Product details

Overview

IKWH50N65WR6 from Infineon is a 650 V, 50 A TRENCHSTOP™ 5 IGBT with integrated fast-recovery diode in PG-TO247-3-STD package, designed for high-reliability industrial PFC and welding inverters. It features 1.85 V typical V_CE(sat) at 50 A/15 V, 0.73 mJ E_off at 25 °C, and enhanced creepage (>4.8 mm) and clearance (>3.4 mm) for contamination-prone environments.

For engineers reviewing the IKWH50N65WR6 datasheet, IKWH50N65WR6 pinout, IKWH50N65WR6 application, or IKWH50N65WR6 equivalent, key selection criteria include V_CE(sat) temperature stability, low E_sw at 175 °C, monolithic diode softness (trr = 87 ns), and TO-247 creepage compliance for industrial safety standards.

Technical Context

This IGBT employs TRENCHSTOP™ 5 WR6 silicon with optimized field-stop structure and positive V_CE(sat) temperature coefficient-enabling stable parallel operation without current-sharing resistors. Its monolithic diode exhibits low Q_rr (1.7 µC) and soft recovery (I_rrm = 28.4 A), critical for reducing voltage overshoot in ZCS PFC stages.

The device targets hard-switched and resonant topologies operating up to 175 °C junction temperature, with R_th(j-c) = 0.8 K/W for the IGBT and 3.2 K/W for the diode-supporting thermal design in compact, convection-cooled welder power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	650 V - supports 400 V AC input PFC and 600 V DC bus welding inverters with margin.
I_C	50 A continuous - rated for 100 °C case temperature, enabling 5 kW–7 kW industrial output without forced air.
V_CE(sat)	1.85 V typ @ 50 A/15 V/25 °C - low conduction loss reduces heatsink size by ~25% vs. older 2.2 V devices.
E_off	0.73 mJ @ 400 V/50 A/25 °C - enables 20–40 kHz switching in PFC while limiting total losses below 120 W.
trr	87 ns @ 25 °C - soft reverse recovery minimizes diode-induced voltage spikes during IGBT turn-on.
R_th(j-c)	0.8 K/W (IGBT) - allows direct mounting to aluminum baseplate with ≤1.2 K/W total thermal resistance to ambient.
Creepage	>4.8 mm - meets IEC 60664-1 Pollution Degree 3 requirements for uncoated PCBs in dusty factory environments.

Pinout & Package

PG-TO247-3-STD package with 3-pin through-hole configuration: Collector (C), Gate (G), Emitter (E). Enhanced creepage/clearance layout isolates collector pin from gate/emitter pins per JEDEC TO-247 mechanical standard.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (left)	Collector (C)	Main high-side power terminal; electrically isolated by >4.8 mm creepage from gate/emitter for reinforced insulation.
Pin 2 (center)	Gate (G)	Control input requiring ±20 V rating; low C_ies (3510 pF) enables fast, low-loss gate driving with 22 Ω resistor.
Pin 3 (right)	Emitter (E)	Power return and reference node for gate drive; shared emitter path with integrated diode cathode.

Key Features

Feature	Design Value
Positive V_CE(sat) tempco	Enables stable current sharing in paralleled IGBTs without external ballast resistors or active current balancing.
Monolithic diode with soft recovery	Q_rr = 1.7 µC and trr = 87 ns reduce EMI and snubber stress in high-dV/dt PFC boost stages.
Enhanced creepage & clearance	Pin-to-pin distances exceed 4.8 mm (creepage) and 3.4 mm (clearance), supporting pollution degree 3 certification.
Low E_sw at high temperature	E_off increases only 47% from 25 °C to 175 °C (0.73 → 1.07 mJ), preserving efficiency in thermally constrained welders.

Applications

PFC Boost Converter

Industrial Arc Welder Inverter

Use Scenario: 3.3 kW–5 kW single-phase or three-phase active PFC front-end for UPS and motor drives.

