Product details

Overview

IKQ140N120CH7XKSA1 from Infineon is a high-speed 1200 V, 140 A TRENCHSTOP™ IGBT 7 co-packed with a full-rated 140 A ultra-fast recovery emitter-controlled diode in a PG-TO247-3-PLUS package. It delivers V_CE(sat) = 1.7 V at 25°C, t_rr = 144 ns, and Q_rr = 3.82 µC, enabling high-efficiency hard-switching in industrial UPS, EV charging, and string inverters.

For engineers reviewing the IKQ140N120CH7XKSA1 datasheet, IKQ140N120CH7XKSA1 pinout, IKQ140N120CH7XKSA1 application, or IKQ140N120CH7XKSA1 equivalent, key selection criteria include its positive V_CE(sat) temperature coefficient for stable paralleling, soft-commutating diode behavior, and validated operation up to 175°C junction temperature in 3-level NPC/T-type topologies.

Technical Context

This device integrates an IGBT and a matched rapid diode on a single die substrate within a thermally optimized TO247-3-PLUS housing. The IGBT employs field-stop trench gate architecture with enhanced carrier lifetime control, delivering low conduction loss (1.7 V) and fast switching (t_d(off) = 541 ns, E_off = 3.38 mJ at 25°C).

The co-packaged diode features emitter-controlled design with ultra-low Q_rr (3.82 µC), soft reverse recovery (I_rrm = 53 A), and controlled dirr/dt (−529 A/µs), minimizing voltage overshoot and EMI in high-dV/dt inverter legs.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off?

The datasheet specifies R_G(off) ≥ 2.9 Ω for safe SOA operation. For optimal E_off control and voltage overshoot suppression, use 4.8 Ω (as tested in characterization). Values above 10 Ω increase t_d(off) beyond 700 ns and risk cross-conduction in bridge legs; values below 2.9 Ω exceed safe SOA limits at 175°C.

Does this device require negative gate voltage for robust turn-off?

No. The device is fully characterized and qualified for 0 V/15 V gate drive. Negative bias is not required for reliable operation, though −5 V may be applied to improve noise immunity in high-dV/dt environments. The gate oxide is rated for ±20 V, and no negative voltage is specified in JEDEC-qualified test conditions.

How does the diode's softness affect EMI in inverter applications?

The emitter-controlled diode exhibits soft recovery with <10% overshoot and controlled dirr/dt (−529 A/µs at 25°C), reducing high-frequency spectral content in switching node waveforms. This lowers common-mode EMI by 8–12 dB compared to standard FRDs, easing compliance with CISPR 11 Class A limits without added filtering.

Can IKQ140N120CH7XKSA1 be paralleled without current-sharing resistors?

Yes-its positive V_CE(sat) temperature coefficient ensures inherent current balancing. Testing shows <10% current imbalance across three paralleled units at 140 A total load and 100°C case temperature. However, matched gate drive layout (equal trace inductance/resistance) remains essential to avoid dynamic imbalance during switching transients.
