Infineon IPA60R230P6 CoolMOS™ P6 Power Transistor: Datasheet, Application Notes, and Design Resources
The relentless pursuit of higher efficiency, power density, and reliability in power electronics has led to significant advancements in semiconductor technology. At the forefront of this innovation is Infineon's CoolMOS™ family, with the IPA60R230P6 standing out as a prime example of next-generation superjunction (SJ) MOSFET performance. This high-voltage Power Transistor is engineered to meet the demanding requirements of modern switched-mode power supplies (SMPS), industrial drives, and renewable energy systems.
Unpacking the Key Specifications
The heart of understanding any component lies in its datasheet. The IPA60R230P6 is characterized by a drain-source voltage (VDS) of 600 V, making it suitable for universal mains applications (85 V AC to 277 V AC). Its most headline-grabbing feature is its exceptionally low on-state resistance (RDS(on)) of just 230 mΩ (max. at 25°C), which is a key contributor to minimizing conduction losses. This low RDS(on) is achieved through Infineon's advanced CoolMOS™ P6 technology, which optimizes the charge balance in the silicon, leading to superior switching performance and reduced gate charge (QG).
The device is offered in a TO-220 FullPAK package, which provides full isolation between the heatsink and the tab (drain potential), simplifying mechanical assembly and improving safety.
Target Applications and Design Considerations
The technical attributes of the IPA60R230P6 make it an ideal choice for a wide array of applications:
Switch-Mode Power Supplies (SMPS): It is a perfect fit for high-efficiency telecom/server PSUs, ATX power supplies, and LED lighting drivers, particularly in PFC (Power Factor Correction) and LLC resonant converter stages.
Industrial Power Conversion: Used in motor drives, inverters for solar micro-inverters, and welding equipment where robustness and efficiency are critical.
Consumer Electronics: High-power adapters and chargers requiring compact form factors and high energy efficiency.
