Product details

Overview

IKY140N120CH7XKSA1 from Infineon is a high-speed 1200 V TRENCHSTOP™ IGBT 7 co-packed with a full-rated 140 A ultra-fast recovery diode in a PG-TO247-4-PLUS package. It delivers V_CE(sat) = 1.7 V at 25°C, t_r = 20 ns, and Q_rr = 4.14 µC, enabling high-efficiency hard-switching in 2-level inverters and 3-level NPC/T-type topologies for industrial UPS and EV-charging systems.

For engineers reviewing the IKY140N120CH7XKSA1 datasheet, IKY140N120CH7XKSA1 pinout, IKY140N120CH7XKSA1 application, or IKY140N120CH7XKSA1 equivalent, key selection criteria include its positive V_CE(sat) temperature coefficient for stable paralleling, soft-commutating diode behavior, low E_off (3.9 mJ at 25°C), and JEDEC-qualified industrial reliability up to 175°C junction temperature.

Technical Context

This device integrates an IGBT and emitter-controlled 7 Rapid diode on a single die with shared thermal path and optimized layout for minimal parasitic inductance (L_E = 13 nH). Its gate charge (Q_G = 1032 nC) and transconductance (g_fs = 344 S) are tuned for fast, controllable switching under high dV/dt conditions.

The IGBT exhibits a well-defined turn-off safe operating area up to 1200 V with V_GE = 0/15 V and R_G(off) ≥ 8.2 Ω, while the diode achieves t_rr = 101 ns and dirr/dt = –3140 A/µs at 25°C - critical for minimizing voltage overshoot and EMI in high-frequency inverter legs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC-link voltages up to 960 V in 2L inverters with 25% safety margin

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed 1200 V IGBT + diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N120H3	1200 V, 40 A, TO247-3 package, no Kelvin emitter, higher V_CE(sat) (2.1 V), slower t_f (120 ns)	Limited to lower-power (<10 kW) designs; lacks soft diode and paralleling capability	Select when cost sensitivity outweighs efficiency and scalability needs in sub-50 A systems
FF140R12ME4	1200 V, 140 A, 62 mm module, dual IGBT+diode, higher thermal mass, R_th(j-c) = 0.18 K/W	Better suited for multi-kW modular inverters requiring standardized footprint and press-fit mounting	Choose for scalable system integration where board-level assembly and thermal management favor module form factor

Compared with IKW40N120H3 and FF140R12ME4, IKY140N120CH7XKSA1 uniquely combines discrete-level flexibility, Kelvin-emitter precision, and diode softness-making it optimal for high-density, high-frequency, and paralleled 10–100 kW inverter designs where layout control and dynamic loss minimization are critical.

FAQ

What is the purpose of the Kelvin emitter pin?

The Kelvin emitter (K) provides a dedicated low-inductance sense path for gate drive feedback, decoupling gate loop dynamics from main current flow. This ensures precise V_GE control during high-di/dt switching, preventing false turn-on and improving noise immunity-critical for stable operation above 20 kHz.

Can IKY140N120CH7XKSA1 be used in 3-level T-type inverters?

Yes. Its 1200 V V_CE, low Q_rr, and soft diode recovery make it suitable for both outer and inner switches in 3-level T-type topologies. The 175°C T_vj(max) and positive V_CE(sat) coefficient support balanced current sharing across paralleled devices in high-power legs.

How does the 7 Rapid diode differ from standard FRDs?

The 7 Rapid diode features emitter-controlled structure and tailored lifetime control, achieving lower Q_rr (4.14 µC), softer reverse recovery (reduced Irrm and E_rec), and higher dirr/dt tolerance (–3140 A/µs) than conventional fast recovery diodes-minimizing voltage spikes and EMI in high-dV/dt environments.

Is PSpice modeling supported for this device?

Yes. Infineon provides validated PSpice models for IKY140N120CH7XKSA1 covering both IGBT and diode characteristics-including temperature-dependent V_CE(sat), Q_G, t_r/t_f, VF, and Q_rr. These models are accessible via Infineon's official product page and support accurate loss and thermal simulation.
