270W)	Targeted at 2–3kW systems; less thermal margin in high-duty-cycle operation	Select when system peak current stays below 40A and board space or cost optimization is prioritized
FGH40N60UF	600V rating, 40A, older UFT technology; higher V_CE(sat) (1.8V), slower trr (100ns), no AEC-Q101	Legacy industrial designs where 650V margin is not required and qualification is not mandated	Choose only for drop-in replacement in existing 600V designs with relaxed efficiency and reliability targets

Compared with IKW40N65H5 and FGH40N60UF, IKW50N65H5AXKSA1 offers superior power handling (50A/270W), best-in-class softness (Q_rr < 1.03µC), and automotive-grade qualification-making it optimal for new 4–7kW industrial and renewable energy designs demanding longevity and high efficiency.

FAQ

What is the maximum recommended gate-emitter voltage for continuous operation?

The absolute maximum continuous gate-emitter voltage is ±20V. Transient peaks up to ±30V (≤10µs, duty cycle < 1%) are permitted per datasheet Section 4. Exceeding these limits risks permanent gate oxide damage, especially at elevated temperatures. A 15V nominal drive with clamping protection is standard practice.

Can IKW50N65H5AXKSA1 be used in parallel configurations?

Yes-its positive temperature coefficient of V_CE(sat) and tight V_GE(th) distribution (3.2–4.8V) enable stable current sharing. Successful paralleling requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling. Derating to 45A per device is recommended for 2-unit parallel operation at 100°C case temperature.

Is the RAPID 1 diode in this DuoPack optimized for reverse recovery or forward conduction?

The RAPID 1 diode is co-optimized for both: it achieves low forward voltage (1.50–1.54V) at 25A while maintaining soft, low-charge reverse recovery (Q_rr = 0.26–1.03µC). This dual optimization reduces conduction loss during freewheeling and minimizes voltage overshoot and EMI during turn-off transitions in hard-switched topologies.

Does this part require a negative gate voltage for reliable turn-off?

No-reliable turn-off is achieved with 0V gate drive due to its low leakage (I_CES = 40µA @ 175°C) and robust threshold margin. However, applying –5V to –10V improves noise immunity in high-dV/dt environments and accelerates turn-off, particularly in multi-kW systems with long gate traces or shared ground paths.
