Analysis of Infineon IPP60R299CP 600V CoolMOS Power Transistor
The continuous evolution of power electronics demands semiconductor devices that offer higher efficiency, greater power density, and improved reliability. Infineon's IPP60R299CP, a 600V CoolMOS™ power transistor built on superjunction (SJ) technology, stands as a prominent solution addressing these needs in high-performance applications such as switched-mode power supplies (SMPS), power factor correction (PFC) stages, and lighting converters.
A core highlight of this device is its exceptionally low specific on-state resistance (RDS(on)) of 299 mΩ at room temperature. This is achieved through Infineon's advanced CoolMOS CP technology, which optimizes the charge balance in the silicon. The result is a significant reduction in conduction losses, allowing for higher efficiency operation and enabling the design of more compact power systems due to reduced heat generation.
Beyond static performance, the switching characteristics are equally impressive. The IPP60R299CP features low gate charge (QG) and low effective output capacitance (COSS(eff)). These parameters are critical for high-frequency switching operation. The minimized gate charge reduces driving losses and simplifies gate drive circuit design, while the reduced output capacitance directly cuts switching losses, particularly during the turn-on process. This combination allows systems to operate at higher switching frequencies, which in turn reduces the size and cost of passive components like magnetics and capacitors.

The robust 600V drain-source voltage rating provides a sufficient safety margin for universal mains applications (85 VAC – 305 VAC), ensuring reliable operation against line surges and transients. Furthermore, the technology boasts an intrinsic fast body diode. While hard switching of this intrinsic diode should generally be minimized, its improved reverse recovery characteristics contribute to lower losses and reduced electromagnetic interference (EMI) in certain topologies.
From a practical design perspective, the TO-220 FullPak (FPL) package offers a compelling advantage: it provides full isolation between the heatsink and the tab (drain potential). This eliminates the need for an insulating washer and mounting clip, simplifying the assembly process, reducing the thermal interface resistance, and ultimately improving thermal performance and system reliability.
In conclusion, the IPP60R299CP exemplifies the progress in high-voltage power MOSFET technology, striking an excellent balance between low conduction losses, superior switching performance, and application robustness.
ICGOOODFIND: The Infineon IPP60R299CP is a highly efficient 600V CoolMOS transistor that excels in minimizing both conduction and switching losses, making it an ideal choice for high-frequency, high-density power conversion designs where thermal performance and efficiency are paramount.
