Infineon IPL65R130C7: A 650V CoolMOS™ C7 Power Transistor for High-Efficiency Applications
The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power conversion systems. At the heart of these systems, the power switch is a critical component whose performance directly impacts overall efficacy. The Infineon IPL65R130C7, a 650V CoolMOS™ C7 power transistor, stands out as a premier solution engineered to meet these challenges head-on, setting a new benchmark for performance in high-efficiency applications.
This device is part of Infineon's revolutionary CoolMOS™ C7 family, which is renowned for its superjunction (SJ) technology. The core innovation lies in its significantly reduced figure-of-merit (RDS(on) x Eoss), a key indicator of switching performance. A lower RDS(on) ensures minimal conduction losses when the transistor is on, while a reduced effective output capacitance (Eoss) translates to lower switching losses during the transition between on and off states. This optimal balance is crucial for achieving high efficiency, particularly in circuits operating at high switching frequencies.
The benefits of this technological leap are profound. By minimizing both switching and conduction losses, the IPL65R130C7 enables power supply designers to push the boundaries of switching frequency. Operating at higher frequencies allows for the use of smaller passive components, such as transformers, inductors, and capacitors. This directly contributes to a substantial increase in power density, allowing for more compact and lighter end-products without sacrificing performance or reliability. This is exceptionally valuable in applications like server and telecom power supplies, where space is at a premium.
Furthermore, the 650V voltage rating provides a robust safety margin for operation in universal mains applications (85 VAC – 305 VAC) and power factor correction (PFC) stages. This enhanced ruggedness ensures reliable operation under voltage spikes and harsh conditions. The device also features an integrated fast body diode, which improves hard commutation robustness, a critical factor in bridge topologies like totem-pole PFC.
Typical applications where the IPL65R130C7 excels include:
Server & Telecom Switched-Mode Power Supplies (SMPS)
Power Factor Correction (PFC) stages
Solar inverters and energy storage systems
Industrial motor drives and automation
High-performance LED lighting drivers
The Infineon IPL65R130C7 leverages advanced CoolMOS™ C7 technology to deliver an exceptional blend of low losses and high switching speed, making it an ideal cornerstone for designing next-generation, high-efficiency, and high-power-density conversion systems.
