Product details

Overview

IKW50N120CH7XKSA1 from Infineon is a 1200 V, 50 A high-speed TRENCHSTOP™ IGBT 7 co-packed with a full-rated 50 A ultra-fast recovery diode in a PG-TO247-3-STD package. It delivers V_CE(sat) = 1.7 V at 25°C, t_off = 319 ns, and Q_rr = 1.48 µC, enabling high-efficiency hard-switching in industrial UPS, EV charging, and string inverters.

For engineers reviewing the IKW50N120CH7XKSA1 datasheet, IKW50N120CH7XKSA1 pinout, IKW50N120CH7XKSA1 application, or IKW50N120CH7XKSA1 equivalent, key selection criteria include its positive V_CE(sat) temperature coefficient for stable paralleling, soft-commutating diode behavior, and 175°C maximum junction temperature for demanding thermal environments.

Technical Context

This device implements Infineon's 7th-generation TRENCHSTOP™ IGBT process with optimized carrier lifetime control and emitter-controlled diode design. Its low Q_rr (1.48 µC) and soft reverse recovery (trr = 116 ns, dirr/dt = −383 A/µs) minimize voltage overshoot and EMI in high dv/dt topologies like 3-level NPC and T-type inverters.

The IGBT features a gate charge of 375 nC and total switching energy of 3.45 mJ at 25°C, balanced for high-frequency operation up to 30 kHz while maintaining low conduction loss. Thermal resistance R_th(j-c) is 0.29 K/W (IGBT) and 0.5 K/W (diode), supporting robust thermal management in compact power modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC bus voltages up to 1000 V in 2-level inverters and 600–800 V in 3-level topologies.
I_C	50 A continuous - rated for sustained output current in industrial UPS and solar string inverters.
V_CE(sat)	1.7 V @ 25°C - reduces conduction losses and improves system efficiency at nominal load.
t_off	319 ns @ 25°C - enables fast turn-off with minimal tail current, critical for high-frequency hard switching.
Q_rr	1.48 µC @ 25°C - lowers diode recovery loss and reduces snubber stress in inductive switching circuits.
T_vj(max)	175°C - allows operation in high-ambient environments without derating, extending reliability in sealed enclosures.
R_th(j-c) (IGBT)	0.29 K/W - enables efficient heat transfer to heatsink, supporting compact thermal design in space-constrained systems.

Emiter (E)	Common emitter/diode cathode node	Serves as reference for both IGBT and anti-parallel diode; must be low-inductance layout due to shared current path.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N120H3	1200 V, 40 A, TRENCHSTOP™ 3 generation; higher V_CE(sat) (2.1 V), slower t_off (450 ns), no soft diode.	Limited to ≤15 kHz switching; requires snubber for diode recovery; lower current handling.	Select only for cost-sensitive legacy designs where switching frequency and EMI are non-critical.
FF50R12ME4	1200 V, 50 A, EconoDUAL™ module with SiC diode; lower Q_rr (0.4 µC), but higher gate drive complexity and cost.	Better suited for >50 kHz operation and ultra-low-loss systems; not drop-in compatible due to module footprint and dual-source architecture.	Choose when system-level efficiency gain justifies redesign effort and higher BOM cost.

Compared with IKW40N120H3, IKW50N120CH7XKSA1 delivers 25% higher current rating, 30% faster turn-off, and integrated soft diode-enabling smaller magnetics and fewer passive components. Versus FF50R12ME4, it offers direct TO-247 compatibility and simpler gate drive, trading ~15% higher switching loss for ease of integration and lower system cost.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

The datasheet specifies RG(off) ≥ 8 Ω for safe SOA operation. Using RG = 8–15 Ω balances switching speed and voltage overshoot; values above 22 Ω increase t_off beyond 400 ns and raise E_off by >35%, risking thermal runaway under high-load conditions.

Can IKW50N120CH7XKSA1 replace older TRENCHSTOP™ 5 or 6 IGBTs in existing designs?

Yes, it is pin-compatible with IKW50N120H5 and IKW50N120H6 in PG-TO247-3-STD packages. However, gate charge is 12% higher than H6, requiring verification of driver capability and gate loop inductance to avoid oscillation.

Is the integrated diode rated for freewheeling in bidirectional topologies?

Yes-the co-packed diode is rated for 50 A continuous forward current and 200 A pulsed current, with soft recovery (I_rrm = 28 A, dirr/dt = −383 A/µs) validated for freewheeling in 2L and 3L inverter legs without external diodes.

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

No-turn-off is stable with 0 V gate bias. The datasheet confirms safe operation with V_GE = 0/15 V; applying −5 V offers marginal noise immunity but is unnecessary for standard industrial layouts with proper gate routing and decoupling.
