Product details

Overview

IHW15N120R3FKSA1 from Infineon is a reverse-conducting IGBT (RC-IGBT) with monolithic body diode, designed for resonant and soft-switching topologies in high-voltage power conversion. It features 1200 V V_CE, 15 A rated collector current, 1.48 V V_CEsat at 25°C, 175°C maximum junction temperature, and PG-TO247-3 package.

For engineers reviewing the IHW15N120R3FKSA1 datasheet, IHW15N120R3FKSA1 pinout, IHW15N120R3FKSA1 application, or IHW15N120R3FKSA1 equivalent, key selection criteria include its low switching losses in ZVS/ZCS circuits, tight parameter distribution from TRENCHSTOP™ technology, and integrated diode optimized for soft commutation-not hard-switched freewheeling.

Technical Context

This RC-IGBT integrates an anti-parallel diode on the same die, eliminating external diode placement and reducing parasitic inductance in resonant tank circuits. Its positive temperature coefficient of V_CEsat enables stable parallel operation without current-sharing resistors.

The device targets high-frequency resonant converters operating up to ~100 kHz, where low E_off (0.70 mJ at 25°C), fast fall time (46 ns), and controlled tail current minimize conduction and switching loss trade-offs under soft-commutation conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC bus voltages up to 800 V in 3-phase rectified systems with margin
I_C (rated)	15 A - continuous conduction capability at T_c = 100°C, suitable for 1–2 kW resonant inverters
V_CEsat	1.48 V @ 25°C - low conduction loss enabling high efficiency in medium-power ZVS applications
E_off	0.70 mJ @ 25°C - reduced turn-off energy critical for minimizing losses in high-frequency resonant switching
R_th(j-c)	0.59 K/W - enables direct heatsink mounting with predictable thermal performance in compact designs
f_sw max	~100 kHz - supported by low C_ies (1165 pF), C_res (32 pF), and fast switching times
T_vjmax	175°C - allows sustained operation under transient overloads in induction heating and microwave inverters

Pinout & Package

Supplied in PG-TO247-3 package with isolated mounting hole, standard leadframe layout, and creepage/clearance compliant with IEC 61800-5-1 for 1200 V systems.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Connected to DC+ rail; carries full load current and withstands 1200 V blocking
Gate (G)	Control input	Receives 15 V drive signal; requires gate resistor (14.6 Ω typical) for controlled dV/dt and EMI management
Emitter (E)	Power return and reference node	Serves as common source for IGBT and integrated diode; must be low-inductance connection to minimize voltage spikes

Key Features

Feature	Design Value
Monolithic body diode	Low V_F (1.55 V @ 25°C) and soft recovery tailored for zero-current switching-no external diode needed
TRENCHSTOP™ technology	Tight V_CEsat distribution (±0.1 V) and rugged short-circuit withstand (10 µs @ 175°C) improve system reliability
Positive V_CEsat tempco	Enables natural current sharing in paralleled configurations without external balancing components
JEDEC-qualified	Validated for industrial inverter applications per JESD47 stress testing-supports long-term field deployment

Applications

Induction Cooking Systems

Use Scenario: Resonant inverter powering magnetron with variable power control via frequency modulation.

IC Role / Device Role / Timing Role: High-voltage switch in asymmetrical half-bridge; operates with phase-shifted gate drive to achieve ZVS across wide load range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar reverse-conducting IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW15N120H3	Same 1200 V/15 A rating but uses H3 technology; lower V_CEsat (1.35 V) and higher C_res (42 pF)	Better conduction loss, slightly slower turn-off; suited for lower-frequency (<50 kHz) hard-switched PFC stages	Select when priority is lowest conduction loss over switching speed in fixed-frequency topologies
IRGP4062DPBF	1200 V/16 A standard IGBT + separate ultrafast diode; higher V_CEsat (1.8 V), no monolithic integration	Requires external diode layout; higher layout complexity and parasitic inductance in resonant tanks	Choose only if existing design uses discrete diode layout and cannot accommodate RC-IGBT footprint

Compared with IKW15N120H3 and IRGP4062DPBF, IHW15N120R3FKSA1 delivers superior soft-switching performance due to its monolithic diode's matched thermal and dynamic characteristics, lower E_off, and optimized capacitance profile for resonant operation-making it the preferred choice for ZVS/ZCS inverters above 30 kHz.

FAQ

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

A 14.6 Ω gate resistor is specified in the datasheet for standardized switching characterization (E_off, t_d(off)). Using >22 Ω increases turn-off delay and E_off significantly-especially at 175°C-risking shoot-through in bridge configurations. For ZVS applications, 10–15 Ω balances dV/dt control and loss minimization.

Can IHW15N120R3FKSA1 replace a standard IGBT + external diode in an existing design?

Yes, but only if the PCB layout accommodates the PG-TO247-3 footprint and the gate drive circuit accounts for the integrated diode's forward voltage and recovery behavior. The monolithic diode eliminates external diode selection but requires verification of dead-time settings to avoid cross-conduction during soft-commutation transitions.

Is this device suitable for hard-switched applications like motor drives?

No-it is not optimized for hard-switching. Its monolithic diode has soft recovery but higher V_F than dedicated ultrafast diodes, and its E_off rises sharply at high T_vj. In hard-switched motor drives, standard IGBTs like IKW40N120H3 offer better overall efficiency and ruggedness under short-circuit conditions.

Does the "R3" suffix indicate RoHS compliance and lead-free plating?

Yes-the "R3" suffix denotes Infineon's RoHS-compliant, lead-free lead plating per JEDEC J-STD-609. The device meets EU RoHS Directive 2011/65/EU and is compatible with standard SnAgCu reflow profiles (peak 260°C, 10 s).
