They are also used in consumer electronics applications such as PC power supplies, adapters, TV power boards, fast chargers for mobile phones and electromagnetic heating products.
In order to meet the demand of high efficiency and minification of power supply system, Oriental Semiconductor has launched a new GreenMOS series of high voltage MOSFET, which adopts unique patented device structure and manufacturing process. GreenMOS product has faster switching speed and softer switching curve than conventional MOSFET, which can greatly restrain switch oscillation while obtaining extremely low dynamic loss. It can not only greatly improve system efficiency and reduce heating, but also simplify system EMI design.
Oriental Semiconductor’s SFGMOS Series MOSFET adopts Semi-Floating Gate structure, which combines the advantages of traditional planar structure and SGT structure of power MOSFET, and has the advantages of higher process stability and reliability, faster switching speed, smaller gate charge and higher application efficiency. SFGMOS Series MOSFET products cover the whole series of 20V~200V, which can be widely used in motor driver, synchronous rectification, etc.
Oriental Semiconductor's IGBT chips adopt a unique Trident-Gate Bipolar Transistor (TGBT) device structure to achieve lower on-state voltage drop and reduced switching losses.Multiple series of first and second-generation TGBT products have been successively launched, covering voltage ranges from 600V to 1700V. These products are suitable for applications such as photovoltaic energy storage inversion, DC charging piles, automotive main drive, OBC, and UPS. Additionally, Oriental has developed an ultra-high-speed series TGBT with an operating frequency of 60-100 kHz, which meets the demands of further high-frequency power systems while delivering higher efficiency.

Advanced power modules, including IGBTs, MOSFETs, SiC, Si/SiC hybrid modules, diodes, SiC diodes, and intelligent power modules. IGBT modules are used in applications such as main drive and DC-AC class solar inverters, energy storage systems, uninterruptible power supplies, and motor drives. MOSFET modules are used in automotive motor drives and on-board charger applications, with voltage ratings of 40 V, 60 V, 80 V, and 650 V, and use super-junction technology and inductive resistors.
Third-generation semiconductor material power devices are one of the important components of high-performance power devices in the future. The R&D team of Oriental has rich experience in wide bandgap semiconductor research and has developed a series of SiC MOSFETs.
Gallium Nitride High Electron Mobility Transistors (GaN HEMT) are increasingly becoming the choice for mainstream markets. For various high-voltage and low-voltage application scenarios, GaN HEMTs offer the fastest switching capabilities (with the highest dv/dt and di/dt) and superior energy efficiency performance. In addition, the self-developed GaN HEMTs by Oriental Semiconductor Co., Ltd. have reduced conduction losses and switching losses through innovative designs, further improving power density.
When connected in series with a power source, the OSP5050 high side OR-ing FET controller is used in conjunction with an external NMOSFET as an ideal diode rectifier. This OR-ing controller allows MOSFETs to replace diode rectifiers in distribution networks, thereby reducing power loss and voltage drop.
ApplicationThe products of Oriental Semiconductor cover a wide and specific range of application fields. In automotive electronics, the company has made in-depth deployment in electrification, covering on-board charging, various electronic control systems and thermal management. In the industrial and energy sectors, it provides solutions for battery testing, photovoltaic inversion and industrial power supplies. Meanwhile, its products also serve multiple key industries including consumer electronics (e.g., fast charging, televisions), household appliances (e.g., refrigerators, vacuum cleaners), communication facilities (e.g., data center power supplies) and motor drives (e.g., robots, UAVs, forklifts).
