Infineon IPS70R1K4P7S: A High-Performance 700V CoolMOS™ P7 Power Transistor

In the realm of high-efficiency power electronics, the demand for robust and highly efficient switching components continues to grow. Addressing this need, Infineon Technologies introduces the IPS70R1K4P7S, a 700V CoolMOS™ P7 power transistor that sets a new benchmark in performance and reliability for a wide range of applications, including switch-mode power supplies (SMPS), lighting, industrial drives, and renewable energy systems.

Built on Infineon’s advanced superjunction (SJ) technology, the IPS70R1K4P7S is engineered to deliver minimal switching and conduction losses, making it an ideal choice for high-frequency operations. With an ultra-low on-state resistance (\(R_{DS(on)}\)) of just 14 mΩ, this device significantly reduces power dissipation, leading to improved thermal performance and higher overall system efficiency. The 700V breakdown voltage ensures sufficient headroom for reliable operation even under high-voltage spikes and stressful conditions, enhancing system durability.

One of the standout features of the CoolMOS™ P7 series is its exceptional switching behavior, which allows for higher power density and smaller form factors in end applications. The transistor also incorporates integrated fast body diode characteristics, which help minimize reverse recovery losses and reduce electromagnetic interference (EMI). This makes the IPS70R1K4P7S particularly suitable for power factor correction (PFC) stages and hard-switching topologies like flyback and half-bridge converters.

Moreover, the device is designed with robustness in mind. It offers high avalanche ruggedness and strong immunity against gate voltage fluctuations, contributing to increased operational safety and longer service life. The TO-220 FullPAK package provides enhanced creepage distance, making it well-suited for applications requiring higher isolation standards.

In summary, the Infineon IPS70R1K4P7S exemplifies the evolution of power MOSFETs by combining high voltage capability, low losses, and superior switching performance. It empowers designers to create more efficient, compact, and reliable power systems.
