Product details

Overview

AIKW50N60CTXKSA1 from Infineon is an automotive-grade 600 V, 50 A TRENCHSTOP™ IGBT with integrated emitter-controlled diode in a PG-TO247-3 package. It delivers 1.5 V typical V_CE(sat) at 25°C, 175°C maximum junction temperature, and 5 µs short-circuit withstand time - enabling high-efficiency, rugged DC/AC inverters for electric vehicle powertrains.

For engineers reviewing the AIKW50N60CTXKSA1 datasheet, AIKW50N60CTXKSA1 pinout, AIKW50N60CTXKSA1 application, or AIKW50N60CTXKSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low EMI profile, soft fast-recovery diode behavior, positive V_CE(sat) temperature coefficient, and dynamic test validation across temperature and load conditions.

Technical Context

This IGBT uses TRENCHSTOP™ and Fieldstop technology optimized for 600 V automotive traction and auxiliary power conversion. Its integrated emitter-controlled diode features 143 ns typ. reverse recovery time (25°C) and 4.30 µC Q_rr (175°C), minimizing switching losses and voltage overshoot during commutation.

The device exhibits tightly distributed electrical parameters, stable thermal behavior up to 175°C, and gate charge of 310 nC - supporting precise PWM control in high-frequency inverter stages while maintaining robust short-circuit ruggedness under 400 V bus conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - supports 400 V DC-link systems with 50 % voltage margin for transient overvoltage handling
I_C	50 A continuous - rated for sustained motor phase current in 30–40 kW inverter modules
V_CE(sat)	1.5 V (typ., 25°C) - reduces conduction loss by ~30 % vs. standard 600 V IGBTs, improving system efficiency
t_SC	5 µs - enables reliable desaturation detection and fault shutdown in automotive safety-critical inverters
R_th(j-c) (IGBT)	0.45 K/W - allows 333 W power dissipation at 25°C case temperature, simplifying heatsink sizing
Q_G	310 nC - compatible with standard 15 V gate drivers; enables <350 ns total switching time with 7 Ω gate resistor
trr (diode)	143 ns (typ., 25°C) - ensures low diode recovery loss and reduced EMI in hard-switched PFC and inverter legs

Pinout & Package

PG-TO247-3 package: isolated metal tab, through-hole mounting, 0.6 Nm max screw torque, wave-solderable (260°C, 10 s). Thermal resistance R_th(j-c) = 0.45 K/W (IGBT), 0.80 K/W (diode).

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC-link positive; carries full phase current and must be routed with low-inductance layout
Gate (G)	Control input for IGBT channel	Requires low-impedance drive (RG = 7 Ω typical); sensitive to dv/dt-induced false turn-on without proper Miller clamp
Emiter (E)	Common emitter node for IGBT and antiparallel diode	Serves as power ground reference; critical for accurate current sensing and gate driver return path integrity

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain use including temperature cycling, HTRB, and humidity testing per JEDEC standards
Positive V_CE(sat) tempco	Enables inherent current sharing in parallel configurations without external ballasting resistors
Soft, fast-recovery diode	Emitter-controlled structure limits di/dt during reverse recovery, reducing voltage spikes and snubber requirements
100 % short-circuit tested	Each unit validated for 5 µs withstand at 150°C junction temperature - no screening escape risk in field operation
Low EMI design	Optimized internal layout and controlled switching transitions reduce radiated emissions in 150–300 MHz band

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW50N60T	No AEC-Q101 qualification; identical electrical specs but industrial-grade screening only	Not approved for ASIL-B/C automotive systems; suitable for industrial motor drives and UPS	Select when automotive qualification is not required and cost sensitivity outweighs functional safety compliance
AIKW40N60CT	Lower 40 A rating; same V_CE(sat), t_SC, and package; 20 % lower conduction loss at partial load	Better suited for 25–30 kW inverters where peak current rarely exceeds 40 A	Choose for thermally constrained designs where derating headroom and lower Q_G (270 nC) improve gate drive efficiency

Compared with IKW50N60T and AIKW40N60CT, AIKW50N60CTXKSA1 uniquely combines AEC-Q101 compliance, 50 A continuous rating, and integrated diode softness - making it the only option qualified for safety-critical main inverter use in production BEVs without design revalidation.

FAQ

What is the maximum allowable gate-emitter voltage for AIKW50N60CTXKSA1?

The absolute maximum gate-emitter voltage is ±20 V, with recommended operating range of –10 V to +15 V. Exceeding +15 V risks accelerated gate oxide degradation, while negative bias below –10 V may cause unintended turn-off due to Miller-induced voltage spikes during high dv/dt switching events.

Does AIKW50N60CTXKSA1 require a negative gate drive voltage?

No, it does not require negative gate drive. The device is fully functional with 0 V / +15 V gate drive, but a –5 V to –10 V negative bias improves noise immunity and prevents false turn-on during high-speed switching in noisy automotive environments, especially in parallel configurations.

How is the "DuoPack" configuration implemented internally?

The DuoPack integrates one TRENCHSTOP™ IGBT and one emitter-controlled diode in a single PG-TO247-3 package with shared emitter terminal. The diode is co-packaged but electrically independent - no monolithic integration - enabling optimized die sizing and thermal coupling while retaining separate device characterization.

Can AIKW50N60CTXKSA1 replace older AIKW50N60CT variants?

Yes - AIKW50N60CTXKSA1 is a direct replacement for AIKW50N60CT with identical pinout, ratings, and performance. The "XKSA1" suffix denotes Infineon's standardized automotive packaging and traceability format (including lot-level AEC-Q101 test records), with no electrical or thermal differences from prior revisions.
