Product details

Overview

IKFW50N65DH5XKSA1 from Infineon is a 650 V, 50 A TRENCHSTOP™ 5 Advanced Isolation IGBT with integrated RAPID 1 antiparallel diode in a fully isolated TO-247 package. It delivers 1.8 V V_CE(sat) at 50 A and 25°C, supports 175°C maximum junction temperature, and provides 2500 V_RMS isolation for high-reliability industrial switching in PFC and welding converters.

For engineers reviewing the IKFW50N65DH5XKSA1 datasheet, IKFW50N65DH5XKSA1 pinout, IKFW50N65DH5XKSA1 application, or IKFW50N65DH5XKSA1 equivalent, this device is selected for hard-switching efficiency, soft diode recovery in bidirectional current paths, and thermal robustness in isolated heatsink mounting configurations.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop technology to achieve low conduction loss (1.8 V V_CE(sat)) and low gate charge (95 nC), enabling high-efficiency operation up to mid-range switching frequencies. Its co-packed RAPID 1 diode exhibits 68 ns trr and 0.55 µC Q_rr at 25°C, ensuring minimal reverse recovery stress during commutation.

The device integrates full electrical isolation (2500 V_RMS, 1 min) between collector and mounting surface, verified by 100% production testing. Thermal resistance from junction to heatsink is 1.03–1.21 K/W, optimized for forced-air or liquid-cooled industrial inverters where thermal interface reliability is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE Rating	650 V - Supports DC bus voltages up to 400 V in three-phase rectified systems with margin for transients.
I_C Continuous	50 A at T_h = 25°C - Sustains rated output current in PFC stages without derating under standard heatsink conditions.
V_CE(sat)	1.8 V at I_C = 50 A, T_vj = 25°C - Enables <1.5 W conduction loss per device at full load, reducing thermal design burden.
Q_G	95 nC - Allows gate drive with moderate-current ICs (e.g., 2–4 A peak) while maintaining fast turn-on/turn-off control.
trr / Q_rr	68 ns / 0.55 µC at 25°C - Limits diode-induced voltage overshoot and EMI in hard-switched bridge legs.
T_vj(max)	175°C - Permits operation in high-ambient environments (e.g., enclosed welders) with extended lifetime at elevated junction temperatures.
R_th(j-h)	1.03–1.21 K/W - Enables direct mounting to insulated heatsinks without thermal paste degradation concerns in long-life industrial systems.

Pinout & Package

Package: PG-HSIP247-3-2 (TO-247 variant with isolated mounting base). The device uses a 3-pin configuration with electrically isolated collector tab for direct heatsink attachment.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal, electrically isolated from mounting surface	Enables floating collector connection in half-bridge topologies; isolation allows direct bolt-down to grounded heatsink without insulating hardware.
Gate (G)	Control input for IGBT channel	Receives 15 V logic-level drive; low 95 nC Q_G reduces gate driver power and layout sensitivity to parasitic inductance.
Emiter (E)	Power return path and reference for gate drive	Serves as common emitter node for both IGBT and antiparallel diode; must be referenced to driver ground for stable switching behavior.

Key Features

Feature	Design Value
TRENCHSTOP™ 5 IGBT die	Reduces conduction + switching losses simultaneously vs. prior generations-enabling >98% efficiency in 16–30 kHz PFC designs.
RAPID 1 antiparallel diode	Soft reverse recovery (12 A I_rrm, −834 A/µs dirr/dt) minimizes snubber requirements and dv/dt-induced shoot-through risk.
2500 V_RMS isolation	Eliminates need for insulating pads or shoulder washers in TO-247 mounting-reducing thermal resistance and assembly steps.
100% isolated surface test	Guarantees dielectric integrity across production lot-critical for safety-critical industrial equipment requiring UL/IEC certification.
Pb-free, RoHS-compliant plating	Meets global environmental compliance mandates without sacrificing solderability or long-term intermetallic stability.

Applications

Residential Air Conditioner PFC Stage

Industrial Welding Inverter

Use Scenario: Boost converter operating at 20–30 kHz to correct AC line input power factor in 3–5 kW HVAC units.

