Infineon IDP20C65D2: A High-Efficiency 650V CoolMOS™ Power Transistor in D2PAK-7L Package

In the relentless pursuit of higher power density and energy efficiency in modern electronics, the choice of power switching device is paramount. The Infineon IDP20C65D2 stands out as a critical component engineered to meet these demanding challenges. This 650V superjunction MOSFET, built on Infineon's advanced CoolMOS™ P7 technology, represents a significant leap forward in performance for a wide array of power conversion applications.

Housed in the robust D2PAK-7L (TO-263-7) surface-mount package, this transistor is designed for high-current handling and superior thermal management. The package features an exposed copper leadframe, which dramatically reduces thermal resistance (RthJA). This design enables more efficient heat dissipation directly from the die to the PCB, allowing for higher power throughput and increased reliability in space-constrained designs.

The core of the IDP20C65D2's superiority lies in its exceptional electrical characteristics. It boasts an ultra-low on-state resistance (RDS(on)) of just 20mΩ, which is a key contributor to minimizing conduction losses. When combined with drastically reduced switching losses, the device ensures high efficiency across a broad operating range. This makes it an ideal solution for systems where energy conservation and thermal performance are critical, such as server and telecom power supplies, industrial motor drives, solar inverters, and EV charging infrastructure.

Furthermore, the CoolMOS™ P7 technology provides enhanced robustness and reliability. It offers improved avalanche ruggedness and incorporates an integrated source-drain diode with excellent reverse recovery characteristics, which is vital for hard-switching topologies like power factor correction (PFC) circuits.

ICGOOODFIND: The Infineon IDP20C65D2 is a premier 650V power MOSFET that masterfully balances ultra-low losses, high power density, and outstanding thermal performance. Its implementation of CoolMOS™ P7 in the D2PAK-7L package makes it a top-tier choice for designers pushing the boundaries of efficiency and reliability in next-generation power systems.
