Infineon IPP90R500C3: A High-Performance 900V CoolMOS™ Power Transistor
The relentless pursuit of higher efficiency and power density in modern electronics demands semiconductor components that deliver superior performance. The Infineon IPP90R500C3 stands out as a premier solution in this arena, a 900V superjunction MOSFET engineered to meet the rigorous demands of high-power applications. Built on Infineon's advanced CoolMOS™ C3 technology, this transistor sets a new benchmark for efficiency and reliability in switch-mode power supplies (SMPS), industrial drives, and renewable energy systems.
A key differentiator of the IPP90R500C3 is its exceptionally low effective on-state resistance (R DS(on)) of just 500mΩ at maximum gate voltage. This ultra-low resistance is the cornerstone of its high-efficiency operation, as it directly minimizes conduction losses. When the device is switched on, less energy is wasted as heat, leading to cooler operation and significantly higher overall system efficiency. This characteristic is paramount for designers aiming to meet stringent energy regulations and reduce the need for large, costly heat sinks.

Beyond static performance, the device excels in dynamic operation. The superjunction structure of the CoolMOS™ technology enables extremely low gate charge (Q G) and outstanding switching characteristics. This results in drastically reduced switching losses, especially during the critical turn-on and turn-off transitions. The low gate charge also means the device can be driven faster and with less effort from the controller IC, simplifying gate drive circuit design and further enhancing efficiency at high switching frequencies. This allows for the design of smaller magnetic components and capacitors, pushing the boundaries of power density.
Furthermore, the IPP90R500C3 is designed for robustness. Its high avalanche energy rating ensures resilience against voltage spikes and unpredictable transient events commonly encountered in harsh industrial environments. This intrinsic ruggedness, combined with its high voltage rating of 900V, provides a wide safety margin and enhances the long-term reliability of the end product.
ICGOOODFIND: The Infineon IPP90R500C3 is a top-tier 900V power MOSFET that masterfully balances ultra-low conduction losses, exceptional switching performance, and proven robustness. It is an optimal choice for engineers focused on maximizing efficiency and power density in demanding high-voltage applications.
