Amidst the explosive growth in AI computing power, server power supplies are rapidly evolving towards higher efficiency and higher power density. As the core switching devices in power conversion systems, the performance of high-voltage power MOSFETs directly determines the overall energy efficiency and reliability of the system. Oriental Semiconductor’s OSG65R series of enhancement-mode N-channel power MOSFETs, utilising GreenMOS® super-junction technology, demonstrate significant advantages in key power stages of server power supplies, such as PFC boost converters and LLC resonant converters. Shenzhen Mingjiada Electronics Co., Ltd., a specialist distributor with nearly thirty years’ experience in the electronic components supply chain, maintains a long-term stock of genuine OSG65R series chips and is actively seeking to purchase and recycle inventory of these power devices at competitive prices.
I. OSG65R Product Overview: The Benchmark for Domestic High-Voltage Super-Junction MOSFETs
The OSG65R is an enhancement-mode N-channel high-voltage super-junction power MOSFET from Dongwei Semiconductor’s GreenMOS® series. Housed in a TO-247-3L package, it has been awarded the ‘China Chip’ prize for outstanding market performance. Based on an advanced charge-balanced process and utilising deep-trench etching and epitaxial fill technology, the device reduces on-resistance whilst optimising gate charge and switching losses. It incorporates an ultra-fast recovery body diode (FRD), making it suitable for resonant switching topologies; this effectively shortens reverse recovery time, thereby enhancing the conversion efficiency and operational stability of power supply systems.
As a benchmark product for domestically produced high-performance, high-voltage, high-current power devices, the OSG65R038HZF has succeeded in replacing comparable products from foreign brands, breaking the long-standing reliance on imports in the field of high-voltage super-junction MOSFETs.
