Infineon IKW40N65H5: A 650V 40A High-Speed TRENCHSTOP™ 5 IGBT for High-Efficiency Switching Applications
The relentless pursuit of higher efficiency and power density in modern power electronics drives the need for advanced semiconductor switches. Addressing this challenge, Infineon Technologies has introduced the IKW40N65H5, a 650 V, 40 A IGBT that stands as a benchmark for performance in high-speed switching applications. As a key member of the TRENCHSTOP™ 5 family, this device is engineered to deliver an optimal balance of low saturation voltage and minimal switching losses, making it an ideal solution for power supplies, industrial motor drives, and renewable energy systems.
At the core of the IKW40N65H5's superior performance is Infineon's advanced micro-pattern trench cell technology. This design significantly enhances channel density, which directly translates into a remarkably low collector-emitter saturation voltage (VCE(sat)). This low on-state voltage is crucial for minimizing conduction losses, especially at high operating currents, leading to cooler operation and improved system reliability. Furthermore, the device features a soft and fast reverse recovery body diode. This characteristic is paramount in hard-switching topologies like PFC (Power Factor Correction) circuits and inverters, as it drastically reduces reverse recovery currents and associated switching losses, while also mitigating electromagnetic interference (EMI).
The high-speed switching capability of the IKW40N65H5 allows designers to push the boundaries of switching frequency. Operating at higher frequencies enables the use of smaller and lighter passive components, such as inductors and transformers, which is a critical step towards achieving higher power density and reducing the overall system size and cost. The robust 650 V breakdown voltage provides a sufficient safety margin for operation in 400 V bus systems, ensuring resilience against voltage spikes and transients common in industrial environments.
Packaged in the industry-standard TO-247 package, the IKW40N65H5 offers excellent thermal performance and mechanical durability. Its design prioritizes ease of implementation into existing layouts, facilitating a straightforward upgrade path for legacy systems seeking a leap in efficiency.
