Infineon Technologies IKWH20N65WR6XKSA1

Overview

IKWH20N65WR6 from Infineon is a 650 V, 20 A TRENCHSTOP™ 5 IGBT with monolithic anti-parallel diode in PG-TO247-3-STD package, optimized for PFC and welding inverters. It features 1.7 V typical V_CE(sat) at 20 A/15 V, 0.2 mJ typical E_off at 25 °C, and enhanced creepage (>4.8 mm) and clearance (>3.4 mm) for industrial isolation compliance.

For engineers reviewing the IKWH20N65WR6 datasheet, IKWH20N65WR6 pinout, IKWH20N65WR6 application, or IKWH20N65WR6 equivalent, this device supports high-reliability switching in high-voltage AC-DC conversion, arc-stable welding power stages, and zero-current-switching (ZCS) topologies where low conduction loss and stable thermal behavior are critical.

Technical Context

This IGBT employs TRENCHSTOP™ 5 WR6 silicon technology with a positive temperature coefficient of V_CE(sat), enabling stable parallel operation without current-sharing resistors. Its monolithic diode exhibits soft reverse recovery (t_rr = 89 ns, Q_rr = 1 µC at 25 °C) and low forward voltage (V_F = 1.6 V typ. at 8.5 A).

The device is rated for 175 °C maximum junction temperature and delivers 1.1 K/W IGBT R_th(j–c) and 4.7 K/W diode R_th(j–c). Its gate charge (Q_G = 89 nC) and low C_res (9 pF) support efficient 20–100 kHz switching in hard- and soft-switched converters.

FAQ

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

The datasheet specifies RG(on)/RG(off) = 24 Ω for characterization. For 20 kHz operation with 15 V gate drive, a 15–27 Ω non-inductive resistor ensures td(on) ≤ 25 ns and td(off) ≤ 290 ns across –40 to 175 °C. Higher values increase switching losses and risk shoot-through in half-bridge configurations due to slower turn-off.

Can IKWH20N65WR6 be used in parallel without current-sharing components?

Yes. Its positive temperature coefficient of V_CE(sat) ensures inherent current balancing: as one device heats up, its V_CE(sat) rises, reducing its share of total current. Parallel operation has been validated with matched gate drive and symmetrical PCB layout-no external ballast resistors required.

Does the monolithic diode support bidirectional conduction in synchronous rectification?

No. The integrated diode is unidirectional and optimized for anti-parallel freewheeling-not synchronous rectification. Its soft recovery and low Q_rr make it ideal for PFC boost diodes and welder inverter freewheel paths, but it lacks the fast turn-on characteristics needed for controlled rectification.

What thermal interface material is recommended for mounting?

Infineon recommends thermally conductive silicone grease (e.g., Dow Corning TC-5123) or phase-change pads (e.g., Henkel Gap Pad VT-100) with 0.6 Nm M3 screw torque. Avoid thermal tapes-they increase R_th(j–c) by >0.3 K/W and compromise long-term bond integrity under thermal cycling.
