Infineon IPW60R037P7: A 600V CoolMOS™ P7 Power Transistor for High-Efficiency Switching Applications

The relentless pursuit of higher power density and energy efficiency in modern electronics places immense demands on power conversion systems. At the heart of these systems, the power switching transistor is a critical component whose performance directly dictates overall efficacy. The Infineon IPW60R037P7, a 600V CoolMOS™ P7 MOSFET, stands out as a premier solution engineered to meet these challenges in a wide array of high-performance applications.

This superjunction MOSFET is characterized by its exceptionally low on-state resistance (R DS(on)) of just 37 mΩ maximum. This ultra-low resistance is a cornerstone of its design, leading to significantly reduced conduction losses. When the transistor is switched on, less energy is wasted as heat, which directly translates to higher efficiency, especially in high-current scenarios. This makes the device particularly suitable for demanding power stages in server and telecom power supplies, industrial motor drives, and solar inverters.

Beyond minimal conduction losses, the CoolMOS™ P7 technology is optimized for switching performance. The device features superior switching dynamics and very low gate charge (Q G). The low gate charge means that the drive circuit can switch the transistor on and off very quickly and with less energy, minimizing switching losses. This is crucial for high-frequency operation, allowing designers to increase the switching frequency of their power supplies. A higher switching frequency, in turn, enables the use of smaller passive components like inductors and transformers, thereby increasing the overall power density of the system and allowing for more compact and lighter designs.

The 600V voltage rating provides a robust safety margin for operations in standard off-line power applications that typically operate from universal input voltages (85 VAC to 265 VAC). This headroom is essential for ensuring reliability and robustness against voltage spikes and transients commonly encountered in real-world environments. Furthermore, the P7 series is renowned for its high body diode dv/dt capability, enhancing its ruggedness and reliability in hard-switching topologies like power factor correction (PFC) circuits.

The TO-247 package offers an excellent thermal performance, facilitating efficient heat dissipation away from the silicon die. This allows the IPW60R037P7 to handle high power levels while maintaining a manageable junction temperature, further supporting the device's capability in high-power, continuous-operation applications.

ICGOOODFIND: The Infineon IPW60R037P7 CoolMOS™ P7 represents a significant leap in power MOSFET technology, offering a compelling blend of ultra-low conduction loss, fast switching capability, and high ruggedness. It is an ideal choice for designers aiming to push the boundaries of efficiency and power density in modern switch-mode power supplies and other demanding power conversion systems.
