Infineon Launches 80–100kW Power Modules for EVs
HybridPACK DC6i module with EDT2 technology
Thermal resistance from IGBT junction to coolant: 0.17K/W


As the adoption of electric vehicles accelerates globally, designing cost-effective traction inverters has become crucial. To achieve this, suitable power modules are required.

Infineon Technologies announced on the 11th that it is launching the 'HybridPACK DC6i', an IGBT power module for electric vehicle traction inverters with a power rating of 80kW to 100kW.

HybridPACK DC6i is a 6-pack module optimized for hybrid and small battery electric vehicles, offering a high price-to-performance ratio. In addition, heat management is easy, reducing raw material costs and making integration easy.

In Infineon's product portfolio, the HybridPACK DC6i is positioned between the HybridPACK1 family and the HybridPACK Drive family.

HybridPACK DC6i, which uses EDT2 IGBT technology, has the same footprint (7.2×14cm) as HybridPACK1, which uses IGBT3 technology, but provides more than 50% higher output power and uses 6 screws for connecting the DC link capacitor, which is 3 times more.

The stray inductance is low at 15 nH, and with the application of Infineon's direct cooling wave base plate, the thermal resistance from the IGBT chip junction to the coolant is 0.17 K/W. Therefore, it has excellent heat dissipation capabilities and can lower costs.

Designed with efficient automated mass production in mind, the DC6i can assemble gate driver boards in just seconds using press-fit pins and guide devices. Conventional selective soldering assembly takes more than one minute. The DC6i also meets the 'AQG 324' certification for automotive power modules.

Meanwhile, Infineon's EDT2 technology is a micro-pattern trench field stop cell design optimized for electric drivetrain applications. It features a 750V blocking voltage, an operating temperature of up to 175°C for a short period, and short-circuit robustness.

The design trade-off between switching loss and conduction loss is optimized for actual operating cycles with excellent light-load power loss, resulting in a 20 percent improvement in efficiency compared to Infineon's previous IGBT3 generation.

The HybridPACK DC6i has now started mass production and will be supplied through distributors starting this coming September.
