Infineon SPW35N60C3: A High-Performance 600V CoolMOS™ Power Transistor for Efficient Switching Applications
The relentless pursuit of higher efficiency and power density in modern electronics has propelled the development of advanced power semiconductor technologies. At the forefront of this innovation is Infineon Technologies with its CoolMOS™ family. The SPW35N60C3 stands as a prime example, a 600V N-channel power MOSFET engineered to set new benchmarks in high-efficiency switching applications.
This transistor is built upon Infineon's proprietary Superjunction (SJ) technology, which is the cornerstone of its performance. This technology enables a drastic reduction in on-state resistance (RDS(on)) for a given silicon area. The SPW35N60C3 boasts an exceptionally low RDS(on) of 35 mΩ at room temperature, which directly translates to minimized conduction losses. When the device is in its on-state, less power is wasted as heat, leading to cooler operation and higher overall system efficiency.
Beyond conduction losses, switching performance is critical. The SPW35N60C3 features outstanding switching dynamics characterized by low gate charge (QG) and small reverse recovery charge (Qrr). These attributes ensure rapid turn-on and turn-off transitions, significantly reducing switching losses, which are predominant at high operating frequencies. This allows designers to push the switching frequency higher in applications like switch-mode power supplies (SMPS), leading to the use of smaller passive components such as transformers and capacitors, thereby increasing power density.
The robust 600V voltage rating provides a reliable safety margin for operation in universal mains applications (85 VAC – 305 VAC) and ensures enhanced resilience against voltage spikes and transients. Furthermore, the device offers a high level of dv/dt ruggedness and is qualified according to the latest JEDEC standards, guaranteeing high reliability and longevity in demanding environments.
Primary applications for the SPW35N60C3 include:
High-efficiency switched-mode power supplies (SMPS) for servers, telecom, and industrial equipment.
Power factor correction (PFC) stages, both passive and active.
Solar inverters and other renewable energy conversion systems.
Motor control drives and inverters.