IC Role / Device Role / Timing Role: High-side switch in interleaved boost topology; handles continuous 50 A RMS current with peak 160 A pulsed capability.

Use Value: Low V_CE(sat) and soft diode recovery reduce heatsink size by ~30% versus legacy 650 V IGBTs, enabling compact outdoor unit designs.

Use Scenario: Primary-side H-bridge in 10–20 kHz inverter-based arc welders delivering 200–300 A output current.

IC Role / Device Role / Timing Role: Main switching element in full-bridge configuration; operates with 131 ns t_d(off) and 20 ns t_f at 150°C junction.

Use Value: 175°C T_vj(max) and isolated package allow sustained duty cycles without thermal shutdown, improving weld consistency and uptime.

Mid-Frequency UPS Inverter

Motor Drive Intermediate Bus Converter

Use Scenario: DC-AC inverter stage in 5–10 kVA online UPS systems switching at 12–16 kHz with sinusoidal PWM.

IC Role / Device Role / Timing Role: Leg switch in three-phase inverter; conducts bidirectional current via integrated RAPID 1 diode during freewheeling.

Use Value: 0.55 µC Q_rr and 68 ns trr suppress diode-induced voltage spikes, reducing filter capacitor stress and audible noise.

Use Scenario: Isolated DC-DC stage converting 600 V DC bus to 48 V for control electronics in servo drives and PLC power supplies.

IC Role / Device Role / Timing Role: Primary-side switch in phase-shifted full-bridge topology; benefits from low Q_G for precise dead-time control.

Use Value: 95 nC gate charge enables use of cost-effective 2 A gate drivers while maintaining <20 ns rise/fall time margin at full load.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW50N65ES5	No integrated isolation; standard TO-247 package requires external insulator; higher R_th(j-h) (1.4 K/W typical).	Suitable only when heatsink isolation is implemented externally; not certified for direct-mount safety-critical use.	Select when cost sensitivity outweighs assembly simplification and safety certification needs.
FGH50T65SHD	Higher V_CE(sat) (2.0 V); lower Q_G (72 nC); no integrated diode-requires discrete antiparallel diode.	Requires additional diode selection, layout space, and thermal management for diode; better for ultra-high-frequency resonant topologies.	Select when system-level optimization favors separate diode tuning and gate drive simplicity over integration.

Compared with IKW50N65ES5 and FGH50T65SHD, IKFW50N65DH5XKSA1 uniquely combines certified isolation, integrated soft diode, and industry-leading conduction efficiency-making it optimal for space-constrained, safety-certified industrial converters where BOM count and thermal reliability are prioritized.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off at 150°C junction temperature?

Based on datasheet Figure 9, RG ≤ 25 Ω maintains td(off) < 180 ns and tf < 25 ns at Tvj = 150°C. Using RG = 12.2 Ω (as tested) ensures consistent turn-off timing and limits Eoff to 0.71 mJ. Higher values increase switching loss and risk incomplete turn-off under high di/dt conditions.

Can IKFW50N65DH5XKSA1 be used in parallel configurations?

Yes-its positive VCE(sat) temperature coefficient (1.8 V at 25°C → 2.25 V at 175°C) enables natural current sharing. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and identical thermal mounting to avoid thermal runaway; Infineon recommends ≤ 2 devices in parallel without active current balancing.

Does the 2500 VRMS isolation rating apply to the entire device lifetime?

Yes-the isolation is guaranteed for the full operational lifetime under JEDEC JESD22-A108 stress conditions. The 2500 VRMS rating is validated per IEC 60747-5-2 and includes 100% production testing of the isolated mounting surface, ensuring compliance in UL 62368-1 and IEC 61800-5-1 safety-critical systems.

Is the RAPID 1 diode rated for continuous reverse conduction?

No-the antiparallel diode is optimized for freewheeling and reverse recovery, not sustained reverse-biased operation. Its IF rating (40 A at Th = 25°C) applies only during forward conduction. Reverse voltage must remain within VRRM ≤ 650 V, and reverse conduction time must be limited by circuit topology to avoid thermal overstress.
