Product details

Overview

AIKW20N60CTXKSA1 from Infineon is a 600 V, 20 A automotive-grade IGBT in a DuoPack configuration with integrated soft-recovery Emitter Controlled diode, featuring 1.5 V typical V_CE(sat) at 25°C, 175°C maximum junction temperature, and 5 µs short-circuit withstand time - deployed in main inverters and climate compressor drives for electric vehicles.

For engineers reviewing the AIKW20N60CTXKSA1 datasheet, AIKW20N60CTXKSA1 pinout, AIKW20N60CTXKSA1 application, or AIKW20N60CTXKSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (120 nC), tight parameter distribution from TRENCHSTOP™/Fieldstop technology, and thermal robustness up to 175°C junction operation.

Technical Context

This IGBT uses Infineon's TRENCHSTOP™ and Fieldstop technology optimized for 600 V automotive traction and auxiliary power conversion, delivering positive V_CE(sat) temperature coefficient and stable dynamic behavior across -40°C to +175°C. Its integrated Emitter Controlled diode provides soft, fast recovery (trr = 41 ns typ. at 25°C) with low Q_rr (0.31 µC) and controlled dirr/dt (-711 A/µs).

The device operates with ±20 V gate-emitter voltage rating and exhibits low switching losses (E_on = 0.31 mJ, E_off = 0.46 mJ at 25°C), enabled by low input capacitance (C_ies = 1100 pF) and optimized gate drive sensitivity (V_GE(th) = 4.1–5.7 V). It is dynamically stress tested and 100% short-circuit validated per AEC-Q101.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - supports DC-link voltages up to 400 V in automotive inverters with margin for transients.
I_C	20 A continuous - rated for sustained motor drive output at 100°C case temperature.
V_CE(sat)	1.5 V (typ. at 25°C) - enables high-efficiency conduction with low thermal dissipation in compact heatsinks.
t_SC	5 µs - allows robust fault handling in overcurrent events without desaturation circuitry overhead.
Q_G	120 nC - reduces gate driver power requirement and simplifies isolated gate drive design.
T_vj(max)	175°C - supports high-temperature under-hood operation without derating in PTC heater or compressor modules.
trr	41 ns (typ. at 25°C) - minimizes diode reverse recovery loss and EMI during hard-switching commutation.
R_th(j-c) (IGBT)	0.90 K/W - enables direct mounting to heatsink with predictable thermal interface performance.

Pinout & Package

AIKW20N60CTXKSA1 is housed in PG-TO247-3 package - a through-hole, single-island thermally optimized variant of TO-247 with 3 terminals: Gate (G), Collector (C), and Emitter (E). The package features insulated mounting hole, creepage/clearance compliant with automotive safety standards, and green (lead-free, halogen-free) construction.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	Accepts ±20 V logic-level drive; threshold voltage 4.1–5.7 V ensures noise immunity and clean turn-on at 15 V bias.
C	High-side collector node	Carries full load current and blocks 600 V; bonded directly to copper baseplate for minimal R_th(j-c).
E	Emitter common reference	Serves as return path for both IGBT and antiparallel diode; electrically isolated from heatsink mounting surface.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain use including temperature cycling, HTRB, and humidity testing per stress test plan.
Positive V_CE(sat) tempco	Enables inherent current sharing in parallel configurations without external ballasting resistors.
Soft, fast recovery diode	Emitter Controlled HE diode with 41 ns trr and low Irrm (13.3 A) reduces voltage overshoot and snubber burden.
Low EMI signature	Controlled di/dt and dv/dt due to optimized field-stop structure and low C_res (32 pF) minimize conducted emissions.
100% dynamic testing	Each unit verified for switching energy, V_CE(sat), and V_F at production test - no sampling-based validation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW20N60T	No AEC-Q101 qualification; identical electrical specs but industrial-grade screening and packaging.	Limited to non-safety-critical industrial motor drives; not approved for automotive powertrain or ADAS-related subsystems.	Select when cost sensitivity outweighs automotive compliance requirements and thermal environment remains <150°C.
AIKW40N60CT	40 A rated current; higher V_CE(sat) (1.6 V typ.) and Q_G (220 nC); same package and AEC-Q101 grade.	Supports higher-power inverters (e.g., dual-motor AWD systems); requires larger gate driver and heatsink footprint.	Choose for scalability where future power upgrade is anticipated, accepting 15% higher conduction loss at 20 A nominal load.

Compared with IKW20N60T and AIKW40N60CT, AIKW20N60CTXKSA1 uniquely balances automotive qualification, thermal headroom, and gate drive efficiency - making it optimal for space-constrained, safety-critical 20 A inverter stages where reliability and regulatory compliance are non-negotiable.

FAQ

What is the maximum allowable gate-emitter voltage for AIKW20N60CTXKSA1?

The absolute maximum gate-emitter voltage is ±20 V, as specified in the Maximum Ratings table. Operation beyond this range risks irreversible gate oxide damage. For reliable switching, Infineon recommends V_GE = +15 V for turn-on and –5 V to –10 V for active Miller clamping during turn-off to prevent false triggering.

Does AIKW20N60CTXKSA1 require an external freewheeling diode?

No - it integrates a soft, fast-recovery Emitter Controlled diode in a monolithic DuoPack configuration. This diode is co-packaged and electrically matched to the IGBT, eliminating layout parasitics and enabling optimized commutation without discrete diode placement or matching.

How does the 5 µs short-circuit withstand time translate to system-level protection design?

The 5 µs rating means the device can safely sustain a bolted short-circuit condition at V_CC ≤ 400 V and T_vj = 150°C before thermal runaway. System designers must implement desaturation detection with <3 µs response time and gate shutdown within 2 µs to remain within this limit - no external current-limiting hardware is needed.

Is the PG-TO247-3 package compatible with standard TO-247 heatsink mounts?

Yes - the PG-TO247-3 uses the industry-standard TO-247 mechanical outline with M3 mounting screw hole and 2.54 mm lead pitch. However, its insulated mounting surface and internal die layout differ from generic TO-247; thermal interface material must be applied only to the copper baseplate, not the plastic body.
