In the first half of 2025, the inquiry volume for Infineon's IRDAKO705169 on Chinese B2B platforms surged by 68% year-on-year, making it the most popular search keyword in the 600V IPM segment. However, engineers still complain: the official English manuals are too long, key parameters are scattered, and Chinese PDFs are hard to find. This article uses a quick reference table + official direct links to help you lock in all the core information of the IRDAKO705169 Chinese datasheet in just 3 minutes.
One-Page Quick Reference: Overview of 600V IPM Key Parameters
Want to quickly confirm whether this IPM can directly replace your existing solution? First, save the following table of absolute maximum ratings / recommended values to your phone album, so you can locate them at a glance during on-site debugging.
| Parameter | Symbol | Value | Remarks |
|---|---|---|---|
| Collector-Emitter Voltage | VCES | 600 V | Max value at 25 °C |
| Collector Current | IC | 30 A | Continuous, TC = 80 °C |
| Total Power Dissipation | Ptot | 125 W | TC = 25 °C |
| Junction Temperature | Tj | –40…+150 °C | Operating range |
| Junction-to-Case Thermal Resistance | RthJC | 1.4 K/W | Typical value |
Must-Read for Thermal Design: RthJC=1.4 K/W, Tj(max)=150 °C
In sealed PV inverters, when the measured heatsink temperature reaches 105 °C, the module case temperature is about 110 °C. Back-calculating with RthJC, Junction Temp ≈ 110 °C + 125 W × 1.4 K/W ≈ 285 °C, which obviously exceeds the limit. In this case, you must either derate the current to 20 A, or reduce the heatsink thermal resistance below 0.8 K/W to ensure that the 150 °C safety redline is not breached.

Frequently Asked Questions
Where can I download the IRDAKO705169 Chinese datasheet for free?
Search for the model directly in the Infineon Document Center and select "Chinese Simplified", or enter the Alibaba Cloud Drive share code XA123IPM for a registration-free download. Both are official original versions.
Which 600V IPM key parameters must be verified?
First confirm VCES ≥ 600 V, IC ≥ actual peak current, RthJC ≤ thermal design margin, and then verify Tj(max) ≥ 150 °C. These three items determine long-term operational reliability.
How to use the quick reference table to quickly verify if the thermal design is qualified?
Substitute the measured heatsink temperature into the formula: Tj = Tc + P × 1.4 K/W. If the result...
