Product details

Overview

IKWH40N65WR6 from Infineon is a 650 V, 40 A TRENCHSTOP™ 5 IGBT with integrated fast recovery diode in PG-TO247-3-STD package. It delivers low V_CE(sat) (1.55–1.85 V at 40 A/15 V), very low E_off (0.57–0.89 mJ), and enhanced creepage (>4.8 mm) and clearance (>3.4 mm) for industrial PFC and welding inverters operating up to 175 °C junction temperature.

For engineers reviewing the IKWH40N65WR6 datasheet, IKWH40N65WR6 pinout, IKWH40N65WR6 application, or IKWH40N65WR6 equivalent, this device supports high-reliability ZCS topologies, parallel switching via positive V_CE(sat) temperature coefficient, and stable thermal behavior across wide temperature ranges - critical for industrial power conversion design validation.

Technical Context

This IGBT-diode co-packaged device implements TRENCHSTOP™ 5 WR6 technology with monolithic integration of a soft-recovery, low-Q_rr diode optimized for PFC and welding applications. Its gate threshold voltage (3.2–4.8 V) and transconductance (89 S) support robust drive margin under high dv/dt noise conditions.

The device features low parasitic inductance (L_E = 13 nH), high short-circuit withstand time, and JEDEC-qualified reliability for industrial environments. Thermal resistance R_th(j-c) is 0.9 K/W for the IGBT and 4.2 K/W for the diode, enabling efficient heatsink coupling in high-power modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	650 V - Maximum blocking voltage compatible with 400 V AC input PFC stages and 600 V DC bus systems.
I_C	40 A continuous - Rated collector current at T_c = 100 °C, supporting compact heatsink designs in 3–5 kW converters.
V_CE(sat)	1.55–1.85 V @ 40 A/15 V - Low conduction loss enables >98% efficiency in hard-switched PFC and welder output stages.
E_off	0.57–0.89 mJ @ 400 V/40 A - Very low turn-off energy reduces switching losses and thermal stress during high-frequency operation.
Creepage/ Clearance	>4.8 mm / >3.4 mm - Enhanced isolation meets reinforced insulation requirements for industrial safety standards (IEC 61800, UL 61800).
T_vj(max)	175 °C - Extended junction temperature rating allows derated operation in high-ambient environments without forced cooling.
Q_G	117 nC - Gate charge value informs gate driver selection (e.g., 2–3 A peak drive capability required for <35 ns td(on)).

Pinout & Package

Package: PG-TO247-3-STD - Standard 3-pin through-hole package with isolated mounting hole, optimized for mechanical stability and thermal transfer in high-vibration industrial enclosures.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal of IGBT	Connected to DC bus or transformer primary; carries full load current and must be routed with low-inductance layout.
Gate (G)	Control input for IGBT switching	Requires low-impedance gate driver path; sensitive to noise due to 3.2–4.8 V V_GE(th) and 117 nC Q_G.
Emitter (E)	Common emitter node for IGBT and diode	Shared return path for both devices; internal emitter inductance (13 nH) impacts switching waveform fidelity.

Key Features

Feature	Design Value
Positive V_CE(sat) tempco	Enables stable current sharing in parallel IGBT configurations without external current-balancing resistors.
Monolithic diode with low Q_rr	1.4–2.5 µC reverse recovery charge minimizes diode-induced voltage spikes and EMI in PFC boost stages.
Enhanced creepage & clearance	Pin-to-pin distances exceed 4.8 mm creepage and 3.4 mm clearance - eliminates need for conformal coating in Class II insulation designs.
Low E_sw temperature dependence	Turn-on/off energy variation <25% from 25 °C to 175 °C - ensures predictable thermal management across full operating range.
JEDEC-qualified reliability	Validated per JEDEC47/20/22 for industrial use - supports 10+ year field life in unattended welding equipment and UPS systems.

Applications

Industrial PFC Rectifiers

IGBT-Based Welding Inverters

IC Role / Device Role / Timing Role: High-side IGBT switch in interleaved boost topology, operating at 20–50 kHz with zero-current switching assistance.

Use Value: Low V_CE(sat) and E_off reduce conduction + switching losses by 18% vs. legacy TRENCHSTOP 4, enabling smaller heatsinks and fanless operation.

Use Scenario: Output inverter stage in 3-phase MIG/MAG welding machines delivering 200–400 A arc current.

IC Role / Device Role / Timing Role: Main switching device in full-bridge inverter driving resonant LC tank; handles repetitive 120 A pulsed currents.

Use Value: Stable V_CE(sat) over temperature prevents current runaway during sustained arc duty cycles, improving weld consistency and electrode life.

ZCS Resonant Converters

Uninterruptible Power Supplies

Use Scenario: Zero-current switching half-bridge in telecom rectifier modules operating at 100 kHz with 48 V/200 A output.

IC Role / Device Role / Timing Role: Resonant switch with soft-commutation; leverages low trr diode for natural turn-off zero-current detection.

Use Value: Diode trr of 79–104 ns and low dirr/dt (383–821 A/µs) suppresses voltage overshoot during resonant transitions, reducing snubber losses by 30%.

Use Scenario: Online double-conversion UPS with 10 kVA capacity and battery backup for data center servers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT-diode co-packaged applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES6	Same 650 V/40 A rating but uses TRENCHSTOP™ 5 ES6 technology; higher V_CE(sat) (1.75 V typ) and no enhanced creepage package.	Lacks >4.8 mm creepage; unsuitable for reinforced insulation systems requiring extended air gaps.	Select when cost sensitivity outweighs safety certification needs and board-level creepage can be managed externally.
FGH40N60UF	600 V rating, lower V_CE(sat) (1.45 V), but only 150 °C T_vj(max) and no monolithic diode - requires external diode.	Not suitable for space-constrained PFC where integrated diode saves PCB area and reduces parasitics.	Prefer for 400 V AC input systems where 600 V blocking suffices and discrete diode placement is acceptable.

Compared with IKW40N65ES6 and FGH40N60UF, IKWH40N65WR6 uniquely combines reinforced insulation compliance, monolithic diode integration, and 175 °C operation - making it the only choice for certified industrial PFC and welding inverters demanding long-term reliability without external creepage enhancement.

FAQ

What is the maximum recommended gate resistor for reliable switching?

The datasheet specifies RG(on)/RG(off) = 27 Ω for characterization. For 40 A operation at 175 °C, a 15–22 Ω gate resistor is recommended to balance switching speed (td(on) ≈ 34 ns) and voltage overshoot control. Lower values increase dv/dt stress; higher values raise E_on/E_off and thermal load.

Can IKWH40N65WR6 be used in parallel without current-sharing resistors?

Yes - its positive temperature coefficient of V_CE(sat) ensures inherent current balancing. At 175 °C, V_CE(sat) rises to 1.8 V (vs. 1.55 V at 25 °C), causing hotter devices to conduct less. Parallel operation requires matched gate drive paths and symmetrical layout to avoid dynamic imbalance.

Does the integrated diode support soft recovery in PFC applications?

Yes - the monolithic diode exhibits soft reverse recovery with trr = 79 ns (25 °C) and low Irrm (24.7 A), minimizing voltage spikes and EMI. Its Q_rr increases only moderately to 2.5 µC at 175 °C, preserving PFC efficiency across full thermal range without snubber redesign.

Is the PG-TO247-3-STD package RoHS and REACH compliant?

Yes - Infineon confirms full RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 compliance for IKWH40N65WR6. The package uses lead-free matte tin plating and halogen-free molding compound, with full material declarations available via Infineon's Eco Reports portal.
