Infineon IPB60R070CFD7ATMA1: Redefining High-Voltage Power Conversion with CoolMOS™ CFD7 Technology

The Infineon IPB60R070CFD7ATMA1 stands at the forefront of high-voltage power transistor innovation, integrating the groundbreaking 700V CoolMOS™ CFD7 technology. This device is engineered to meet the escalating demands for efficiency, power density, and reliability in modern switch-mode power supplies (SMPS), industrial drives, and renewable energy systems.

A defining feature of this Power Transistor is its exceptionally low on-state resistance (RDS(on)) of just 70 mΩ, achieved through advanced superjunction technology. This ultra-low resistance minimizes conduction losses, enabling higher efficiency levels even under high-load conditions. Combined with reduced gate charge (Qg) and output capacitance (Coss), the device significantly cuts switching losses, allowing for higher switching frequencies. This capability is crucial for designers aiming to shrink the size of magnetic components and heat sinks, thereby boosting overall power density.

The CFD7 series incorporates a fast body diode that enhances hard-switching performance, making it particularly suitable for topologies like PFC (Power Factor Correction) and LLC resonant converters. This feature reduces reverse recovery losses and mitigates electromagnetic interference (EMI), contributing to both system efficiency and reliability. Furthermore, the 700V voltage rating provides a robust safety margin in applications prone to voltage spikes, such as those in industrial and automotive environments.

Packaged in the industry-standard TO-263-3 (D2PAK), the IPB60R070CFD7ATMA1 offers excellent thermal performance and mechanical durability. Its design supports automated assembly processes, making it ideal for high-volume manufacturing. Infineon’s commitment to quality ensures that this transistor delivers consistent performance and longevity, even in demanding operational conditions.
