Product details

Overview

AIKQ120N60CTXKSA1 from Infineon is a 600 V, 120 A automotive-grade TRENCHSTOP™ IGBT with integrated Emitter Controlled diode in PG-TO247-3-46 package, featuring 1.5 V typical V_CE(sat) at 25°C, 5 µs short-circuit withstand time, and 175°C maximum junction temperature - deployed in main inverters for electric powertrains.

For engineers reviewing the AIKQ120N60CTXKSA1 datasheet, AIKQ120N60CTXKSA1 pinout, AIKQ120N60CTXKSA1 application, or AIKQ120N60CTXKSA1 equivalent, key selection criteria include V_CE(sat) temperature stability, soft fast-recovery diode performance, short-circuit ruggedness, and AEC-Q101 qualification for traction inverters.

Technical Context

This IGBT uses TRENCHSTOP™ and Fieldstop technology optimized for 600 V DC/AC converters, delivering tight parameter distribution and high thermal ruggedness up to 175°C junction temperature. Its positive V_CE(sat) temperature coefficient enables inherent current sharing in parallel configurations.

The integrated Emitter Controlled diode provides very soft, fast recovery (280 ns trr at 25°C, 410 ns at 175°C) with low Q_rr (3.5 µC typ. at 25°C), minimizing switching losses and EMI in hard-switched inverter topologies.

V_CE	600 V - supports 400 V DC-link systems with 50 % voltage margin for transient overvoltage handling
I_C	120 A continuous - rated for sustained motor phase current in 45–60 kW traction inverters
V_CE(sat)	1.5 V (typ., 25°C) - reduces conduction loss by ~25 % vs. standard 600 V IGBTs at same current
t_SC	5 µs - enables robust protection coordination with gate driver desaturation detection
Q_G	772 nC - allows efficient gate driving with moderate 3 Ω external resistance at 15 V
trr / Q_rr	280 ns / 3.5 µC (25°C) - limits diode reverse recovery stress and snubber requirements
R_th(j-c)	0.18 K/W (IGBT), 0.30 K/W (diode) - enables high-power density thermal design with direct heatsink mounting

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW120N60T7	650 V rating, lower V_CE(sat) (1.35 V), higher Q_G (920 nC), same PG-TO247-3-46 package	Better for 450–500 V DC-link systems; requires stronger gate driver due to higher Q_G	Select when higher voltage margin and lower conduction loss outweigh gate drive complexity
AIKQ120N60CTH	Same die, halogen-free variant with identical electrical specs and AEC-Q101 qualification	No functional difference; differs only in material compliance documentation	Select when full IEC 61249-2-21 halogen-free certification is required for Tier 1 submission

Compared with IKW120N60T7 and AIKQ120N60CTH, AIKQ120N60CTXKSA1 offers optimal balance of 600 V rating, proven 5 µs short-circuit ruggedness, and gate drive simplicity - making it preferred for cost-sensitive, high-volume traction inverter designs where 400 V DC-link stability is assured.

FAQ

What is the maximum allowable gate-emitter voltage for AIKQ120N60CTXKSA1?

The absolute maximum gate-emitter voltage is ±20 V, with recommended operating range of –10 V to +15 V. Exceeding +15 V increases risk of gate oxide degradation, while negative bias below –10 V may cause unintended turn-on due to Miller coupling during high dv/dt events. Gate drive circuits must include clamping and negative turn-off capability.

Does AIKQ120N60CTXKSA1 require an external freewheeling diode?

No - it integrates a soft, fast-recovery Emitter Controlled diode rated for 120 A continuous and 480 A pulsed forward current. This diode exhibits 280 ns reverse recovery time and 3.5 µC recovery charge at 25°C, eliminating need for discrete antiparallel diodes in standard inverter leg configurations.

How is short-circuit protection implemented with this IGBT?

AIKQ120N60CTXKSA1 supports desaturation-based protection with 5 µs short-circuit withstand time at V_GE = 15 V and V_CC ≤ 400 V. Protection circuits must detect V_CE rise above 5 V within 2–3 µs and initiate gate turn-off within ≤2 µs to avoid thermal runaway. Each unit is 100 % factory-tested for this capability.

Can AIKQ120N60CTXKSA1 be paralleled for higher current capacity?

Yes - its positive V_CE(sat) temperature coefficient ensures inherent current sharing across parallel devices. Successful paralleling requires matched gate drive impedance (<±5 %), symmetrical PCB layout, and shared heatsink mounting to maintain ΔT_j < 5°C. Derating to 85 % of total rated current is recommended for long-term reliability.
