Product details

Overview

IKZA40N120CS7XKSA1 from Infineon is a short-circuit rugged 1200 V, 40 A TRENCHSTOP™ IGBT 7 co-packed with a full-current soft-recovery Emitter Controlled 7 diode in PG-TO247-4-STD-NT3.7 package; features V_CE(sat) = 2.0 V at T_vj = 175°C, 8 µs short-circuit withstand time, and optimized hard-switching performance for 2-level inverters and 3-level NPC/T-type topologies in industrial power conversion.

For engineers reviewing the IKZA40N120CS7XKSA1 datasheet, IKZA40N120CS7XKSA1 pinout, IKZA40N120CS7XKSA1 application, or IKZA40N120CS7XKSA1 equivalent, key selection criteria include 1200 V blocking voltage, 40 A rated current, co-packaged diode Q_rr and softness, thermal resistance R_th(j-c) = 0.42 K/W (IGBT), and gate charge Q_G = 230 nC for gate driver sizing.

Technical Context

This IGBT employs TRENCHSTOP™ 7 silicon technology with field-stop and trench-gate structures to achieve low conduction loss and controlled switching behavior. Its co-packaged Emitter Controlled 7 diode delivers low Q_rr (2.5 µC typ. at 25°C) and soft reverse recovery (trr = 110 ns typ.), minimizing voltage overshoot and EMI in high-dv/dt inverter legs.

The device is rated for 1200 V DC collector-emitter voltage and supports hard-switching operation up to 175°C junction temperature, with validated short-circuit ruggedness of 8 µs under V_CC ≤ 600 V and V_GE = 15 V - enabling robust protection in motor drive and solar inverter fault conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - enables use in 1000 V DC-link industrial and solar applications without derating.
I_C	40 A - continuous current rating at T_c = 100°C, suitable for 15–25 kW inverter stages.
V_CE(sat)	2.0 V at T_vj = 175°C - low conduction loss improves efficiency and reduces heatsink requirements.
t_SC	8 µs - verified short-circuit withstand time allows reliable overcurrent protection with fast desat detection.
Q_G	230 nC - determines gate driver peak current requirement (~57.5 A for 4 Ω turn-on resistor).
R_th(j-c) (IGBT)	0.42 K/W - enables thermal design with direct case mounting and moderate heatsink interface resistance.
trr / Q_rr	110 ns / 2.5 µC at 25°C - soft, low-charge diode recovery reduces snubber stress and EMI filtering burden.

Pinout & Package

Package: PG-TO247-4-STD-NT3.7 - 4-pin through-hole package with isolated emitter (E2) for Kelvin sensing, supporting low-inductance gate drive and accurate V_CE monitoring.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	High-side switch node connection; carries full load current and handles 1200 V blocking.
Gate (G)	Control input	Drives IGBT channel; requires <±20 V rating and low-impedance gate loop for stable switching.
Emitter (E1)	Main emitter return path	Carries full load current; connects to DC-link negative or phase-leg midpoint in 3L topologies.
Emitter (E2)	Kelvin emitter sense	Provides isolated reference for gate driver feedback and precise V_CE desat detection, reducing parasitic inductance impact.

Key Features

Feature	Design Value
Co-packaged EC7 diode	Full-rated 40 A soft-recovery diode with 2.5 µC Q_rr, eliminating need for external anti-parallel diode and reducing layout complexity.
Short-circuit ruggedness	8 µs withstand time at 150°C junction temperature enables deterministic fault handling without latch-up in industrial drives.
dv/dt controllability	Wide operating range supports stable switching across 5–50 V/ns, easing EMI compliance in variable-speed drives.
TRENCHSTOP™ 7 process	Optimized trade-off between V_CE(sat) and switching losses yields 3.01 mJ total switching energy at 25°C for 600 V/40 A conditions.
Thermal performance	R_th(j-c) = 0.42 K/W (IGBT) and 0.75 K/W (diode) allow parallel operation with matched thermal impedance in multi-phase systems.

Use Scenario: DC–AC conversion stage in string inverters with 1000 V nominal DC input and grid-tied AC output.

IC Role / Device Role / Timing Role: High-side IGBT in NPC or T-type topology; switches at 16–20 kHz with co-packaged diode managing freewheeling current.

Use Value: Low Q_rr and soft recovery reduce diode-induced voltage spikes and snubber losses, improving system efficiency >98.5%.

Industrial UPS Systems

Energy Storage Inverters

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N120H3	1200 V, 40 A TRENCHSTOP™ 3 IGBT; no co-packaged diode; higher V_CE(sat) = 2.2 V at 175°C; 6 µs SC rating.	Requires external diode; less suited for space-constrained designs needing integrated diode softness.	Select when cost sensitivity outweighs diode integration benefit and thermal margin permits higher V_CE(sat).
FF400R12ME4	1200 V, 400 A module with built-in NTC and press-fit terminals; includes anti-parallel diodes but larger footprint and higher gate charge (Q_G ≈ 1200 nC).	Targeted at high-power (>100 kW) systems; not drop-in compatible due to package, pinout, and drive requirements.	Choose for scalable multi-kW platforms where module-level integration and thermal management supersede discrete flexibility.

Compared with IKW40N120H3 and FF400R12ME4, IKZA40N120CS7XKSA1 uniquely combines discrete-level design freedom, integrated soft diode, and 8 µs short-circuit ruggedness - making it optimal for compact, high-reliability 15–30 kW industrial inverters requiring minimal external components and precise fault control.

FAQ

What is the purpose of the 4th pin (E2) on the IKZA40N120CS7XKSA1?

The E2 pin is a Kelvin emitter terminal isolated from the main emitter (E1). It provides a dedicated low-inductance path for gate driver feedback and V_CE desaturation detection, enabling accurate real-time monitoring of IGBT saturation voltage without interference from power loop voltage drops.

Can IKZA40N120CS7XKSA1 be used in 3-level T-type inverters?

Yes - its 1200 V blocking voltage, 40 A current rating, and co-packaged soft diode make it suitable for high-side and low-side positions in 3-level T-type inverters. The device's 8 µs short-circuit rating and dv/dt controllability support safe operation during shoot-through fault conditions common in T-type topologies.

How does the Emitter Controlled 7 diode differ from standard FRD diodes?

The EC7 diode features tailored carrier lifetime control and optimized doping profiles to deliver lower Q_rr (2.5 µC vs. >4 µC typical for FRDs), reduced peak reverse recovery current (I_rrm = 63 A), and soft recovery (no current snap-off), minimizing voltage overshoot and EMI generation during commutation in high-frequency inverters.

Is thermal derating required when operating above 100°C case temperature?

Yes - the datasheet specifies I_C = 40 A at T_c = 100°C and I_C = 82 A at T_c = 25°C. Operation above 100°C requires linear derating per the R_th(j-c) = 0.42 K/W curve; junction temperature must remain ≤175°C, and Infineon recommends staying below 80% of max ratings for long-term reliability.
