Product details

Overview

IGW50N60H3FKSA1 from Infineon is a 600 V, 50 A high-speed trench and fieldstop IGBT with 1.85 V V_CE(sat) at T_vj = 25°C, rated for 175°C maximum junction temperature, and housed in PG-TO247-3 package. It delivers low EMI, soft fast-recovery anti-parallel diode behavior, and robust short-circuit withstand (5 µs at 150°C), targeting high-frequency industrial power converters.

For engineers reviewing the IGW50N60H3FKSA1 datasheet, IGW50N60H3FKSA1 pinout, IGW50N60H3FKSA1 application, or IGW50N60H3FKSA1 equivalent, key selection criteria include switching energy (E_on = 1.45 mJ, E_off = 0.91 mJ at 25°C), thermal resistance (R_th(j–c) = 0.45 K/W), gate charge (Q_G = 315 nC), and safe operating area up to 200 A pulsed current.

Technical Context

This third-generation High Speed Switching Series IGBT uses TRENCHSTOP™ technology to simultaneously minimize conduction loss (V_CE(sat) = 1.85 V @ 50 A) and switching loss (E_ts = 2.36 mJ @ 25°C). Its integrated anti-parallel diode features very soft reverse recovery, reducing voltage overshoot and system-level EMI.

The device supports operation up to 175°C junction temperature and is qualified per JEDEC standards for industrial applications. Gate threshold voltage (V_GE(th) = 4.1–5.7 V) and transconductance (g_fs = 30 S) are tightly specified to ensure stable drive and predictable current gain across temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	600 V - Maximum blocking voltage for DC-link applications up to 400 V bus with safety margin.
I_C	50 A continuous - Rated collector current at T_C = 100°C, enabling compact heatsink design in high-power converters.
V_CE(sat)	1.85 V @ T_vj = 25°C - Low conduction loss directly reduces power dissipation and improves efficiency at rated load.
E_off	0.91 mJ @ 25°C - Low turn-off energy enables higher switching frequencies without excessive thermal stress.
R_th(j–c)	0.45 K/W - Enables efficient heat transfer to heatsink; supports >330 W power dissipation at T_C = 25°C.
t_SC	5 µs @ V_GE = 15 V - Short-circuit ruggedness allows reliable fault handling in UPS and welding inverters.
Q_G	315 nC - Gate charge value informs driver sizing; compatible with standard ±15 V gate drivers delivering ≥2 A peak.

Pinout & Package

IGW50N60H3FKSA1 is housed in PG-TO247-3 package: insulated plastic case with 3 leads, 4.5 mm lead pitch, and screw-mount flange for mechanical stability and thermal interface.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to DC-link positive; carries full load current and must be routed with low-inductance layout.
Gate (G)	Control input	High-impedance MOS-controlled terminal requiring low-inductance gate loop and 7 Ω external resistor for optimized switching.
Emiter (E)	Power return and reference node	Serves as common emitter for IGBT and anti-parallel diode; critical for stable gate drive referencing and noise immunity.

Key Features

Feature	Design Value
TRENCHSTOP™ technology	Enables simultaneous low V_CE(sat) (1.85 V) and low switching losses (E_ts = 2.36 mJ), improving system efficiency at 10–50 kHz.
Soft, fast-recovery anti-parallel diode	Reduces voltage overshoot during commutation, lowering snubber requirements and EMI filter size in inverter designs.
175°C maximum junction temperature	Supports high ambient operation in enclosed industrial enclosures and extends lifetime under thermal cycling stress.
Pb-free, RoHS-compliant plating	Meets global environmental compliance requirements without compromising solderability or long-term reliability.
JEDEC-qualified for industrial use	Validated for sustained operation in uninterruptible power supplies, welding equipment, and motor drives per JESD47.

Applications

Uninterruptible Power Supplies (UPS)

Industrial Welding Converters

Use Scenario: Online double-conversion UPS with 10–20 kHz PWM inverter stage delivering clean 50/60 Hz sine wave output.

IC Role / Device Role / Timing Role: Main switching device in full-bridge inverter; handles bidirectional energy flow and regenerative braking during battery charging.

