Infineon Technologies IKU06N60R

Overview

IKU06N60R from Infineon is a 600V, 6A reverse-conducting (RC) IGBT with integrated freewheeling diode in PG-TO251-3 package, optimized for hard-switching motor drives and industrial inverters. It delivers 1.65V V_CE(sat) at 6A/25°C, 175°C max junction temperature, 5µs short-circuit withstand time, and operates up to 20kHz.

For engineers reviewing the IKU06N60R datasheet, IKU06N60R pinout, IKU06N60R application, or IKU06N60R equivalent, key selection criteria include conduction loss (V_CE(sat)/V_F), switching energy (E_ON/E_OFF), thermal resistance (R_thJC = 1.5K/W IGBT, 3.6K/W diode), and RC topology suitability for space-constrained half-bridge designs.

Technical Context

This RC-IGBT integrates a co-packaged fast-recovery diode with matched thermal characteristics, enabling single-package bidirectional current handling without external diode layout. Its TRENCHSTOP™ RC architecture balances low V_CE(sat) (1.65V) and low V_F (1.70V) while maintaining tight parameter distribution across production lots.

Designed for hard-switching operation up to 20kHz, it features smooth voltage/current transitions that reduce EMI generation, supported by 127ns turn-off delay and 152ns fall time at 25°C, with robust short-circuit capability (5µs at 15V V_GE, 400V V_CE).

Key Specifications

Pinout & Package

IKU06N60R uses the PG-TO251-3 surface-mount package (also known as IPAK), featuring isolated tab for simplified thermal mounting and creepage/clearance compliance. The package has three terminals: Collector (C), Gate (G), and Emitter (E), with the emitter connected to the exposed metal tab for low-inductance return path.

FAQ

What is the maximum recommended gate resistor value for IKU06N60R in 15kHz hard-switching?

The datasheet specifies a 23Ω external gate resistor for characterization testing at 15V drive. For 15kHz operation, a 15–27Ω resistor balances switching loss (E_ON/E_OFF = 0.33mJ total) and EMI control. Lower values increase dv/dt stress; higher values raise switching losses beyond 0.56mJ at 175°C junction temperature.

Can IKU06N60R replace a standard IGBT + external diode in an existing TO251 footprint?

Yes - IKU06N60R uses the exact PG-TO251-3 footprint and pinout (C-G-E) as standard TO251 IGBTs. The integrated diode replaces the external diode, requiring only layout revision to remove the discrete diode and reroute its cathode connection to the IGBT emitter.

Is the integrated diode in IKU06N60R optimized for soft recovery?

No - the diode exhibits t_rr = 68ns and Q_rr = 0.37µC at 25°C, characteristic of fast-recovery rather than soft-recovery diodes. Its di/dt capability (-211A/µs) supports hard-switching but may require snubbers in high-di/dt circuits.

What is the thermal resistance from junction to ambient for IKU06N60R on a standard 2-layer PCB?

With standard 2-layer FR4 and minimal copper (no thermal pad), R_thJA is approximately 75K/W per datasheet. Adding a 6cm² copper pour reduces it to ~50K/W - critical for sustaining 6A continuous current at T_C ≤ 100°C without forced air cooling.
