Infineon Technologies IKWH70N67PR7XKSA1

Overview

IKWH70N67PR7 from Infineon is a reverse-conducting TRENCHSTOP™ IGBT 7 PR7 optimized for boost PFC stages, featuring V_CE = 670 V, I_C = 70 A (DC), V_CE(sat) = 1.4 V (typ. at 25°C), improved EMI behavior via lower dv/dt, and monolithic integrated diode. It targets high-power, high-frequency industrial and HVAC PFC designs requiring stable thermal performance and parallel-switching capability.

For engineers reviewing the IKWH70N67PR7 datasheet, IKWH70N67PR7 pinout, IKWH70N67PR7 application, or IKWH70N67PR7 equivalent, key selection criteria include its 670 V blocking voltage, 70 A rated current, 0.48 K/W junction-to-case thermal resistance, positive temperature coefficient of V_CE(sat), and PG-TO247-3-U04 package with >4.8 mm creepage distance.

Technical Context

This RC-IGBT integrates a co-packaged, optimized fast-recovery diode in a single PG-TO247-3-U04 package, eliminating external anti-parallel diode requirements in boost PFC topologies. Its gate threshold voltage (V_GE(th) = 3.2–4.8 V) and transconductance (g_fs = 109 S) support robust drive margin and linear control across -40°C to 175°C junction temperatures.

The device delivers low switching losses (E_on = 1.58 mJ, E_off = 1.14 mJ at 400 V/70 A/25°C) and stable energy behavior over temperature, enabled by reduced output capacitance (C_oes = 49.4 pF) and reverse transfer capacitance (C_res = 19.6 pF). Its 2 kV HBM ESD rating and 0.62 K/W max R_th(j-c) ensure reliability in thermally demanding industrial environments.

FAQ

What is the maximum recommended gate resistor value for reliable switching at 100 kHz?

A 9.8 Ω gate resistor is validated in the datasheet for 400 V/70 A switching at 25°C and 175°C. At 100 kHz, use 6.8–10 Ω with active gate driving (±15 V) and local 100 nF decoupling; exceeding 12 Ω increases turn-on delay beyond 30 ns and risks shoot-through in half-bridge configurations.

Can IKWH70N67PR7 replace standard IGBTs without modifying the PCB layout?

Yes-it uses the industry-standard PG-TO247-3-U04 footprint with identical pinout (C-G-E) and mechanical dimensions as TO-247AC. However, its >4.8 mm creepage requires matching PCB slotting or conformal coating if replacing non-isolated variants in safety-critical designs.

Does the integrated diode support reverse recovery in hard-switched PFC?

Yes-the monolithic diode is optimized for soft reverse recovery with low Q_rr and controlled tail current, verified for 40–100 kHz boost PFC operation. It eliminates reverse recovery spikes seen with standard FRDs, reducing snubber stress and EMI.

What thermal interface material is recommended for mounting?

Infineon specifies 0.6 Nm mounting torque for M3 screws and recommends phase-change thermal pads (e.g., Laird TPCM 600 series) or silicone-based greases (e.g., Dow Corning TC-5622) with 0.05–0.10 mm bond line thickness to maintain R_th(j-c) ≤ 0.62 K/W under full-load conditions.