IC Role / Device Role / Timing Role: Main switching device in boost topology; operates at 20–40 kHz with zero-current switching assistance.

Use Value: Low V_CE(sat) and soft diode reduce conduction + switching losses to <1.8% total PFC loss at full load.

Use Scenario: Primary inverter stage in 5–10 kVA stick/tig welders with variable duty cycle and high peak current demands.

IC Role / Device Role / Timing Role: Half-bridge switch handling 150 A pulsed output; driven with 15 V gate voltage and 22 Ω gate resistors.

Use Value: Stable V_CE(sat) across -40 °C to 175 °C ensures consistent arc initiation and droop control under thermal cycling.

ZCS Resonant Converter

Induction Heating Inverter

Use Scenario: Zero-current-switched resonant DC-DC stage for battery charging systems requiring low EMI and high reliability.

IC Role / Device Role / Timing Role: High-side switch synchronized to resonant tank zero-current crossing; gate driven with precise dead-time control.

Use Value: Fast fall time (24 ns) and low E_off enable efficient 100 kHz operation with <0.5% switching loss increase over 25–125 °C range.

Use Scenario: 3–6 kW medium-frequency (20–50 kHz) induction heating inverter for metal hardening and brazing equipment.

IC Role / Device Role / Timing Role: Full-bridge IGBT switch managing 400 V DC bus and 100 A peak load currents with high di/dt capability.

Use Value: Integrated diode's low Q_rr and soft recovery suppress voltage spikes during commutation, eliminating need for external snubbers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES5	V_CE(sat) = 1.75 V @ 40 A; lower current rating; no enhanced creepage package.	Suitable for lower-power PFC (<3 kW); requires conformal coating for pollution degree 3 compliance.	Select when cost sensitivity outweighs creepage requirement and power level is ≤40 A RMS.
FGH40N60UFD	600 V rating; higher V_CE(sat) (1.9 V); TO-247-3 package with standard creepage (~3.2 mm).	Limited to 400 V AC input systems; not qualified for 650 V bus or harsh industrial environments.	Choose only for legacy 600 V designs where Infineon's WR6 reliability enhancements are not required.

Compared with IKW40N65ES5 and FGH40N60UFD, IKWH50N65WR6 delivers higher current capability, guaranteed creepage compliance, and superior thermal stability-making it the preferred choice for new 5–7 kW industrial PFC and welding platforms requiring long-term field reliability.

FAQ

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

The datasheet specifies RG(on)/RG(off) = 22 Ω for characterization. For 50 A operation at 40 kHz, a 15–22 Ω non-inductive gate resistor is recommended to balance switching speed (td(on) = 40 ns) and voltage overshoot. Lower values risk shoot-through; higher values increase E_on disproportionately due to slow Miller plateau transition.

Does the integrated diode support bidirectional current in bridge configurations?

Yes-the monolithic diode is an ultrafast, soft-recovery freewheeling diode rated for 24 A continuous and 50 A pulsed forward current. It conducts naturally during the IGBT's off-state in half-bridge or full-bridge topologies, with trr = 87 ns and low Q_rr ensuring minimal reverse recovery loss and voltage spike generation.

Can IKWH50N65WR6 be used in 800 V DC bus applications?

No-it is rated for 650 V V_CE maximum. Operating above 650 V violates absolute maximum ratings and risks catastrophic failure. For 800 V systems, consider Infineon's 1200 V TRENCHSTOP™ IGBTs (e.g., IKW20N120CS6) or SiC MOSFET alternatives with appropriate derating.

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

Yes-Infineon certifies IKWH50N65WR6 as fully RoHS 2011/65/EU and REACH SVHC-compliant. The lead-free finish uses matte tin plating on copper leads, and the epoxy mold compound meets UL 94 V-0 flammability rating with halogen-free formulation per IEC 61249-2-21.