Use Value: Low E_off (0.91 mJ) and soft diode recovery reduce transformer core loss and enable smaller magnetics and passive filtering.

Use Scenario: Inverter-based arc welding power supply with variable frequency control (15–30 kHz) for precise droop and pulse characteristics.

IC Role / Device Role / Timing Role: Primary switching element in primary-side DC–AC conversion; operates under high-current, high-dV/dt conditions with frequent short-circuit events.

Use Value: 5 µs short-circuit withstand time and 175°C rating allow reliable operation during arc ignition and stick-slip transitions without derating.

High-Frequency Motor Drives

Renewable Energy Inverters

Use Scenario: Compact HVAC compressor drive operating at 12–18 kHz with space-constrained heatsinking and forced air cooling.

IC Role / Device Role / Timing Role: Half-bridge leg switch in 3-phase inverter; modulated via space vector PWM with dead-time compensation.

Use Value: R_th(j–c) = 0.45 K/W enables 50 A continuous current at T_C = 100°C, reducing heatsink volume by ~30% vs. legacy 125°C-rated devices.

Use Scenario: Grid-tied solar string inverter with 20–25 kHz transformerless topology requiring high reliability and low leakage current.

IC Role / Device Role / Timing Role: DC–AC bridge switch; operates with unipolar modulation and active neutral-point clamping schemes.

Use Value: Low V_CE(sat) (1.85 V) minimizes conduction loss at partial load, improving weighted efficiency (EU efficiency) by up to 0.4%.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW50N60H3	Same die, identical electrical specs, but TO-247-3 non-isolated package (no insulated mounting flange).	Requires electrically isolated mounting hardware in grounded heatsink systems; unsuitable where creepage/clearance mandates insulation.	Select IKW50N60H3 only when mechanical isolation is provided externally and cost sensitivity outweighs assembly complexity.
FGA50N60UFD	Higher V_CE(sat) (2.2 V), slower t_d(off) (320 ns), no specified short-circuit rating, lower Q_G (240 nC).	Targeted at cost-sensitive consumer-grade SMPS; lacks JEDEC qualification and 175°C rating for industrial duty cycles.	Use FGA50N60UFD only in non-critical, low-duty-cycle applications where thermal margin exceeds 40°C and fault protection is external.

Compared with IKW50N60H3 and FGA50N60UFD, IGW50N60H3FKSA1 uniquely combines insulated TO-247 packaging, JEDEC industrial qualification, 5 µs short-circuit ruggedness, and lowest total switching energy-making it optimal for mission-critical industrial inverters requiring long-term reliability and minimal derating.

FAQ

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

The datasheet specifies r_G = 7 Ω as the test condition for switching characterization. Using r_G > 10 Ω increases td(off) and E_off, risking thermal runaway at high frequency; r_G < 5 Ω may cause gate oscillation and overshoot. For 20 kHz operation with 50 A load, 6.8–8.2 Ω is optimal to balance speed and stability.

Does IGW50N60H3FKSA1 include an integrated anti-parallel diode?

Yes-the device integrates a monolithically fabricated, soft-recovery anti-parallel diode on the same die. This diode exhibits low reverse recovery charge (Q_rr) and negligible tail current, confirmed in Figure E of the datasheet and validated in inductive load switching tests.

Can IGW50N60H3FKSA1 replace older H2-series IGBTs in existing designs?

Yes-IGW50N60H3FKSA1 is pin-compatible and electrically backward-compatible with IGW50N60H2, offering lower V_CE(sat) (1.85 V vs. 2.0 V), reduced E_off (0.91 mJ vs. 1.1 mJ), and extended T_vjmax (175°C vs. 150°C), enabling direct drop-in upgrade with measurable efficiency and thermal improvement.

Is the PG-TO247-3 package electrically insulated?

Yes-the "FKSA1" suffix denotes Infineon's insulated PG-TO247-3 variant: the metal flange is fully isolated from the collector terminal by a ceramic layer, providing 2500 V_AC isolation and eliminating need for insulating pads or shoulder washers in grounded heatsink assemblies.
