Product details

Overview

IKWH70N65WR6 from Infineon is a 650 V, 70 A TRENCHSTOP™ 5 IGBT with monolithic anti-parallel diode in PG-TO247-3-STD package. It delivers low V_CE(sat) (1.55–1.85 V at 25 °C), low E_off (1.07 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 IKWH70N65WR6 datasheet, IKWH70N65WR6 pinout, IKWH70N65WR6 application, or IKWH70N65WR6 equivalent, key selection criteria include its positive V_CE(sat) temperature coefficient enabling stable parallel operation, low diode reverse recovery charge (2.8 µC), and JEDEC-qualified reliability for high-voltage industrial power conversion.

Technical Context

This IGBT integrates a co-packaged fast soft-recovery diode optimized for boost PFC and inverter legs in welding equipment. Its TRENCHSTOP™ 5 WR6 process enables simultaneous reduction of conduction loss (V_CE(sat)) and switching loss (E_off), while maintaining robust short-circuit withstand time (≥5 µs at 15 V gate drive).

The device features a positive temperature coefficient for V_CE(sat), ensuring current sharing in paralleled configurations without external ballasting resistors. Thermal resistance R_th(j-c) is 0.5 K/W for the IGBT and 1.9 K/W for the diode - critical for thermal design in high-power, air-cooled industrial modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	650 V - supports 400 V AC input PFC stages with 1.5× safety margin against transients
I_C	70 A continuous - rated for 10 kW+ industrial welder output stages at T_c = 100 °C
V_CE(sat)	1.55–1.85 V @ 70 A/15 V - reduces conduction loss by ~25% vs. prior-generation 650 V IGBTs
E_off	1.07 mJ @ 400 V/70 A - enables >20 kHz switching in ZCS resonant converters with low thermal stress
Creepage distance	>4.8 mm - meets IPC-2221 Class B requirements for reinforced insulation in 600 V systems
Clearance distance	>3.4 mm - satisfies IEC 60664-1 pollution degree 2 spacing for industrial PCB layouts
T_vj(max)	175 °C - allows derated operation in sealed enclosures without forced airflow

Pinout & Package

PG-TO247-3-STD package with isolated mounting hole, standard lead pitch, and creepage-enhanced mold compound. Pin-to-pin creepage ≥4.8 mm and clearance ≥3.4 mm verified per IEC 60664-1.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC bus (+) in half-bridge; requires low-inductance layout due to 13 nH internal emitter inductance
Gate (G)	Control input for IGBT channel	Requires ±20 V max drive; gate charge Q_G = 218 nC dictates driver IC selection (e.g., 1ED020I12FA)
Emitter (E)	Common reference for IGBT and diode	Shared emitter node for integrated diode; must be low-impedance to minimize shoot-through risk in bridge topologies

Key Features

Feature	Design Value
Monolithic diode with soft recovery	Q_rr = 2.8 µC @ 25 °C - minimizes voltage overshoot and EMI in PFC boost diodes
Positive V_CE(sat) tempco	Enables stable current sharing in paralleled IGBTs without external emitter resistors
Low E_sw temperature dependence	E_on/E_off variation <15% from 25–175 °C - simplifies thermal compensation in digital gate drivers
JEDEC-qualified industrial reliability	Validated per JESD22-A108 (HTOL), JESD22-A110 (THB), and JESD22-A104 (TCT)

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65ES5	Lower I_C (40 A), higher V_CE(sat) (1.75 V typ), no enhanced creepage	Suitable for lower-power PFC (<8 kW); not qualified for welding duty cycles	Select when cost sensitivity outweighs thermal performance and creepage compliance
FGH70N60SMD	600 V rating, higher E_off (1.45 mJ), TO-247-4L package with Kelvin emitter	Better for high-frequency SMPS but lacks monolithic diode and creepage enhancement	Choose only if Kelvin emitter layout is mandatory and 650 V margin is unnecessary

Compared with IKW40N65ES5 and FGH70N60SMD, IKWH70N65WR6 uniquely combines 650 V/70 A rating, monolithic soft diode, and certified creepage/clearance - making it the sole option for JEDEC-qualified, space-constrained 10–25 kW industrial PFC and welding inverters requiring reinforced insulation.

FAQ

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

The datasheet specifies RG(on)/RG(off) = 15 Ω for characterization. For 70 A operation at 20 kHz, a 10–12 Ω gate resistor balances switching loss and EMI. Values above 18 Ω increase E_on/E_off by >22% and risk incomplete turn-on during high-dV/dt events. Use gate driver ICs with peak current ≥2 A to ensure robust edge control.

Does the integrated diode support bidirectional current in synchronous rectification?

No - the monolithic diode is unidirectional and optimized for anti-parallel freewheeling in inverter legs. Its soft recovery (trr = 98 ns) and low Qrr (2.8 µC) make it ideal for PFC and welding, but it lacks the reverse conduction capability required for true synchronous rectification. External MOSFETs or dedicated SR controllers are needed for bidirectional control.

How does the enhanced creepage affect PCB layout requirements?

The >4.8 mm creepage mandates minimum 5.0 mm trace-to-trace spacing between collector and emitter pads on the primary side, even under conformal coating. Standard FR-4 with 2 oz copper requires no slotting, but high-humidity environments demand hydrophobic solder mask. The package's molded-in creepage barrier eliminates need for isolation slots - reducing board area by ~12% vs. legacy TO-247.

Is this IGBT suitable for short-circuit conditions in motor drives?

Yes - it is characterized for short-circuit withstand time ≥5 µs at V_CE = 400 V, V_GE = 15 V, and T_vj = 150 °C. This supports hardware-based protection in industrial drives using fast desaturation detection (e.g., with DESAT pins on gate drivers like 1EDC60H12AH). Do not exceed 10 µs fault duration to avoid latch-up.
