Product details

Overview

IGW40N65H5FKSA1 from Infineon is a 650V, 40A high-speed TRENCHSTOP™ 5 IGBT in PG-TO247-3 package, optimized for hard-switching and resonant topologies in industrial power converters. It delivers 1.65V V_CE(sat) at 40A/25°C, 95nC gate charge, and 175°C maximum junction temperature, enabling efficient operation in solar inverters and UPS systems.

For engineers reviewing the IGW40N65H5FKSA1 datasheet, IGW40N65H5FKSA1 pinout, IGW40N65H5FKSA1 application, or IGW40N65H5FKSA1 equivalent, key selection criteria include switching energy (0.14–0.76 mJ), thermal resistance (R_th(j-c) = 0.60 K/W), collector-emitter breakdown voltage, gate threshold voltage (4.0V typ), and safe operating area at elevated temperatures.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop technology to achieve low conduction loss and fast switching with minimized tail current. Its dynamic parameters-19–22 ns turn-on delay, 4–12 ns rise time, and 165–240 ns turn-off delay-are specified across 5A–40A load currents and 25°C–150°C junction temperatures.

The device integrates a monolithic anti-parallel diode with soft recovery characteristics, supports ±20V DC and ±30V transient gate-emitter voltage, and operates within a -40°C to +175°C junction temperature range while maintaining stable V_CE(sat) up to 1.95V at 175°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	650V - Withstands DC bus voltages up to 650V in boost, inverter, and converter stages without avalanche stress.
I_C	40A continuous - Supports sustained 40A collector current at T_C = 25°C, derating to 46A at T_C = 100°C per thermal limits.
V_CE(sat)	1.65V @ 40A/25°C - Low saturation voltage reduces conduction losses and improves system efficiency in high-current switching nodes.
Q_G	95nC - Enables fast, low-loss gate drive with moderate gate resistor selection (e.g., 15Ω) for balanced E_on/E_off.
R_th(j-c)	0.60 K/W - Allows direct heatsink mounting with predictable thermal drop; enables >200W dissipation at ΔT = 120K.
T_vj(max)	175°C - Supports high ambient or high-power-density designs with extended reliability margin under transient overloads.
E_ts	0.14–0.76 mJ - Total switching energy varies with load and temperature; critical for calculating total losses in 10–100 kHz converters.

Pinout & Package

IGW40N65H5FKSA1 uses the PG-TO247-3 package: insulated plastic case with isolated metal tab (collector), three leads, and screw-mount capability. The package provides low thermal resistance and robust mechanical mounting for industrial power modules.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal accepting ±20V DC / ±30V transient drive; requires low-inductance gate loop to minimize oscillation during fast transitions.
Pin 2 & backside	Collector	Main high-side power terminal; electrically connected to metal tab for direct heatsink attachment and low-inductance current path.
Pin 3	Emitter	Power return node; internal emitter inductance is 13.0 nH (measured 5 mm from case), influencing switching waveform fidelity.

Key Features

Feature	Design Value
Best-in-class hard-switching efficiency	Combines low V_CE(sat) (1.65V) and low Q_G (95nC) to minimize combined conduction and switching losses in 10–50 kHz applications.
Plug-and-play replacement for prior generations	Pin-compatible and electrically compatible with earlier TRENCHSTOP™ IGBTs (e.g., H3/H4), simplifying upgrade paths without board redesign.
JEDEC-qualified reliability	Validated for industrial power control applications per JEDEC standards, supporting long-term operation under thermal cycling and humidity stress.
Pb-free and RoHS-compliant	Lead plating meets EU RoHS Directive 2011/65/EU; suitable for environmentally regulated industrial and renewable energy equipment.

Applications

Solar Converters

Uninterruptible Power Supplies

IC Role / Device Role / Timing Role: Main switching device in three-phase inverter bridge; handles bidirectional reactive power flow and grid-synchronization timing.

Use Value: Low E_off (0.05–0.22 mJ) and soft diode recovery reduce EMI and thermal stress during zero-crossing commutation.

Use Scenario: Online double-conversion UPS output inverter delivering clean 50/60 Hz sine wave under variable load conditions.

IC Role / Device Role / Timing Role: High-efficiency power switch in full-bridge or three-phase inverter; synchronized to battery-charger and bypass-control logic.

Use Value: 175°C T_vj(max) and stable V_CE(sat) enable reliable overload handling (e.g., 150% for 60 s) without derating.

Welding Converters

Mid-to-High Frequency SMPS

Use Scenario: Inverter-based arc welding power supply with 20–100 kHz PWM modulation for precise current control and arc stability.

IC Role / Device Role / Timing Role: Primary-side switching element in resonant LLC or phase-shifted full-bridge topology; controls duty cycle and frequency modulation.

Use Value: Fast turn-off (165–240 ns td(off)) and low tail current minimize energy loss during high-di/dt current transitions in short-circuit events.

Use Scenario: Industrial AC-DC front-end or isolated DC-DC converter operating at 50–100 kHz for factory automation and motor drives.

IC Role / Device Role / Timing Role: High-voltage switch in active clamp forward or half-bridge configuration; manages primary-side energy transfer timing and reset.

Use Value: R_th(j-c) = 0.60 K/W and 250W P_tot at T_C = 25°C support compact heatsink design in space-constrained enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IGP40N65H5	Same die, PG-TO220-3 package; higher R_th(j-a) (62 K/W vs. 40 K/W); lower P_tot at T_C = 100°C (125W vs. 250W).	Limited to lower-power (<1.5 kW), natural-convection-cooled designs; unsuitable for forced-air or high-ambient environments.	Select when cost sensitivity outweighs thermal performance and board space allows larger heatsink footprint.
IKW40N65ES5	650V/40A TRENCHSTOP™ 5 IGBT with integrated co-packaged diode; same PG-TO247-3; slightly higher V_CE(sat) (1.75V typ) but improved diode softness.	Better suited for ZVS/ZCS topologies requiring ultra-soft diode recovery; preferred in high-frequency resonant converters.	Select when diode reverse recovery behavior dominates system EMI or efficiency, not raw IGBT switching speed.

Compared with IGP40N65H5 and IKW40N65ES5, IGW40N65H5FKSA1 offers optimal balance of low gate charge, low saturation voltage, and superior thermal interface-making it ideal for forced-air-cooled, medium-to-high-power industrial inverters where layout inductance and heatsink mass are constrained.

FAQ

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

The datasheet specifies RG(on) = RG(off) = 15Ω for characterization. For reliable operation, use 10–22Ω to limit peak gate current while maintaining <25 ns rise/fall times. Higher values increase switching losses and risk shoot-through in bridge configurations due to delayed turn-off.

Does IGW40N65H5FKSA1 include an integrated freewheeling diode?

No-it is a discrete IGBT without an integrated diode. A separate ultra-fast, soft-recovery anti-parallel diode (e.g., IDH08SG60C) must be used in inverter legs. The device's internal emitter inductance (13.0 nH) affects diode commutation dynamics and should be accounted for in layout.

Can this IGBT operate safely at 100 kHz switching frequency?

Yes, but only at reduced current levels. At 100 kHz, conduction and switching losses scale significantly; operation above 50 kHz requires strict thermal management, low-inductance layout, and derated I_C (≤20A) to maintain T_vj ≤ 150°C under typical heatsink conditions.

What is the meaning of "FKSA1" in the part number?

"FKSA1" is Infineon's packaging and compliance suffix: F = TO247 package, K = lead-free/RoHS-compliant plating, S = tape-and-reel packaging, A1 = revision level and internal manufacturing code. It does not indicate functional differences from IGW40N65H5.
